  • Page 25: Copy Processes Around The Drum

    31 August 1989 3. COPY PROCESSES AROUND THE DRUM DRUM CHARGE In the dark, the charge corona unit gives a uniform positive charge to the selenium drum. The charge remains on the surface of the drum because the photoconductive selenium has electrical resistance in the dark.
  • Page 26 31 August 1989 ERASE The erase lamp illuminates the areas of the charged drum surface that will not be used for the copy image. The resistance of the drum in the illuminated areas drops and the charge on those areas dissipates. DEVELOPMENT Negatively charged toner is attracted to the positively charged areas of the drum, thus developing the latent image.

  • Page 28: Paper Path

    31 August 1989 5. PAPER PATH Paper feed starts from one of the four paper feed stations. The copy paper then follows one of two paths inside the copier. The path followed depends on which mode the operator has selected. For copy processing, all sheets follow the same path from the paper feed mechanism through the fusing unit.
  • Page 29 31 August 1989 Paper Separation: The electrostatic attraction between the paper and the drum is broken by the separating corona. The suction of the vacuum fan and the weight of the paper pulls the paper onto the transport belt. The transport belt moves the paper with the developed copy image to the fusing unit.
  • Page 30 31 August 1989 2. DUPLEX COPY PATH Inverter Unit: The junction gate directs the paper to the inverter unit, which inverts the copy and sends it to the duplex transport unit. Duplex Transport: The duplex transport rollers move the copy to the right. The appropriate fork gate is opened according to the paper size.

  • Page 51: Drum Heater Control

    31 August 1989 1.3 DRUM HEATER CONTROL The drum heater receives 100 volts ac only when the main switch is turned off. When the main switch is turned on, the 100 volt ac current stops flowing.
  • Page 52: Drum Charge

    31 August 1989 2. DRUM CHARGE This copier uses a dual wire corotron unit and a highly sensitive selenium drum. The corona wires [A] generate a flow of positive ions when the charge power pack applies a high positive voltage to the corona unit. The drum coating [B] receives a uniform positive charge as it rotates past the corona unit.
  • Page 53: Wire Cleaner

    31 August 1989 2.2 WIRE CLEANER Paper dust or toner particles on the corona wires [A] may interfere with charging. The wire cleaner [B] corrects this problem by automatically wiping the charge corona wires clean. Pads on the wire cleaner bracket clean the corona wires as the dc motor [C] drives the cleaner bracket from the home position to the rear end of the corona unit and then back again.
  • Page 54: Charge Corona Power Pack

    31 August 1989 2.3 CHARGE CORONA POWER PACK The circuit operation for the charge corona begins with the input of +5 volts (Vc) at CN2-3. This voltage powers the LED of the photocoupler. Additionally, 24 volts (Vp) enters the power pack at CN1-1. This power supply is used to produce the high voltage corona.
  • Page 55: Optics

    31 August 1989 3. OPTICS 3.1 OVERVIEW During the copy cycle, an image of the original is reflected onto the surface of the drum [I] via the optics assembly. The optics assembly consists of the following parts: 1. First Scanner [A]: Exposure lamp [B] (85V, 160W) First mirror AD (Auto Density) sensor [C]...
  • Page 56 31 August 1989 This copier has nine standard reproduction ratios: five reductions, three enlargements and full size. In addition, it has a zoom function. The reproduction ratio can be selected in one percent steps from 60% to 155%. A servomotor drives the first and second scanners during the copy cycle. This motor is controlled by the optics PCB, which changes the motor speed depending on the reproduction ratio.
  • Page 57: Exposure Lamp Control

    31 August 1989 3.2 EXPOSURE LAMP CONTROL After the Start key is pressed, the main PCB sends the exposure lamp trigger signal [C] to CN501-6 on the ac drive board. The width of the lamp trigger pulse is based on the setting of SP mode #48 and on the zero-cross signal [B] from the ac drive board.
  • Page 58: Scanner Drive

    31 August 1989 3.3 SCANNER DRIVE This model uses a dc servomotor [A] to drive the first [B] and second [C] scanners. This first scanner is attached to the scanner drive wire by the wire clamp [D]. The second scanner is connected to the scanner drive wire by a movable pulley [E] (the second scanner pulley).
  • Page 59: Scanner Motor Control

    31 August 1989 3.4 SCANNER MOTOR CONTROL The scanner drive motor is a dc servomotor. The CPU on the optics board controls the speed of this servomotor. The main CPU and the optics CPU communicate through a serial interface bus (TXD/RXD). After the main CPU sends the scanner start signal to the optics CPU, the optics CPU receives the drum speed data from the main PCB (pulse generator).
  • Page 60: Lens/Mirror Posltioning

    31 August 1989 3.5 LENS/MIRROR POSITIONING Lens Drive The lens drive motor (stepper motor) [A] changes the lens position according to the selected reproduction ratio to provide the proper horizontal magnification between the lens and the drum’s surface. The output gear of the lens drive motor engages the gears [B] of the lens drive pulley. The lens drive wire [C] is wrapped around the lens drive pulley and is connected to the lens drive bracket [D].
  • Page 61 31 August 1989 [A] - Lens Drive Pulley [B] - Lens Housing The lens home position sensor [C] informs the optics PCB when the lens [D] is at the full-size position (home position). The optics PCB determines the lens stop position in reduction and enlargement modes by counting the number of steps from the home position.
  • Page 62 31 August 1989 Home position is checked by moving the lens from the enlargement side towards the reduction side. So, when home position is checked, a LOW to HIGH to LOW signal is present at CN305-9 of the optics board. This occurs when the actuator blade enters and exits the lens home position sensor.
  • Page 63: Fourth And Flfth Mlrror Assembly

    31 August 1989 3.6 FOURTH AND FIFTH MIRROR ASSEMBLY When the reproduction ratio is changed, the stepper motor [A] moves the fourth and fifth mirror assembly [B] using the wire [C] and pulleys [D]. This provides the proper focal distance between the original and the drum. When the fourth and fifth mirror assembly is in the full-size position, the actuator [E] on the assembly actuates the fourth/fifth mirror home position sensor [F].
  • Page 64 31 August 1989 Fourth and Fifth Mirror Assembly Positioning The mirror home position sensor informs the optics CPU when the fourth and fifth mirror assembly is at the home position. The home position is determined by a LOW to HIGH to LOW change on CN305-12 of the optics board.

    31 August 1989 3.7 ORIGINAL SIZE DETECTION NOTE: With the F33\34, original size detection is performed using the OL and OW sensors in the ARDF unit. For more information, see the ARDF options section. 3.8 RELATED SERVICE CALL CONDITIONS Code #11: Exposure Lamp Malfunction Definition: Lights if the lamp filament breaks or if the lamp turns on during ready or please wait modes.
  • Page 66 31 August 1989 Code #22: Scanner Home Position Sensor Stays High Definition: Lights if the scanner home position sensor is open at power up. Observation: Scanner eventually moves to the extreme right as on/off key is activated until code 2d is displayed.
  • Page 67 31 August 1989 Code #28: Lens Home Position Sensor Stays Low Definition: Lights if the lens is moving toward enlargement and the H.P. sensor stays at a LOW signal level for longer than 3.82 seconds. Observations: The lens always moves toward enlargement at power-up. The lens is to the right of the H.P. sensor and the lens motor does not turn on.
  • Page 68 31 August 1989 Code #2A: 4th/5th Mirror Home Position Sensor Stays Low Definition: Lights when the 4th/5th mirror sensor home position sensor does not actuate within 1.83 seconds after the mirror motor turns on. Observations: At power-up, the 4th/5th mirror drive rotates counterclockwise past the home position sensor. If the main switch is turned off and on, the mirror motor emits a noise and stays at the home position.
  • Page 69 31 August 1989 Code #2D: No Encoder Output Definition: Lights durnig a copy cycle when the output frequency from the scanner motor encoder is not detected for 490 milliseconds after the scanner motor is energized or if the scanner home position sensor opens or shorts during a copy cycle.

  • Page 71: Lead Edge And Trailing Edge Erase

    31 August 1989 4.2 LEAD EDGE AND TRAILING EDGE ERASE The entire bank of erase lamps turns on to erase the drum before and after the image area. Leading edge erase overlaps the paper and the image slightly. The leading edge margin helps prevent fusing jams by making it easier for the stripper pawls to separate the paper from the hot roller.
  • Page 72: Edge Erase Function

    31 August 1989 4.4 EDGE ERASE FUNCTION The edge erase function erases a border around the copy. The border is adjustable in 4 steps using SP mode #38. These borders are approximately 5, 10, 15, and 20 millimeters wide, but vary slightly according to paper size and the selected reproduction ratio.
  • Page 73: Erase Lamp Circuit

    31 August 1989 4.5 ERASE LAMP CIRCUIT This copier uses 80 LEDs in the erase lamp unit. The large number of LEDs allows precise control of the side erase margins. Shift register drivers control the LEDs. Initially, the ENABLE signal (LOW active) sets all shift registers to OFF.
  • Page 74: Development

    31 August 1989 5. DEVELOPMENT 5.1 OVERVIEW When the main motor sends a signal to the SSR PCB, the development motor is energized. When it turns on, the paddle roller [A] and development roller [B] start turning. The paddle roller picks up developer in its paddles and transports it to the development roller. Internal permanent magnets in the development roller attract the developer to the development roller sleeve.
  • Page 75: Developer Exchange Unit

    31 August 1989 5.2 DEVELOPER EXCHANGE UNIT The developer exchange plate [A] enables the removal of developer from the development unit. The developer inlet cover [B] enables the addition of developer to the development unit without separating the toner tank from the development unit. SP87 sets the PM cycle. When a predetermined count is reached, the service call indicator blinks, the guidance display indicates “Call for maintenance”, and the start key stays green.
  • Page 76: Drive Mechanlsm

    31 August 1989 5.3 DRIVE MECHANISM A: Development Drive Gear B: Development Roller Gear C: Idle Gear D: Auger Gear The gears of the development unit and the toner agitator gear are driven by the development drive gear [A] when the development motor turns. The rotation is transmitted as follows: The development drive gear and development roller gear are helical gears.
  • Page 77 31 August 1989 5.4 CROSSMIXING The crossmixing mechanism has two functions: it keeps the toner and developer evenly mixed, and it helps to agitate the developer. The developer that is attracted to the development roller at point [A] is split into two parts by the doctor blade.
  • Page 78: Image Denslty Control

    31 August 1989 5.5 IMAGE DENSITY CONTROL Image density is controlled in two ways: 1) by changing the strength of the bias voltage applied to the development roller sleeve, and 2) by changing the strength of the voltage applied to the exposure lamp. Applying a bias voltage to the development sleeve reduces the potential between the development roller and the drum, which reduces the amount of toner transferred;...
  • Page 79 31 August 1989 Auto Image Density Control Leading edge of original When automatic image density control is selected, the exposure lamp voltage is set at position 4. Image density is controlled only by changing the bias voltage. At the start of the copy cycle the original sensing mechanism measures the background density of the original image.
  • Page 80 31 August 1989 Auto ID Peak Hold Input Voltage The CPU checks the voltage output by the auto ID circuit. This circuit has a peak hold function. The peak hold voltage corresponds to the maximum reflectivity of the original. Based on the peak hold voltage, the CPU determines the proper bias base level and sends a 4-bit control signal to the power pack.
  • Page 81 31 August 1989 Bias Compensation Factors As discussed previously, the bias base level is set either by the automatic image density system or by the operator through the image density keys. The CPU increases the base bias level as necessary to compensate for the rest time between copy runs and the drum temperature, both of which affect drum sensitivity.
  • Page 82 31 August 1989 2) Drum Temperature Compensation The CC/Bias power pack monitors drum temperature through a thermistor (TH-1), and it increases or decreases the bias voltage to compensate for variations in drum sensitivity that are induced by temperature changes in the drum cavity. At 30° Celcius (base temperature), no drum temperature compensation is performed.
  • Page 83 31 August 1989 Bias For ID Sensing In order to develop the ID sensor pattern consistently, the CPU applies a fixed base bias level to the development roller at the beginning of the first copy after power-up, and then once every ten copy cycles.
  • Page 84: Bias Control Circuit

    31 August 1989 5.6 BIAS CONTROL CIRCUIT The CPU sends a bias trigger signal through the TC/SC power pack to turn on the developer bias power pack. The main board also monitors the selected image density level and the copier rest time, and it sends a 4-bit bias output control signal to the bias power pack to control the bias output according to the image density level position and the copier’s rest time.

    31 August 1989 6. TONER DENSITY DETECTION AND TONER SUPPLY 6.1 TONER SUPPLY The toner supply drive gear [A] turns when the development motor is on. The toner supply clutch [B] applies the rotation from the toner supply drive gear to the toner supply roller gear [C], which drives the agitator gear [D].
  • Page 87: Bottle Drive Mechanism

    31 August 1989 6.2 BOTTLE DRIVE MECHANISM For easy access, the toner bottle is just inside the front cover. The bottle is positioned horizontally. The bottle drive mechanism transports toner from the bottle to the toner tank. A worm gear [A] on the front end of the toner supply roller [B] drives this mechanism.
  • Page 88: Toner Density Detection

    31 August 1989 6.3 TONER DENSITY DETECTION E: Full Erase F: ID Check G: Edge Erase (copy cycle) H: Low Toner Condition I: Enough Toner Condition J: Sensor Pattern Image The main CPU checks the image density of the sensor pattern at the beginning of the first copy cycle (after the main switch is turned on) and at every tenth copy cycle.
  • Page 89: Toner Density Control

    31 August 1989 6.4 TONER DENSITY CONTROL The image density sensor checks the density of the sensor pattern image once every 10 copy cycles. The CPU receives two voltage values directly from the sensor: the value for the bare drum (Vsg) and the value for the sensor pattern image (Vsp). These two values are then compared to determine whether or not more toner should be added.
  • Page 90: Toner Supply Amount

    31 August 1989 6.5 TONER SUPPLY AMOUNT This copier has two different ways of controlling the amount of toner supplied. Normally, the detect supply mode system is used to control toner supply. However, a fixed supply system can also be selected using SP #30. SP #30 Toner supply mode Detect...
  • Page 91 31 August 1989 Detect Supply Mode In the detect supply mode (SP#30 set to zero), when a low toner image density condition is detected (Vsp > 1/8 Vsg), toner is supplied during each copy cycle for the next ten copies as determined by SP #32 (toner supply amount -- fixed and detect modes).
  • Page 92: Toner End Detection

    31 August 1989 6.6 TONER END DETECTION Sufficient Toner Condition: The toner end detection mechanism actuates the toner end sensor [A] when the toner tank is almost empty (60 to 100 grams remaining). In the first figure, there is enough toner in the toner tank. The toner resists the movement of the toner agitator [B] and the drive spring [C] stretches.
  • Page 93: Toner Overflow Sensor Circuit

    31 August 1989 6.7 TONER OVERFLOW SENSOR CIRCUIT The toner overflow sensor signals the CPU when the toner collection bottle is full. A tiny tuning fork is used as the sensing element for the toner overflow sensor. This tuning fork is a damping element in a multivibrator circuit. As long as there is nothing in contact with the tuning fork, the oscillating frequency of the circuit stays LOW and the transistor stays off.
  • Page 94: Pre-Transfer Lamp (Ptl)

    31 August 1989 7. IMAGE TRANSFER AND PAPER SEPARATION 7.1 PRE-TRANSFER LAMP (PTL) After the latent image is developed but before the image is transferred to the copy paper, the drum surface is illuminated by the pre-transfer lamp [A]. This illumination reduces the positive potential on the drum surface.
  • Page 95: Image Transfer

    31 August 1989 7.2 IMAGE TRANSFER The registration rollers [A] feed the copy paper through the transfer entrance guide to the transfer section. A high positive voltage is applied to the transfer corona wire [B], and the corona wire generates positive ions. These positive ions are applied to the reverse side of the paper, and the paper is electrostatically attracted to the drum surface.
  • Page 96 31 August 1989 Since the positive force applied to the reverse side of the paper by the transfer corona is much greater than the strength of the positive ions on the drum surface, A1 is greater than A3, and A2 is greater than A3. A1 >...
  • Page 97: Paper Separation

    31 August 1989 7.3 PAPER SEPARATION A1 > A2 > A3 –> Separation occurs After image transfer, the paper is fed to the separation section. This process separates the paper from the drum while holding the toner on the paper surface. Ac and dc currents are applied to the separation corona wire, and the corona wire generates ions.
  • Page 98: Transfer/Separation Corona Power Pack

    31 August 1989 7.4 TRANSFER/SEPARATION CORONA POWER PACK The power pack has a dc-to-dc converter and a dc-to-ac inverter. The dc-to-dc converter changes +24 volts (Vp) to 5.78 kilovolts dc for the transfer corona. The inverter changes +24 volts (Vp) to 6.2 kilovolts ac with a slight negative dc bias for the separation corona.
  • Page 99 31 August 1989 The separation corona current is not always constant. It has two levels--a lead edge level and the normal level.

    31 August 1989 7.5 PICK-OFF MECHANISM Touch-and-Release Mechanism The pick-off solenoid [A] energizes just after the registration rollers turn on. The pick-off lever [B] rotates counterclockwise (rear view) and pushes the pawl shaft pin [C]. The pawl shaft [D] then rotates clockwise and the pick-off pawls [E] touch the drum. The pawl springs [F] hold the pick-off pawls on the shaft and prevent them from touching the drum too strongly.

    31 August 1989 9. QUENCHING 9.1 OPERATION The pre-quenching corona (PQC) [A] applies a positive dc corona (5 kilovolts) to neutralize the negative charge remaining on the drum’s surface from the pre-cleaning corona. Simultaneously, the quenching lamp [B] neutralizes any remaining positive charge on the drum.
  • Page 110: Pre-Quenching Corona Circuit

    31 August 1989 9.2 PRE-QUENCHING CORONA CIRCUIT Circuit operation begins with the application of +24 volts to CN1-1 on the PQC power pack. This is the power source for the high-voltage (dc 5 kilovolts) corona. When the Start key is pressed, the CPU energizes the PQC power pack through the TC/SC power pack by supplying a LOW at CN101-B20.

    31 August 1989 10.2 LIFT MECHANISM AND PAPER END DETECTION When the cassette is inserted into the copier, the cassette actuator pin [A] is pushed down by the cassette. The lift motor unit then mechanically pivots clockwise at point [B] so that the lift gear [C] engages with the sector gear [D].
  • Page 113 31 August 1989 As paper is fed into the copier, the level of the paper stack gets lower. If the level becomes too low, the lift sensor is actuated and the CPU energizes the lift motor until the top sheet raises the pick-up roller to deactuate the lift sensor again.
  • Page 114: Roller Function

    31 August 1989 10.3 ROLLER FUNCTION This copier uses an FRR (Feed + Reverse Roller) paper feed system with three rollers. Pick-up Roller The pick-up roller [A] rests on the paper stack until the start key is pressed.. A few moments after the Start key is pressed, the pick-up roller starts to rotate and feeds the top sheet between the feed roller [B] and the separation roller [C].
  • Page 115 31 August 1989 The direction that the separation roller [A] turns depends on the frictional forces acting on it. The slip clutch applies a constant clockwise force (F2). When there is a single sheet of paper being driven between the rollers, the force of friction between the feed roller [B] and the paper (F1) is greater than F2.

    31 August 1989 10.4 SLIP CLUTCH MECHANISM D: Separation Roller E: Slip Clutch Cover The slip clutch has two hubs connected by a drive spring [A]. The spring grips the output hub [B] tightly and grips the input hub [C] loosely. It will slip if the resistance to rotation is too great.
  • Page 117: Paper Feed Drive

    31 August 1989 10.5 PAPER FEED DRIVE Roller Drive Mechanism The pick-up rollers [A] and the feed rollers [B] are driven by the paper feed motor [C]. The main board sends a paper feed signal to the paper feed control board, which then energizes the paper feed clutch [D].
  • Page 118 31 August 1989 Pick-up Roller Up/Down Movement The pick-up roller is raised by a solenoid. When the leading edge of the paper passes between the feed roller and separation roller, the CPU energizes the solenoid and the pick-up roller is lifted out of the paper path. This copier has three pick-up solenoids. Two solenoids [A] are used for the first and second cassette paper feed.
  • Page 119: Manual Feed

    31 August 1989 10.6 MANUAL FEED In manual feed mode, up to 20 sheets (normal weight) can be loaded on the manual feed table and fed into the copier without a cassette. Manual feed mode uses the rollers of the first feed station.

    31 August 1989 12.3 ENTRANCE GUIDE The entrance guide [A] for this machine is adjustable for thick or thin paper. With thin paper, set the entrance guide in the upper position. This slightly lengthens the paper path which prevents the paper from creasing in the fusing unit. With thick paper, set the entrance guide in the lower position.
  • Page 130: Oil Supply And Cleaning

    31 August 1989 12.4 OIL SUPPLY AND CLEANING Silicone oil is applied to the hot roller to prevent toner and paper from sticking to the hot roller, to reduce paper curl, and to clean the roller. A small one-way-valve pump moves the oil from the oil tank [A] (capacity 360 cc) to the oil supply pad [B].
  • Page 131: Oil End Sensor

    31 August 1989 12.5 OIL END SENSOR Oil end detection is based on the difference between the index of refraction of air and the index of refraction of silicone oil. The index of refraction of silicone oil (1.40) is very near that of the sensor casing (1.49); so, the oil-casing interface has a very large critical angle.

  • Page 133: Fusing Control

    31 August 1989 12.7 FUSING CONTROL The main board monitors the fusing temperature through the fusing thermistor to control the fusing temperature. It also uses the zero-cross signal generated by the ac drive PCB to accurately control the applied power. Normally, the voltage applied to the lamp is a full ac waveform.
  • Page 134 31 August 1989 Phase Control In the phase control mode, the fusing lamp receives ac power constantly. The amount of power is regulated by the width of the trigger pulse. The wider the trigger pulse (C1), the more ac power the lamp receives (D1); therefore, the temperature increases. As the temperature rises, the LOW trigger pulse becomes narrower (C2) and less power is applied to the lamp (D2);...

  • Page 297: Overview

    31 August 1989 4. OVERVIEW This unit adds two additional universal cassettes (500 sheets each), which are the third and fourth cassettes, to the copier. Both the third and fourth paper feed stations have an FRR (Feed and reverse roller) mechanism which is similar to the feed system of the copier, except for the following items.
  • Page 298: Paper Feed Clutch On Timing

    31 August 1989 5. PAPER FEED CLUTCH ON TIMING The paper path length from each paper feed station to the registration rollers is different. For this reason, the paper feed magnetic clutch on timing for each paper feed station is different.
  • Page 299: Paper Size And Volume Sensors

    31 August 1989 6. PAPER SIZE AND VOLUME SENSORS The CPU sends separate scan pulses (SCAN 3, 4) to the corresponding sensors of the cassette bank. The output of this group of sensors for all cassettes can be monitored by one data bus because the scan pulses are sequential, allowing the CPU to determine which cassette information is being received.

  • Page 310: Basic Operation

    31 August 1989 2. BASIC OPERATION 2.1 INTERFACE The DF has its own CPU which controls all of the DF functions. The DF CPU communicates with the copier through an interface board and serial interface bus. Fiber optics are used for the serial interface bus because they are unaffected by electrical noise.
  • Page 311: Single-Sided Original Feed

    31 August 1989 2.2 SINGLE-SIDED ORIGINAL FEED - Feed-in - The DF CPU energizes the stopper and pick-up solenoids, and then turns on the feed-in motor. The feed [A] and friction rollers [B] separate and feed an original to the registration rollers [C].
  • Page 312: Two-Sided Original Feed

    31 August 1989 2.3 TWO-SIDED ORIGINAL FEED - Feed-in - The operation in this mode is exactly the same as that in the single-sided original feed mode until the registration solenoid turns on. The original is then inverted in order to copy the reverse side of the original first.
  • Page 313: Feed-In Unit Mechanism

    31 August 1989 3. FEED-IN UNIT MECHANISM After an original is inserted into the feed-in unit and the Start key is pressed, the DF CPU energizes the pick-up solenoid [A]. This causes the pick-up roller [B] to drop onto the original(s).
  • Page 314: Separation Mechanism

    31 August 1989 4. SEPARATION MECHANISM µ1 - Coefficient of friction between the feed rollers [A] and the original [B]. µ2 - Coefficient of friction between the friction rollers [C] and the original. µ3 - Coefficient of friction between originals. This model uses an FFR (Feed and Friction Roller) original feed system with three sets of rollers (feed, friction and pick-up rollers).
  • Page 315: Misfeed Prevention

    31 August 1989 5. MISFEED PREVENTION The front side of the friction roller [A] is attached to the misfeed prevention lever [B] via a one-way clutch. When the leading edge of an original [C] first contacts the feed [D] and friction rollers, the friction roller is stationary.
  • Page 316: Wear Prevention

    31 August 1989 6. WEAR PREVENTION The rear side of the feed roller shaft drive gear has an eccentric cam [A]. This cam contacts the wear prevention lever [B] which is attached via a one-way clutch to the friction roller shaft [C].
  • Page 317: Friction Roller Release Mechanism

    31 August 1989 7. FRICTION ROLLER RELEASE MECHANISM In the ADF mode, when the original activates the original entrance sensor [A], the DF CPU energizes the roller release solenoid [B]. This action rotates the roller release cam shaft [C], which has an eccentric cam [D] on each end, to decrease the overlap of the feed [E] and friction rollers [F].
  • Page 318: Registration

    31 August 1989 8. REGISTRATION NOTE: In the following discussion, ADF timing is in parentheses. The DF CPU stops the feed-in motor 25 milliseconds after the leading edge of the original activates the original entrance sensor [A]. The forward momentum of the original causes it to align against the registration roller [B] (skew correction).
  • Page 319: Inverter Mechanism

    31 August 1989 9. INVERTER MECHANISM In the two-sided original mode, the belt drive motor reverses 75 milliseconds after the leading edge of the original passes the exit sensor; however, the feed-out motor [A] continues to turn forward. Since the friction between the turn roller [B] and the original is greater than the friction between the DF belt [C] and the original, the original continues to move forward through the inverter mechanism.
  • Page 320: Feed-Out Mechanism

    31 August 1989 10. FEED-OUT MECHANISM When the DF CPU receives the feed-out signal, it energizes the belt drive and feed-out [A] motors. The feed-out motor drives the exit rollers [B] through the timing belt [C]. The DF CPU slows down the feed-out motor when the trailing edge of the original passes the exit sensor.
  • Page 321: Lift Mechanism

    31 August 1989 11. LIFT MECHANISM The lift spring [A] resists the weight of the belt unit, making it easier to lift the belt unit. When the belt unit is lifted, the detent arm [6] turns on the lift switch. At the same time, the DF CPU sends a signal to the copier CPU.
  • Page 322: Misfeed Check

    31 August 1989 12. MISFEED CHECK During single-sided mode, three sensors check for misfeeds: the original entrance sensor [A], registration sensor [B], and exit sensor [C]. After the feed-in motor turns on, the original activates the original entrance sensor. The DF CPU checks to see if the original entrance sensor has been activated (original entrance sensor ON check) 475 ms after the feed-in motor turns on.
  • Page 323 31 August 1989 During two-sided original mode, three sensors detect misfeeds. The ON checks for the original entrance sensor and the registration sensor are the same as when in single-sided mode. The DF CPU checks if the original entrance sensor has been deactivated 1,250 milliseconds after the registration sensor is activated (original sensor OFF check).

    31 August 1989 6. BASIC OPERATION -lntroduction- Sorter operation begins when the Start key is depressed. At that time, the sorter drive motor turns on and the rollers start turning. The sorter has two paper transport speeds. When paper first enters the sorter, it is transported at the “slow speed”...
  • Page 432 31 August 1989 If the mode is not changed, the sorter will continue in this way, sending all copies from a single run to one bin and dropping down one bin each run until there are copies in all 15 bins. Upon completion of the copy run to the 15th bin, copying will stop and the guidance display will indicate that the sorter is full.
  • Page 433 31 August 1989 -Interrupt Mode- If the Interrupt key is depressed during a multicopy run, the sorter continues to place copies in the correct bins until that copy run is finished. Which bin the copies go to depends on the mode: sort, stack, or clear.
  • Page 434 31 August 1989 -Control- The sorter has its own CPU which controls all the functions of the sorter. The sorter CPU communicates with the copier through a parallel interface bus. The sorter supplies 100 Vac to the transformer. The transformer changes this 100 Vac to 23 Vac and it is then supplied to the dc power supply unit.
  • Page 435: Functional And Electrical Description

    31 August 1989 7. FUNCTIONAL AND ELECTRICAL DESCRIPTION 7.1 Power Supply When the copier’s main power switch is turned on, the copier supplies 100 Vac to the sorter’s inner transformer. The transformer drops it to 23 Vac. This 23 Vac is changed to +24 V (Vs) through the rectifier and the voltage regulator IC (IC1) in the sorter power supply unit.
  • Page 436: Bin Gate Operation

    31 August 1989 7.2 Bin Gate Operation Each bin gate shaft [A] is individually controlled by a solenoid. Normally, the bin gates [B] are held out of the paper path by the return spring [C]. To feed paper into a bin, the sorter CPU energizes the appropriate solenoid. The solenoid plunger [D] then rotates the bin gate lever [E] and opens the gate out into the paper path.
