Page 27: Watchdog (Cpu Overrun Monitor) Function
1173SBM0500A WATCHDOG (CPU OVERRUN MONITOR) FUNCTION The watchdog function monitors whether any of the CPUs mounted in the copier overrun. If this function detects that a CPU overruns, the copier automatically resets the CPU, thereby restarting the logic circuit and mechanism. Even if a copier CPU operates erratically due to electrical noise, therefore, the copier is able to recover from the faulty condition so that the number of visits made by the Technical Representative for CPU overrun can be minimized.
Page 28: Watchdog Function Post-Processing
1173SBM0502A 5-2. Watchdog Function Post-Processing The following processing is performed if a faulty condition is detected in the CPU. When the copier CPU is found faulty: • All CPUs including those of the options are reset and the system is restarted. If the CPU is found faulty during a copy cycle, the system attempts to feed all sheets of paper out of the copier before resetting.
Page 29: Malfunction Bypass Function
1173SBM0600A MALFUNCTION BYPASS FUNCTION • When a malfunction occurs in the copier, the malfunction bypass function permits the copier to continue operating if that malfunction is one of the predefined candidates for an isolated malfunction and if it will not affect the current copying operation. But, if an iso- lated malfunction occurs anytime during the actual copy cycle, the copier considers it a normal malfunction.
Page 30: Image Stabilization System
1173SBM0700A IMAGE STABILIZATION SYSTEM The following image stabilization controls are provided to ensure stabilized copy image. Item Quality Purpose Control Initial Setting Image density, To make initial settings of Sets the initial values for gradation grid voltage (Vg), optimum grid voltage correction, opti- Exposure Lamp voltage, mum Exposure Lamp volt- and AE Sensor gain.
Page 31: Aldc Sensor
1173SBM0701A 7-1. AlDC Sensor To provide image stabilization control, this copier has the AlDC Sensor fitted to the Clean- ing Unit of the Imaging Unit. The sensor is used to detect the toner density and background level on the PC Drum. Operation 1.
Page 32: Image Stabilization Control Processing Timing
1173SBM0702A 7-2. Image Stabilization Control Processing Timing • The image stabilization controls use the AIDC Sensor and AE Sensor as the basis for performing the following four major types of processing. • The grid voltage, T/C, and optimum Exposure Lamp corrections are not, however, made if T/C falls outside the range of 4% to 8% at adjustment.

1173SBM0703A 7-3. Details of Image Stabilization Controls 1. AIDC Sensor adjustment 3. Optimum Exposure Lamp voltage 2. Grid voltage and T/C correction correction 4. AE Sensor gain adjustment • The following are the details of each image stabilization control. 1-1. AIDC Sensor coarse adjustment This adjustment represents a coarse adjustment of the AIDC Sensor when the ordinary control of only the LED current cannot cover part-to-part variations in the AIDC Sensor (installation, circuit, deterioration, etc.).
Page 34 <Relation with Image Density> The “Image Exposure” function of “Tech. Rep. Choice” available from the Tech. Rep. mode enables fine-adjustments of the grid voltage (solid-black image density) to be made. It specifies how many volts the optimum grid voltage determined by the image stabilization control is to be increased or decreased.
Page 35: Imaging Unit
1173SBM0800A IMAGING UNIT This copier is equipped with an Imaging Unit, or IU, which integrates a PC Drum, PC Drum Charge Corona, Developing Unit, Cleaning Unit, and Toner Recycling mechanism into one assembly. The Unit also includes the Upper Synchronizing Roller which facilitates clearing of a paper misfeed.

Page 37: Pc Drum
1173SBM0900A PC DRUM The photoconductive drum used in this copier is the organic photoconductor (OPC) type. The drum is made up of two distinct, semiconductive materials on an aluminum alloy base. The outer of the two layers is called the Charge Transport Layer (CTL), while the inner layer is called the Charge Generating Layer (CGL).
Page 38: Drum Charging
1173SBM1000A DRUM CHARGING The PC Drum Charge Corona has a Scorotron grid to deposit a negative DC charge evenly across the surface of the PC Drum. The grid voltage (VG) applied to the grid mesh is selected between –550V (initial value, variable according to image stabilization controls) in the normal mode and the value in the normal mode +90V in the Photo mode by the Con- stant-Voltage Circuit in the High Voltage Unit.
Page 39: Image Erase Lamp
1173SBM1100A IMAGE ERASE LAMP To prevent a black band from occurring across both the leading and trailing edges, and along the front and rear edges, of the electrostatic latent image, 38 LEDs of the Image Erase Lamp are turned ON before development takes place, thereby reducing to a mini- mum the unnecessary potential on the surface of the PC Drum.

Page 43: Optical Section
1173SBM1200A OPTICAL SECTION As the Scanner is moved by the Scanner Motor, the light from the Exposure Lamp is reflected off the original and guided through the four Mirrors onto the surface of the PC Drum to form the electrostatic latent image. The image is enlarged or reduced as necessary by changing the position of the Lens and 4th Mirror and varying the angle of the 4th Mirror.
Page 44: 12-1.Exposure Lamp
1173SBM1201A 12-1. Exposure Lamp An AC halogen lamp is used as an Exposure Lamp. As the exposure level is adjusted on the control panel, the duty ratio of the pulse of AVR Remote from the Master Board changes to increase or decrease the Exposure Lamp volt- age, thereby changing the image density.
Page 45: Exposure Lamp
1173SBM1202A 12-2. AE Sensor In the Auto Exposure Mode, the AE Sensor on AE Sensor Board measures the intensity of the light reflected off the original, by sampling the black/white ratio of a 210-mm-wide area of the original being measured. According to this measurement, the Exposure Lamp volt- age is automatically increased or decreased so that copies of consistent quality are pro- duced.
Page 46: 12-3.Lamp Reflectors
1173SBM1203A 12-3. Lamp Reflectors The Main Reflector ensures that light from the Exposure Lamp exposes all areas of the original. The Auxiliary Reflector reflects light onto the areas that the Exposure Lamp cannot illuminate when an original that does not lie flat on the Original Glass (such as a book) is being used.
Page 47: 12-5.Scanner And 2Nd/3Rd Mirror Carriage Movement
1173SBM1205A 12-5. Scanner and 2nd/3rd Mirror Carriage Movement The Scanner and 2nd/3rd Mirrors Carriage are moved by the Scanner Drive Cable fitted in the rear side of the copier. The Cable is driven by the Scanner Motor. Both the Scanner and 2nd/3rd Mirrors Carriage slide along the Scanner Shaft at the rear side.
Page 48 The Scanner starts the scan motion when a Scan signal is output from the Master Board. At the start of a scan motion and other heavy load conditions, the Scanner Motor requires a large amount of current. The Current 1 or 2 signal from the Motor Drive Board is selected accordingly to vary the amount of current supplied to the Scanner Motor.
Page 49: 12-6.4Th Mirror Movement
1173SBM1206A 12-6. 4th Mirror Movement The 4th Mirror is moved to vary the conjugate distance for a particular zoom ratio by driving the rack-and-pinion gears at the front and rear ends of the mirror using the Mirror Motor (stepping motor). The Levers of the Holder to which the Mirror is mounted slide along a tilted rail to change the Mirror angle.
Page 50: 12-7.Lens Movement
1173SBM1207A 12-7. Lens Movement The Lens is moved by the Lens Drive Cable which is driven by the Lens Motor (stepping motor). The motor drive pulses sent from the Motor Drive Board drive the Lens Motor to move the Lens a given distance, corresponding to the zoom ratio, from the reference posi- tion determined by Lens Reference Position Sensor.
Page 51: Original Size Detecting Sensors
1173SBM1300A ORIGINAL SIZE DETECTING SENSORS The five sensors fixed in the optical section receive the light reflected off the original to determine the size of the original in the Auto Paper and Auto Size mode. (The image den- sity of the original, or OD, that can be detected is 0.6 or less.) 1173SBM1301A 13-1.

Page 53: 13-4.Size Detection
1173SBM1304A 13-4. Size Detection • Original Size Detecting Board reads the output data provided by the original size detect- ing sensors. By comparing the data from each sensor with the threshold level, it deter- mines whether there is an original placed on the Original Glass. Original Size Detecting Board then determines the size of the original according to the combination of the data.

Page 55: Original Cover Angle Detection
1173SBM1306A 13-6. Original Cover Angle Detection The Original Cover Detecting Sensor detects the angle of the Original Cover as it is raised. The following control is provided. Original Cover raised to an angle of 15° or more: The size of the original is read by the Original Size Detecting Sensors. Original Cover raised to an angle of less than 15°: When the Original Cover Detecting Sensor is activated, the master CPU of Master Board latches the original size data transmitted by Original Size Detecting Board.
Page 56: Development
1173SBM1400A DEVELOPMENT The Developing Unit built into the Imaging Unit performs the following functions: • Mixes the toner and carrier well to ensure that a sufficient amount of toner is positively charged. • Detects the toner-to-carrier ratio of the developer by means of the ATDC Sensor and replenishes the supply of toner as necessary.
Page 57: 14-1.Atdc Sensor
1173SBM1401A 14-1. ATDC Sensor The copier compares the toner-to-carrier ratio (T/C) of the developer in the Developer Mix- ing Chamber detected by ATDC Sensor during a copy cycle with the reference ratio (6%) and, if it finds a lower ratio than the reference, replenishes the supply of toner. The standard output voltage of the ATDC Sensor for the reference T/C (6%) is 2.5V.
Page 58 Toner Empty Detection The copier has no toner empty detecting sensor and, instead, the ATDC Sensor performs that function. The ATDC Sensor checks the toner-to-carrier ratio and, if it reads a T/C ratio lower than the reference level for 37 copies and, further, if it next reads a ratio 1% lower than the reference level, this is a toner-empty condition.
Page 59: 14-2.Magnet Roller
1173SBM1402A 14-2. Magnet Roller The Magnet Roller of the Sleeve/Magnet Roller of this copier has the following magnetic characteristics. Part of pole S2 before the principal N1 pole (i.e., the area marked as S2b in the Fig. below) provides a very weak magnetic force. If developer is compacted and clogs at the Doctor Blade and, as a result, part of the surface of the Sleeve/Magnet Roller is not covered with developer, the nearby developer around S2b goes to those uncovered areas because of the weak magnetic force.
Page 60: 14-3.Developing Bias
1173SBM1403A 14-3. Developing Bias A negative voltage (Vb = Developing Bias voltage) is applied to the Sleeve Roller to prevent a foggy background on the copy. The amount of toner attracted onto the surface of the PC Drum depends on how much lower the PC Drum surface potential (Vi) is than Vb (i.e., the potential difference).
Page 61: 14-4.Doctor Blade
1173SBM1404A 14-4. Doctor Blade The Doctor Blade installed over the Sleeve/Magnet Roller regulates the height of the devel- oper brush on the surface of the Sleeve Roller. The Blade is perpendicular to the direction of movement of the Magnet Roller to minimize variations in the distance between the Doc- tor Blade and Magnet Roller as the Magnet Roller moves.

Paper Take-Up Retry Control To minimize the occurrence of a paper misfeed due to a slippery paper Take-Up Roll, the Manual Feed Paper Take-Up Clutch is kept deenergized for a given period of time before it is energized again, if a sheet of paper fails to reach the Transport Roller Sensor even after the lapse of a given period of time after the clutch has first been energized.
Page 83: 17-3.Paper Separating Mechanism
1173SBM1703A 17-3. Paper Separating Mechanism The paper separating mechanism ensures that only the top sheet of paper is fed in by sep- arating the second sheet of paper from the top one. This is accomplished by the Torque Limiter fitted to the Separator Roll shaft which stops the Separator Roll when there is a change in friction between the Feed and Separator Rolls.
Page 84: Synchronizing Rollers
1173SBM1800A SYNCHRONIZING ROLLERS The Synchronizing Rollers, operating in phase with the Scanner scan motion and paper feeding, synchronize the leading edge of the copy paper accurately with the leading edge of the toner image on the PC Drum. The Upper Synchronizing Roller is a metal roller covered with a polyvinyl chloride tubing, while the Lower one is a rubber roller.
Page 85: 18-1.Upper Synchronizing Roller Positioning
1173SBM1801A 18-1. Upper Synchronizing Roller Positioning Since the Upper Synchronizing Roller is fitted to the Imaging Unit, it must be correctly posi- tioned with reference to the Lower Synchronizing Roller when the Upper Half of the copier is swung down into the locked position. For this purpose, slots are cut in the lower copier frame and the Bushings of the Upper Synchronizing Roller fit into these slots.

Page 87: Image Transfer And Paper Separation
1173SBM1900A IMAGE TRANSFER AND PAPER SEPARATION Image Transfer The Image Transfer Corona applies a DC negative corona emission to the underside of the paper thereby attracting the positively charged toner onto the surface of the paper to form a visible, developed image of the original. The Corona Unit is provided with a Corona Wire cleaning mechanism: the operator has only to pull out the Lever on which the Cleaner is mounted from the front of the copier, which cleans the Wire.

Page 90: Paper Separator Fingers
1173SBM2100A PAPER SEPARATOR FINGERS After image transfer, an AC corona emission is applied to the underside of the paper by the Paper Separator Corona to neutralize the paper so that it can be easily separated from the PC Drum. To further ensure that the paper is positively separated from the PC Drum, there are two Paper Separator Fingers attached to the Imaging Unit.

Page 94: Paper Transport
1173SBM2300A PAPER TRANSPORT After having gone through the image transfer and paper separation processes, the paper is then transported to the Fusing Unit by the Suction Belts of the Suction Deck driven directly by the Main Drive Motor. The Suction Fan Motor draws the paper onto the turning Suction Belts for positive transport of the paper.
Page 95: Fusing Unit
1173SBM2400A FUSING UNIT The Upper Fusing Roller and Lower Fusing Roller together apply heat and pressure to the toner and paper to permanently fix the developed image to the paper. Drive for the Upper Fusing Roller is transmitted from the Main Drive Motor to the Upper Fusing Roller Drive Gear.
Page 96: 24-1.Fusing Temperature Control
1173SBM2401A 24-1. Fusing Temperature Control The Upper Fusing Roller is heated by a Fusing Heater Lamp which is an AC halogen lamp. Fusing Thermistor 1 and 2 installed on the Upper Fusing Roller help keep the optimum fus- ing temperature. The fusing temperature is normally controlled at 195°C.
Page 97: 24-2.Fusing Rollers Pressure Mechanism
<Fusing Temperature Control During Continuous Small-Size Paper Feeding> When a number of sheets of small-size paper are fed through the copier continuously, the temperature of the rear end of the Fusing Rollers tends to rise, resulting in high-tempera- ture offset occurring. Fusing Thermistor is installed at a location 278.5 mm from the posi- tion of paper passage registration.
Page 98: 24-3.Brush Roller/Cleaning Roller
1173SBM2403A 24-3. Brush Roller/Cleaning Roller • The Brush Roller is pressed up against the Upper Fusing Roller. It turns in the direction opposite that of the Upper Fusing Roller and, with its brush, removes toner and paper dust. • The Cleaning Roller is made up of an aluminum cylinder around which a high tempera- ture resistant paper based material is wound.
Page 99: Exit Unit
1173SBM2500A EXIT UNIT The Paper Exit Roller/Rolls feed the paper, to which the developed image has been fixed, out of the Fusing Unit to the Exit/Duplex Switching Unit. The Charge Neutralizing Brush touches the surface of the sheet of paper being fed out of the Fusing Unit to neutralize any static charge left on it.
Page 100: Exit/Duplex Switching Unit
1173SBM2600A EXIT/DUPLEX SWITCHING UNIT The Exit/Duplex Switching Unit has the following functions: • Transmits the copier drive to the Sorter/Staple Sorter. • Locks the Sorter/Staple Sorter in position. • Selects the paper path, either to the exit or to the Duplex Unit, when the copier is equipped with a Duplex Unit.
Page 101: Dehumidifying Switch (Option)
1173SBM2700A DEHUMIDIFYING SWITCH (OPTION) To prevent image transfer efficiency from being reduced due to damp paper in highly humid weather, Paper Dehumidifying Heater is installed on the base frame of the copier under the 2nd Drawer. A Drum Dehumidifying Heater is located under the Lower Synchronizing Roller to prevent the PC Drum from forming condensation.
Page 102: Cooling Fan
1173SBM2800A COOLING FAN Ozone produced by the PC Drum Charge Corona and Image Transfer/Paper Separator Coronas is drawn out of the copier by the Cooling Fan Motor and absorbed by the Ozone Filter. The Cooling Fan Motor is turned either at high or low speed. It turns at high speed while Main Drive Motor or PC Drive Motor is being energized.
Page 103: Optical Section Cooling Fan
1173SBM2900A OPTICAL SECTION COOLING FAN The Optical Section Cooling Fan Motor draws outside air into the copier and blows it against the Original Glass which is heated by the lit Exposure Lamp. The Filter at the intake port of the Fan prevents dust and dirt from entering the Optical Sec- tion of the copier.
