Page 23: Selenium Drum
1 Nov. '87 1. SELENIUM DRUM Selenium has the characteristics of: Being able to accept a high positive electrical charge in the dark. (The electrical resistance of selenium is high in the absence of light.) Dissipating the electrical charge when exposed to light. (The conductivity of selenium is greatly enhanced by exposure to light.) Losing electrical charge in direct proportion to the intensity of the light.
Page 24: Drum Charge
1 Nov. '87 DRUM CHARGE 1. OVERVIEW This copier uses a single wire corotron [A] and a selenium drum. The corona wire generates a corona of positive ions when a high positive voltage (+5.4 kilovolts) is applied by the CTB power pack [P2]. The selenium coat- a uniform positive charge (approximately 850 volts) as it rotates receives past the corona unit [B].
Page 25: Temperature Compensation
1 Nov. '87 2. TEMPERATURE COMPENSATION Corona Current Output Compensation (milliamperes) Drum Temperature (C) The charge carrying capacity of the selenium drum varies with temperature. The CTB power pack monitors the drum temperature through a thermistor (TH2), and automatically changes the charge corona voltage to compensate for temperature changes.
Page 26: Corona Wire Cleaner
1 Nov. '87 3. CORONA WIRE CLEANER The flow of air around the charge corona wire [A] may deposit paper dust or toner particles on the corona wire. These particles may interfere with charg- ing and cause low density bands on copies. The wire cleaner [B] allows the operator to correct this problem by simply pulling out and pushing in the corona unit.
Page 27: Charge Corona Circuit
1 Nov. '87 CHARGE CORONA CIRCUIT [ P C B I ] The circuit operation for the charge corona begins with the input of +24 volts to the CTB power pack [P2] at CN1 -1. This power supply is used for the high voltage corona, On normal copy cycles the charge corona turns on 1.65 seconds after the...

Page 29 1 Nov. '87 This model uses two magnetic clutches [A] to drive the scanners. The first scanner [B], which consists of the exposure lamp [C] and the first mirror, is connected to the scanner drive wire by the wire clamp [D]. The second scanner [E], which consists of the second and third mirrors, is con- nected to the scanner drive wire ‘by a movable pulley (the second scanner pulley [F]).

1 Nov. '87 4. EXPOSURE LAMP CONTROL The exposure lamp is controlled by thelamp control PCB [PCB2], which con- tains both the exposure lamp regulator circuit and the fusing lamp control cir- cuit. The main CPU sends the lamp trigger signal (LOW) from CNI 14-4 about 1 second after the Start key is pressed.

Page 33: Service Call Conditions
1 N o v . ' 8 7 `6. SERVICE CALL CONDITIONS - Code El - The CPU checks the original sensor approximately 1 second after the ex- posure lamp turns on. If the input from the sensor is less than 0.3 volt, the CPU stops the copier and displays El in the copy counter.
Page 34: Development
1 Nov. '87 DEVELOPMENT roller When the main motor turns on, the paddle roller [A] and development The paddle roller picks up developer in its paddles and start turning. transports it to the development roller. Internal permanent magnets in the development roller attract the developer to the development roller sleeve.
Page 35: Drive Mechanism
1 Nov. '87 2. DRIVE MECHANISM When the main motor turns, the rotation is transmitted from the development drive gear [A] to the development roller gear [B]. An idle gear [C] turns the paddle roller gear. A gear on the front end of the paddle roller shaft drives the agitator gear [D].
Page 36: Seals
1 Nov.'87 3. SEALS Several seals prevent toner from spilling out into the copier. The upper brush seal [A] prevents particles from scattering upward. The development unit side seals [B], are in contact with the drum ends (out of the image area) preventing toner scattering from the ends of the unit.
Page 37: Cross-Mixing
N o v . ' 8 7 4. CROSS-MIXING This copier uses a cross-mixing mechanism to keep the toner and developer evenly mixed and level in the development unit. It also helps agitate the devel- oper to prevent clumping and helps create the triboelectric charge. The developer on the turning development roller is split into two parts by the doctor blade [A].
Page 38: Image Density Control
1 Nov. 87 5. IMAGE DENSITY CONTROL Image density depends on two items: (1) the strength of the bias voltage ap- plied to the development roller sleeve, and (2) the strength of the voltage ap- plied to the exposure lamp. In this machine, the image density is controlled by varying the development roller bias.
Page 39 1 Nov. '87 By using this type of circuit, the bias output can be controlled using only one The strength of the bias depends on the ratio of T1 to T. The signal line. bias voltage increases linearly as T1 increases. (See the illustration.) - Manual Image Density Control - Notch Bias...
Page 40 1 N o v . ' 8 7 - Automatic Image Density Control - When automatic image density control is used, the bias depends on the background image density of the original, which is measured using the original ID sensor. In this mode the bias can take values between 250 volts and 500 volts.

Page 42: Development Set Switch
7. DEVELOPMENT SET SWITCH When the development unit is removed from the copier, the development set switch [A] turns off and U3 lights in the operation panel. When the develop- ment unit is properly set in the copier, the switch is actuated by a projection on the rear of the unit [B], and U3 turns off.
Page 43: Toner Density Detection
TONER DENSITY SUPPLY 1. TONER DENSITY DETECTION C: Drum D: Development Roller The CPU checks toner density by directly sensing the image density at the beginning of the first copy cycle after the main switch is turned on, and at every 10th copy after that.
Page 44 The image density sensor checks the density of the sensor pattern i m a g e 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 sen- sor pattern (Vsp).
Page 45: Toner Supply
3. TONER SUPPLY - Roller Drive Mechanism - The toner supply clutch gear [A] turns when the main motor is on. The trans- mission of this rotation to the toner supply drive gear [B] is controlled by the [C]. toner supply clutch When the toner supply clutch energizes, the toner supply drive gear starts gear [D] turning.
Page 46 - Toner Agitator Drive Mechanism - The toner agitator mechanism, which is contained in the toner cartridge, prevents toner from blocking. The toner agitator gear [A] is engaged with the toner supply roller gear through an idle gear [B]. Therefore, the toner agitator gear turns whenever the toner supply clutch is engaged.
Page 47: Toner End Detection
4. TONER END DETECTION The toner agitator gear [A] has a cam [B] (the toner end cam) on its inner surface, and it rotates only when toner is supplied. The cam follower on the end of the toner end lever [C] rides on the surface of the toner end cam (spring pressure).
Page 48: Image Transfer And Paper Separation
IMAGE TRANSFER AND PAPER SEPARATION 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. This prevents the toner particles from being re-attracted to the positively charged drum during the paper separation process.
Page 49: Paper Separation
1 Nov. ’87 3. PAPER SEPARATION After image transfer the copy must be separated from the drum. To break the attraction between the paper and the drum, the separation corona wire [D] applies an ac corona (5.0 kV, 500 Hz) to the reverse side of the paper. The stiffness and weight of the paper cause it to separate from the drum [E].

Page 51: Transfer/Separation Corona Circuits
1 NOV. ’87 5. TRANSFER/SEPARATION CORONA CIRCUITS The main PCB [PCBI ] powers the CTB power pack by providing +24 volts at CN 114-8 and powers the separation power pack with +24 volts at CN 109- 8. To actuate the transfer and separation coronas, the CPU provides a LOW at CNI 14-2 and CN1 09-2 respectively.

Page 54 1 NOV. ’87 3. CLEANING BLADE MECHANISM The cleaning pressure mechanism is shown above. When the cleaning turns the cleaning solenoid lever [B] solenoid [A] is energized, counterclockwise (rear view). The cleaning blade lever [C] is pressed by the cleaning solenoid lever [B], and turns counterclockwise.
Page 55: Toner Overflow Detection
4. TONER OVERFLOW DETECTION The toner overflow detection mechanism stops copier operation when the used toner tank gets full. The capacity of the used toner tank is about 350 grams. When the tank gets full, the pressure of the used toner pushes up movable plate [A] mounted in the top of the used toner tank.
Page 56: Pick-Off Mechanism
5. PICK-OFF MECHANISM When the cleaning pawl lever pressed unit is inserted in the copier, the [A] is by the rear side plate of the copier and the rear portion of each pick-off pawl [B] drops into the groove of the pawl lever (due to its weight). The tip of the pawl goes up and contacts the drum.
Page 57 1 Nov. ’87 QUENCHING In preparation for the next copy cycle, light from the quenching lamp [A] neu- tralizes any charge remaining on the drum [B]. The neon lamp used for quenching is the same as the pre-transfer lamp (PTL) [C]. The circuit is the same as that of the PTL and the lamps are inter- changeable.
Page 58 1 Nov. ’87 PAPER FEED AND REGISTRATION 1. OVERVIEW Paper feeds from either the cassette [A] or from the manual feed table [B] The capacity of the cassette is 250 sheets, and up to 50 sheets can be set at once on the manual feed table. This copier uses three rollers for paper feed: a pick-up roller [C], a feed roller [D], and a reverse roller [E].
Page 59 1 Nov. ’87 2. ROLLER FUNCTION This copier uses an utilizes three rollers. - Pick-up Roller - The pick-up roller [A] is not in contact with the paper stack before it starts feeding paper. Shortely after the Start key is pressed, the pick-up roller drops down and feeds the top sheet between the feed [B] and the reverse rollers [C].
Page 60 forces The direction that the reverse roller [A] turns depends on the frictional acting on it. The slip clutch applies a constant clockwise force (F1 ). 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 (F2) is greater than F1.
Page 61: Slip Clutch Mechanism
1 Nov. ‘87 3. SLIP CLUTCH MECHANISM Reverse Roller Slip Clutch Cover The slip clutch consists of 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 62 1 .Nov. '87 ROLLER DRIVE MECHANISM The mechanism shown above drives the feed rollers. Main motor rotation goes to the paper feed drive gear [A] via the timing belt and an idle gear. The paper feed drive gear turns the reverse roller drive gear [B].
Page 63 - Cam Rotation Mechanism - The paper feed drive gear [A] turns while the main motor is on. However, feed solenoid [SOL1 ] the paper feed [B] does not turn while the paper is off because the clutch pawl [C] is engaged with the sleeve of the paper feed clutch [D], which is a spring clutch.
Page 64 the cassette actuator lever [A] When the cassette is inserted into the copier paper lift clutch unit [B] then is pushed clockwise by the cassette. moves down and the paper lift gear [C] engages with the sector gear [D]. Under the following conditions, the CPU checks the paper lift sensor to see if the paper is at the feed position.
Page 65 1 Nov. ’87 6. PAPER END DETECTION When the cassette runs out of paper, the paper end feeler [A] drops through bottom plate. As it drops, the paper end sensor [B] slot in the cassette’s is actuated by the feeler. The paper end sensor then sends a HIGH signal to CN117-7 of the main PCB.

Page 67 1 Nov. ’87 8. MANUAL FEED The manual feed mode allows multi-feeding without a cassette. (Maximum paper quantity is 50 sheets of normal weight paper.) This is accomplished by the manual feed table. When the manual feed table [A] is opened, the manual feed pIate [B] rotates down and becomes an extension of the manual feed table.
Page 68: Paper Transport
1 Nov. ’87 PAPER TRANSPORT 1. OVERVIEW The copy paper rides on the transport beIts [A] to the fusing unit [B]. A vacuum fan [C] holds the paper firmly against the belts so that there is enough friction between the paper and the belts for smooth transportation.
Page 69 1 Nov. ’87 2. BELT DRIVE MECHANISM When the main motor is on, an idle gear [A] turns the release gear [B]. The release gear turns the rear transport gear [C], which is mounted on the transport belt drive shaft [D]. When the transport unit release lever is turned down, the release gear dis- engages from the idle gear, preventing operation.
Page 70: Image Fusing And Paper Exit
IMAGE FUSING AND PAPER EXIT The image is fused to the copy paper by two fusing rollers which apply heat and pressure. The hot roller [A] is made of teflon and the pressure roller [B] is made of silicone rubber. Pressure is constantly applied between the rollers.
Page 71 1 Nov. ’87 2. ROLLER DRIVE MECHANISM The main motor gear [A] transfers the rotation to the rear hot roller gear [B] gears as shown above. The pressure roller turns through a series of idle [D] is The upper exit roller gear to the friction of the hot roller [C].
Page 72 1 Nov. ’87 3. OIL SUPPLY AND CLEANING Silicone oil is applied to the hot roller to help prevent toner and paper from sticking to the hot roller, to reduce paper curl, and to help in roller cleaning. A small one-way valve pump moves the oil from the oil tank [A] (capacity oil sump [B].
Page 73 1 Nov. ’87 4. 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 [A] (1.40) is very near that of the sensor casing (1.49);...
Page 74 1 NOV. ’87 PAPER EXIT ASSEMBLY paper exit assembly includes the hot roller strippers [A], the exit guides [B] 1 the exit sensor [C], the exit rollers, and the antistatic brush. hot roller strippers prevent copy paper from wrapping around the hot roller.
Page 75 1 Nov, ;87 6. FUSING CONTROL Above is a schematic of the fusing lamp control circuit. The circuit has both ac and dc components, which are coupled through a photocoupler. - Fusing Lamp ON/OFF - To turn on the fusing lamp, the CPU supplies a at CN114-6.

Page 77: Service Call Condition
1 Nov. ’87 7. SERVICE CALL CONDITION - Code E5 - The following three conditions will cause the CPU to display E5 and prevent copier operation. The hot roller temperature does not increase at least 2 degrees within 10 seconds after the power is turned on. The most probable cause is an open thermistor circuit.

Page 80 . ’87 3. MISFEED CHECK TIMING The first jam check (registration sensor ON check) is 299 pulses after the paper feed solenoid turns on. If the paper has not arrived at the registration sensor by this time, the CPU determines that there has been a misfeed. The counter for the second jam check (the exit sensor ON check) starts when the registration clutch turns on.
Page 81 1 .Non ‘87 4. DATA BACK-UP The main board has a back-up circuit. If the user opens the front cover to clear misfed paper or to add toner/siIicone oil, the back-up system works to prevent any data from being lost due to power loss.
