Chapter 4 Disassembly / Assembly 4.1 Preface

4.1 Preface NOTE When working on an item which is controlled as a spare part but the procedure therefore is not described, observe carefully how the part is attached before removing the item.

NOTE As a general rule, optional items are assumed to be removed from the equipment. However, you may work with optional items attached if it does not disturb your work.

Safety Critical Component (SCC) Control of the safety of components that are designated Safety Critical Components shall conform to Fuji Xerox Co. Ltdstipulated rules and regulations on Safety Critical Components. As to replacement of any component designated SCC, the complete component unit must be replaced. It must never be disassembled or no individual internal parts of it must be replaced. Installation of any part other than the ones designated by Fuji Xerox Co. Ltd. shall be strictly prohibited because it cannot be guaranteed in quality and safety. Important Information Stored Component (ISC) Important Information Stored Components store customers' important information they have entered after machine installation. When replacing Important Information Stored Components, you must replace and discard them, following the procedure described in Chapter 4 Adjustments. Take care never to let customer information leak out.

4.1.1 Before starting service work  Start the procedure after turning off the power and removing the power cord from the outlet.  When performing the service operation around the FUSING UNIT, ensure that FUSING UNIT and its surrounding area have cooled down sufficiently.  Pay sufficient attention to the parts during the procedure because they may be broken or may not perform their functions properly if unreasonable force is applied.  Since various types of screws are used, ensure that the right screws are used in their right positions. Use special caution not to confuse the screws for plastic and the ones for sheet metal, because using the wrong type of screw may result in damage to the screw threads or other troubles.  Wear a wristband or the like as far as possible to remove static electricity of the human body.

10.1 Printing Process 10.1.1 Summary of Printing Process This device is an LED-based full-color xerographic printer operating on a tandem printing system that has four colorspecific drum/developer sets for yellow, magenta, cyan, and black (YMCK). The four color-separated images of the original document are created with toner on the drums and then transferred in registration onto the IBT Belt (IBT = Intermediate Belt Transfer) to reproduce a full color image. The completed toner image is transferred and fixed on the print medium, and then output as a print. The printing process of this printer is composed of the following basic steps: (1) Charging:....................... The drum surface is electrically charged. (2) Exposure:....................... The image is formed on the drum surface by the light from the LEDs (Light Emitting Diodes). (3) Development: ................The image is developed with toner. (4) Primary Transfer: ..........The four color separation images on the drums are transferred onto the IBT Belt. (5) Cleaning: ....................... The drums are electrically neutralized and the toner remaining on the drums and BCRs is removed. (6) Secondary Transfer: ...... The toner image on the IBT Belt is transferred onto the medium. (7) Neutralization:............... Electric charge of the paper is eliminated. (8) Cleaning: ....................... The toner remaining on the IBT Belt and 2nd BTR is removed. (9) Fusing:...........................The toner is fixed to the print medium by heat and pressure.

10.2.3 Feeding from Multipurpose feeder (MPF) When sheet feeding from the Multipurpose feeder (MPF) starts, the Feed Roll rotates, driven by the DRIVE ASSY MOT and controlled by the SOLENOID FEED MSI, to feed the sheet to the position where it is nipped between the Feed Roll and the Retard Roll. As the Feed Roll rotates, the CAM MSI L and CAM MSI R also rotate to lift the PLATE ASSY BOTTOM via the ARM MSI L and ARM MSI R to the position for sheet feeding.

Chapter 10 Machine Overview 10.2 Paper Path 10.2.3.1 Multiple Sheet Feed Prevention The sheets set in a tray or cassette is occasionally stuck together along the edges. The stuck sheets cause a multiple sheet feed or a jam. The sheets are fed by the Feed Roll to a position between the Feed Roll and the Retard Roll. Normally, when only one sheet passes through this position, both the Feed Roll and Retard Roll rotate to allow the sheet to pass. However, when two sheets, stuck together, attempt to pass through this position, only the Feed Roll rotates and the Retard Roll is locked, allowing only the upper sheet to pass by separating itself from the lower sheet that is stopped by the friction with the Retard Roll at rest. The Retard Roll is being pushed toward the Feed Roll by spring pressure, and controlled by the torque limiter (Clutch Assy Friction) with which it is coupled.

10.2.4 Feeding from Priority Sheet Inserter (PSI) When feeding from the Priority Sheet Inserter (PSI) starts, the Feed Roll rotates, driven by the DRIVE ASSY MOT and controlled by the SOLENOID FEED MSI, to feed the sheet to the position where it is nipped between the Feed Roll and the Retard Roll. Since the paper path from the MPF and the paper path from the PSI are the same, the sheets loaded in the PSI positioned nearer to the Feed Roll are given the higher priority in feeding, if both the MPF and the PSI are loaded.

10.2.5 Feeding in Registration Section The sheet fed out of the MPF or PSI is forwarded to the registration section, driven by the DRIVE ASSY MOT and controlled by the CLUTCH REGI. When the sheet reaches the registration section, its lead-edge position is adjusted (Refer to "10.2.5.1 Lead-edge Registration"), and then the sheet is forwarded to the toner transfer section (2nd BTR).

Chapter 10 Machine Overview 10.2 Paper Path 10.2.5.1 Lead-edge Registration When a sheet fed out of the MPF or PSI directly reaches the toner transfer section, the toner image may not be transferred at the correct position on the sheet due to misalignment of lead edges in the MPF or PSI. To avoid this problem, the lead edge position of the sheet needs to be corrected at the registration section before the sheet is forwarded to the toner transfer section. By thrusting the edge of the sheet fed out of the MPF or PSI against the Regi Roll (ROLL REGI / ROLL ASSY PINCH REGI) that is locked, the lead edge position of the sheet is registered.

10.2.6 Transfer/Fusing/Exit While the sheet that passed the registration section passes through the toner transfer position where it is nipped between the IBT Belt and the 2nd BTR that rotate driven by the DRIVE ASSY MOT, the toner image on the IBT Belt is transferred onto the sheet. As the sheet is forwarded to the exit section, the toner image is fused onto the sheet surface by the Heat Roll that rotates driven by the DRIVE ASSY MOT. At the exit section, the sheet is ejected by the Exit Roll that rotates in the exit direction driven by the DRIVE ASSY MOT.

Chapter 10 Machine Overview 10.4 Operation Modes

10.4 Operation Modes 10.4.1 Operation Modes The printer can be operated in the following four modes:  Printing Mode The printer is under printing.  Ready Mode The printer is ready for printing.  Low Power Mode The printer is under power saving. When the predetermined time elapses in the Ready Mode, the device goes into the Low Power Mode to reduce standby power consumption.  Sleep Mode The printer is under power saving. When the predetermined time elapses in the Low Power Mode, the device goes into the Sleep Mode to reduce standby power consumption.

Chapter 10 Machine Overview 10.5 Control

10.5 Control 10.5.1 Process Control The parameters related to image formation must be corrected to stabilize printing. The control of the entire printing process including the parameter correction control is called "process control". The process control is performed by the following two methods after every 30 cumulative prints upon termination of a print run or during a continuous run:  Potential Control  Toner Density Control To supplement these two controls, the following controls are provided:  High Area Coverage Mode  Admix Mode

10.5.1.1 Potential Control To stabilize the print image density, the drum charging voltage, the developing DC voltage, and the LED light amount of the LPH are adjusted according to the ever-changing developing capability of each color developer. The adjusted drum charging voltage, the developing DC voltage, and the LED light amount of the LPH are fed back to keep the print image density constant. The outline of control is as follows: 1)

The HUMIDITY SENSOR (temperature and humidity sensor) detects the temperature and humidity.

2)

The patches of respective colors (yellow, magenta, cyan, and black) for the potential control are generated and transferred onto the Belt.

3) 4)

The ADC Sensor (density sensor) detects the density of the patches on the Belt. The drum charging voltage, the developing DC voltage, and the LED light amount of the LPH are adjusted for each color according to the detected patch density.

10-13

Chapter 10 Machine Overview 10.5 Control 10.5.1.2 Toner Density Control The toner density must be kept constant to stabilize the print image quality. The control system for this purpose is called toner density control. 1)

ICDC (Image Count Dispense Control) The quantity of the toner to be consumed in the developing process is calculated in terms of toner dispensing time based on the quantity of the video signals that have been input to the LPH. The amount of the toner to be fed to the developer section is controlled by turning on the Toner Motor for the toner-dispensing time thus calculated.

2)

ADC (Auto Density Control) The patches of respective colors (yellow, magenta, cyan, and black) for the toner density control are generated under the specified potential condition, and then transferred onto the Belt. The ADC Sensor measures the densities of these patches and compares them with the reference value. If the toner density is lower than the reference value, the toner dispense quantity is increased at the next printing. If the toner density is higher than the reference value, the toner dispense quantity is reduced at the next printing. The toner dispense quantity is calculated in terms of the toner dispensing time on a color-by-color basis.

10.5.1.3 High Area Coverage Mode A continuous printing of a high area coverage data that exceeds the extra toner dispense capability causes the toner density in the developer to be lowered. The High Area Coverage Mode postpones the next page feed and dispenses the toner during this time if the toner dispense time has reached the specified value during a continuous printing.

10.5.1.4 Admix Mode This mode executes extra toner dispensation to prevent the toner density from being lowered whenever the value of the toner density control patch measured by the ADC Sensor falls far below the reference value. If the toner density level cannot be recovered even after this operation, it is determined that the toner has run out.

10.5.1.5 ADC Sensor Adjustment The ADC Sensor is a reflection type sensor that irradiates the light from its LED onto the target and detects the reflected light at its photoreceptor and outputs electric signals responsive to the amount of the detected light. To ensure an accurate patch density measurement, the surfaces of the ADC Sensor is cleaned to remove soil due to toner, etc., and the light quantity adjustment is made so that the reflected light quantity satisfies the predetermined value when the patch for potential control and toner density control are created.

10-14


10.5.2 Color Registration Control The printer uses a tandem system where the drums and developers are arranged respectively for each of yellow, magenta, cyan, and black colors. Since the four color-separated images are overlaid one another onto the print medium, a color shift may occur. The color registration control calculates how much the registration is shifted, and adjusts the LPH write timing. Color registration control is performed based on the change in the internal temperature of the device. The control is outlined below: 1)

With no toner on the Belt, the output value of the Sensor is measured to determine the threshold value.

2)

The patch for color registration control is generated on the Belt. For Type A, one patch is created on the AntiDrive (AD) side. For Type B, two patches are created, one for each on the AD side and on the Drive side.

3)

The density of the patch is measured by the Sensor.

4)

The shift correction amount is calculated from the threshold value determined in 1) and the patch density

measured in 3). 5)

The LPH write timing is changed according to the shift correction amount.

10-15


10.5.3 Fusing Unit Control 10.5.3.1 Fusing Unit temperature control To control the Fusing Unit temperature, the target temperature is set, and then the Heater Lamp is turned on/off so that the surface temperature of the Heat Roll satisfies the target value. The surface temperature of the Heat Roll is detected by the Temp. Sensor (STS: Soft Touch Sensor) in the middle of the Heat Roll and the Temp. Sensors at the end sections. When the temperature detected is higher than the target value, the Heater Lamp will be turned OFF. When the temperature detected is below the target value, the Heater Lamp will be turned ON. However, the STS may detect a temperature lower than the actual value when an error occurs during the temperature detection. To prevent, in such a case, the Heater Lamp from activating for too long a duration until it melts or burns the Fusing Unit Assy, the Heater Lamp is turned off unless Warm-up is completed within the specified time. The target temperature varies depending on the printer status such as Standby, Printing, or Process Control, and is calibrated according to the temperature difference between the middle section and the end section of the Heat Roll, the printing mode, and the input power supply voltage.

10.5.3.2 Cooling down As the printing continues, the temperature of the Heat Roll becomes nonuniform between the area that contacts the sheet and the area that does not. In such a case, the paper feeding is suspended for a certain duration to compensate for the temperature nonuniformity of the Heat Roll. This is called "Cooling Down". When the temperature of the Heat Roll end is high, cooling down is performed to lower the temperature to the target value.
