  • Page 22: Copy Process

    1.5 COPY PROCESS B070D872.WMF 1. EXPOSURE A xenon lamp exposes the original. Light reflected from the original passes to the CCD, where it is converted into an analog data signal. This data is converted to a digital signal, processed, and stored in the memory. At the time of printing, the data is retrieved and sent to the laser diode.
  • Page 23 3. LASER EXPOSURE The processed data from the scanned original is retrieved from the hard disk and transferred to the drum by four laser beams, which form an electrostatic latent image on the drum surface. The amount of charge remaining as a latent image on the drum depends on the laser beam intensity, which is controlled by the laser diode board (LDB).

    2. DETAILED SECTION DESCRIPTIONS 2.1 DOCUMENT FEEDER 2.1.1 PICK-UP ROLLER RELEASE B070D916.WMF When the original set sensor is off (no original on the original tray), the pick-up roller stays in the up position. When the original set sensor turns on (or when the trailing edge of a page passes the entrance sensor while pages remain on the original tray), the pick-up motor [A] turns on.

  • Page 27: Bottom Plate Lift

    2.1.2 BOTTOM PLATE LIFT B070D917.WMF When an original is placed on the original tray, the original set sensor [A] turns on, the pick-up roller [B] drops on to the original, and the bottom plate position sensor [C] turns off. Then the bottom plate motor [D] turns on and lifts the bottom plate [E] by raising the lift lever [F] until the bottom plate position sensor turns on.

  • Page 28: Pick-Up And Separation

    2.1.3 PICK-UP AND SEPARATION B070D918.WMF B070D919.WMF The original separation system is a Feed and Reverse Roller (FRR) system. The pick- up roller [A], feed belt [B], and separation roller [C] are driven by the feed-in motor [D]. To drive this mechanism, the feed-in motor [D] and feed-in clutch [E] turn on. Handling Paper>...

  • Page 29: Original Feed

    2.1.4 ORIGINAL FEED B070D920.WMF When the leading edge of the original turns the entrance sensor [A] on, the feed-in clutch [B] turns off and the drive for the feed belt is released. The original is fed by the transport rollers [C]. At the same time, the pick-up motor starts again and the pick-up roller [D] is lifted up.

  • Page 30: Original Size Detection

    2.1.5 ORIGINAL SIZE DETECTION B070D921.WMF The ADF detects the original size by combining the readings of original length sensor [A], and original width sensors-1 [B], -2 [C], and -3 [D]. Original Length The original length sensor and the disk [E] (connected to the transport roller) generate a pulse signal.

  • Page 31: Original Transport

    2.1.6 ORIGINAL TRANSPORT B070D923.WMF The transport belt [A] is driven by the transport belt motor [B]. The transport belt motor starts when the copier sends an original feed-in signal. The pressure rollers inside the transport belt maintain the correct pressure between belt and original.

  • Page 32: Original Skew Correction

    2.1.7 ORIGINAL SKEW CORRECTION The transport belt motor remains energized to carry the original to the right about 7 mm past the left scale [A]. Then the motor stops and reverses to feed the original 12 mm to the left against the left scale to correct skew. This forces the original to hit the left scale, which aligns the trailing edge to minimize original skew on the exposure glass.

  • Page 33: Original Inversion And Feed-Out

    2.1.8 ORIGINAL INVERSION AND FEED-OUT General Operation B070D926.WMF When the scanner reaches the return position, the copier CPU sends the feed-out signal to the ADF. When the ADF receives the feed-out signal, the transport belt motor and feed-out motor [A] turn on. The original is then fed out to the exit tray or fed back to the exposure glass after reversing in the inverter section.

  • Page 34: Original Inversion

    Original Inversion B070D927.WMF When the ADF receives the original invert signal from the copier, the transport belt motor, feed-out motor, exit gate solenoid [A], and inverter gate solenoid [B] turn on and the original is fed back to the exposure glass through the inverter roller [C], exit gate [D], inverter guide roller [E], inverter gate [F], and inverter roller.

  • Page 35: Original Exit (Single-Sided Original Mode)

    Original Exit (Single-Sided Original Mode) B070D928.WMF The exit gate solenoid [A] remains off, the exit gate [B] remains closed, and the original is fed out to the right exit tray. The speed of the motor is reduced about 30 mm from the trailing edge of the original to ensure the originals stack neatly on the exit tray.

  • Page 36: Original Exit (Double-Sided Original Mode)

    Original Exit (Double-Sided Original Mode) B070D929.WMF The exit gate solenoid [A] turns on and the exit gate [B] opens. The inverter gate solenoid [C] remains off, and the original is fed out to the upper tray. The transport belt motor turns off when the trailing edge of the original passes the exit sensor [D].

This multi-beam exposure mechanism has the following advantages: • Reduces the number of rotations required of the polygon mirror motor. •...

  • Page 59: Polygon Mirror Motor

    2.4.5 POLYGON MIRROR MOTOR The polygon mirror reflects the laser beam onto the OPC drum to expose the image line by line in the main scan direction. The polygon mirror motor rotates at a constant speed, even while the copier is in standby mode, but shuts off when the copier enters the energy conservation mode.
  • Page 60 2.4.6 1200-DPI RESOLUTION Sub Scan 0 LDA 1-0 42.3 µm (600 dpi) 1 LDA 2-0 2 LDA 1-1 3 LDA 2-1 The original is scanned at 600 dpi, then the 600 dpi output is boosted to 1200 dpi 1-bit data during image processing in the IPU. This machine can produce an image at 1200 dpi by writing each dot twice, possibly with two different values, depending on the results of image processing.

  • Page 61: Optical Path

    2.4.7 OPTICAL PATH B070D101.WMF The output path from the laser diode to the drum is shown above. The LD unit [A] outputs eight laser beams to the polygonal mirror [B] (six mirror surfaces) through the cylindrical lens [C] and the 1st mirror [D]. Each surface of the polygon mirror reflects eight full main scan lines.

  • Page 62: Process Control

    2.5 DRUM UNIT 2.5.1 PROCESS CONTROL Drum potential gradually changes for the following reasons: • Dirty optics, exposure glass • Dirty charge corona casing, grid plate • Deterioration of drum sensitivity What Happens at Power On Here is a description of what happens while the fusing temperature is below 100°C immediately after the main power switch is switched on (process control must also be enabled with SP3901 001, or this will not happen).
  • Page 63 2.5.2 DRUM UNIT COMPONENTS The drum unit consists of the components shown in the above illustration. An organic photoconductor drum (diameter: 100 mm) is used for this model. 1. OPC Drum 2. Drum Potential Sensor 3. Pick-off Pawl 4. Image Density Sensor 5.

  • Page 64: Drum Drive

    2.5.3 DRUM DRIVE B070D202.WMF The drive from the drum motor [A] is transmitted to the drum and the cleaning unit through timing belts, gears, the drum drive shaft [B], and the cleaning unit coupling [C]. The drum motor has a drive controller, which outputs a motor lock signal when the rotation speed is out of the specified range.

  • Page 65: Drum Charge

    2.5.4 DRUM CHARGE Overview B070D203.WMF This copier uses a double corona wire Scorotron system to charge the drum. Because of the high speed of this copier, two corona wires are needed to give a sufficient, uniform negative charge to the drum surface. The stainless steel grid plate makes the corona charge uniform and controls the amount of negative charge on the drum surface by applying a negative voltage to the grid.
  • Page 66 Charge Corona Wire Cleaning Air flowing around the charge corona wire may deposit toner particles on the corona wires. These particles may interfere with charging and cause low density bands on copies. The wire cleaner pads [A] automatically clean the wires to prevent such a problem. The wire cleaner is driven by a dc motor [B].

  • Page 67: Drum Cleaning

    2.5.5 DRUM CLEANING Overview B070D866.WMF This copier uses a counter blade system to clean the drum. In a counter blade system, the drum cleaning blade [A] is angled against drum rotation. The counter blade system has the following advantages: • Less wearing of the cleaning blade edge •...

  • Page 68: Cleaning Unit Drive

    2.5.6 CLEANING UNIT DRIVE B070D206.WMF Drive from the drum motor is transmitted to the cleaning unit drive gear via the timing belt [A] and the cleaning unit coupling [B]. This coupling drives the cleaning brush [C] directly. The cleaning brush then transmits the drive to the gear at the front, which drives the toner collection coil gear [D].

  • Page 69: Cleaning Blade Pressure And Side-To-Side Movement

    Cleaning Blade Pressure and Side-to-Side Movement The spring [A] always pushes the cleaning blade against the drum. The cleaning blade pressure can be manually released by pushing up the release lever [B]. To prevent cleaning blade deformation during transportation, the release lever must be locked in the pressure release (upper) position.

  • Page 70: Air Flow Around The Drum

    2.5.7 OTHERS Air Flow Around the Drum B070D208.WMF The drum cooling fan [A] draws cool air through the filter [B] and sends it to the center of the drum [C], then over the charge corona unit [D]. Holes in the flanges on both ends of the drum allow air to pass through the drum to cool it.

  • Page 71: Drum Pick-Off Pawls

    Drum Pick-off Pawls B070D559.WMF If the paper does not separate from the drum after image transfer, the drum pick-off pawls strip the paper from the drum. Pressure from small springs [A] press the pick-off pawls [B] against the surface of the drum.

Doctor Blade This copier uses a double roller development system and a dual component development process with toner particles 6.8 µm and developer particles 50 µm.

  • Page 74: Development Mechanism

    2.6.2 DEVELOPMENT MECHANISM B070D303.WMF Toner and developer are mixed in the toner agitator by the cross-mixing roller [A]. The paddle roller [B] picks up the developer and sends it to the upper development roller [C]. Internal permanent magnets in the development rollers attract the developer to the development roller sleeve.
  • Page 75 2.6.3 DRIVE B070D304.WMF The gears in the development unit are driven by the development drive gear [A] when the development motor [B] (a dc servomotor) turns. The gears in the toner hopper are driven by the toner supply roller drive gear [C] when the toner supply roller clutch [D] activates.
  • Page 76 2.6.4 CROSSMIXING B070D303.WMF This copier uses a standard cross-mixing mechanism to keep the toner and developer evenly mixed. It also helps agitate the developer to prevent developer clumps from forming and helps create the triboelectric charge. The developer on the turning development rollers [A] is split into two parts by the doctor blade [B].

  • Page 77: Development Bias

    2.6.5 DEVELOPMENT BIAS B070D305.WMF The CBG (Charge Bias Grid) power pack [A] applies the negative development bias (- 550V) to both the lower sleeve roller and upper sleeve roller through the receptacles [B] and the sleeve roller shafts [C]. The development bias prevents toner from being attracted to the non-image areas on the drum where there is residual voltage.

  • Page 78: Toner Supply And Recycling

    2.7 TONER SUPPLY AND RECYCLING 2.7.1 OVERVIEW B070D902.WMF Toner is supplied from a toner bank [A] on the left side of the machine and separated from the development unit. The toner bank holds two bottles, but only one bottle operates at a time. A toner bottle motor turns the bottle [B], causing toner to leave the bottle and drop into the toner entrance tank [C].

  • Page 79: Toner Bank

    2.7.2 TONER BANK Toner Bottle Switching Mechanism B070D901.WMF When the upper toner bottle [A] is supplying toner, the upper bottle cap motor [B] pulls out the toner bottle cap. The upper bottle cap sensor [C] detects the actuator [D] of the toner bottle opening rod, then the motor shuts off to close the cap again.
  • Page 80 Toner Near-end, Toner End, Bottle Replacement B070D911.WMF B070D909.WMF Each toner bottle [A] has an independent toner bottle motor [B]. An empty toner bottle can be replaced during printing. The toner near-end sensor detects toner as it falls from the toner bottle into the toner entrance tank [C].
  • Page 81 Meanwhile, the machine indicates that the first bottle is empty. When the user takes out the old bottle, and puts in a new one, this is detected by the toner bottle sensor. ( ”Toner Bottle Sensors”,2-57) However, this bottle is not tested until the second bottle is empty.

  • Page 82: Toner Bottle Sensors

    Toner Bottle Sensors B070D913.WMF B070D912.WMF B070D914.WMF When placing a toner bottle in the toner bank, the toner bottle pushes the lock arm [A] downwards. Then the lock arm catches the toner bottle and also pushes down lever [B]. This causes toner bottle sensor [C] to detect that a bottle has been installed (the actuator leaves the toner bottle sensor while the bottle is being inserted in the holder).

  • Page 83: Supplying Toner To The Development Unit

    2.7.3 SUPPLYING TONER TO THE DEVELOPMENT UNIT B070D902.WMF B070D906.WMF The toner bottle motor turns the toner bottle [A], causing toner to leave the bottle and drop into the toner entrance tank [B]. NOTE: Recycled toner in the tube from the drum cleaning unit also enters the toner entrance tank, and is mixed with fresh toner from the toner bottle.
  • Page 84 If the toner hopper sensor (in the toner hopper - Toner Hopper) detects an insufficient amount of toner in the hopper, the toner bank mechanism is started up. If there is sufficient toner in the toner entrance tank (detected by the toner near end sensor in the toner bank), the toner supply coil clutch turns on for 2 seconds.

  • Page 85: Toner Hopper

    2.7.4 TONER HOPPER Toner Supply A294D306.WMF When the toner supply roller clutch [A] (inside the development motor unit [B]) turns on, the agitator [C] mixes the toner transported by the air tube [G] from the toner bank (the toner from the toner bank is new toner mixed with recycled toner). Then it moves the toner from front to rear and sends it to the toner supply roller.

  • Page 86: Toner Hopper Empty Detection

    Toner Hopper Empty Detection A294D307.WMF The toner hopper sensor [A] detects whether there is enough toner in the toner hopper. The toner hopper sensor checks for toner once when the toner supply roller clutch turns on. When there is only a small amount of toner inside the toner hopper and pressure on the toner hopper sensor becomes low, the toner hopper sensor outputs a pulse signal (once per copy).

  • Page 87: Toner Recycling And Waste Toner Collection

    2.7.5 TONER RECYCLING AND WASTE TONER COLLECTION Overview B070D903.WMF To recycle used toner for re-use, the toner recycling coil in the tube [A] transports the toner collected by the drum cleaning to the toner entrance tank for recycling.

  • Page 186: Paper Pre-Stacking

    7.5.2 PAPER PRE-STACKING B478D000.WMF This mechanism improves productivity in staple mode. It is only used when copying on A4, LT, or B5 (all LEF). During stapling, the copier has to wait. This mechanism reduces the wait by holding the first two sheets of a job while the previous job is still being stapled. It only works during the second and subsequent sets of a multi-set copy job.

  • Page 187: Jogger Unit Paper Positioning

    7.5.3 JOGGER UNIT PAPER POSITIONING In the staple mode, as every sheet of paper arrives in the jogger unit, it is vertically and horizontally aligned, then the staple edge is pressed flat to ensure the edge of the stack is aligned correctly for stapling. Vertical Paper Alignment: About 60 ms after the trailing edge of the copy passes the staple tray entrance sensor [A], the positioning roller motor [B] is energized to push the positioning roller [C] into contact with the paper.

  • Page 188: Stapler Unit Movement

    7.5.4 STAPLER UNIT MOVEMENT Side-to-Side The stapler motor [A] moves the stapler [B] from side to side. After the start key is pressed, the stapler moves from its home position to the stapling position. If two-staple-position mode is selected, for the first stack the stapler moves to the rear stapling position first, staples, moves to the front position, staples and waits at the front.
  • Page 189 B478D514.WMF B478D515.WMF Rotation (1) In the oblique staple position mode, the stapler rotation motor [A] rotates the stapler units [B] 45° to counterclockwise after it moves to the stapling position. Rotation (2) When the staple end condition arises, the stapler motor moves the stapler to the front and the stapler rotation motor rotates the stapler unit to clockwise to remove the staple cartridge [C].
  • Page 190 7.5.5 STAPLER B478D516.WMF B478D521.WMF B478D522.WMF When the aligned copies are brought to the stapling position by the positioning roller and jogger fences, the staple hammer motor [A] starts stapling. During stapling, the stapler trims off the excess length [B] of the staples by lowering the cutter [C].
  • Page 191 B478D518.WMF B478D517.WMF The stapler has a staple end sensor [A], cartridge set sensor [B] and staple hammer HP sensor [C]. When a staple end or no cartridge condition is detected, a message is displayed advising the operator to install a staple cartridge. If this condition is detected during a copy job, the indication will appear, and the copy job will stop.
  • Page 192 7.5.6 FEED-OUT B478D519.WMF B478D512.WMF After the copies have been stapled, the stack feed-out motor [A] starts. The pawl [B] on the stack feed-out belt [C] transports the set of stapled copies up and feeds it to the shift tray exit roller [D]. When stapling starts, the exit guide motor [E] opens the upper exit guide [F], which includes the upper shift tray exit roller [G], in order to feed out the leading edge of the copy set smoothly.

  • Page 193: Paper Exit Stacking

    7.5.7 PAPER EXIT STACKING The stacking roller assembly [A] is fastened to a plate [B] on a shaft by a spring [C]. The cam [D], in contact with the bottom of the plate, is connected to the stacking roller drag motor [E] via a timing belt. The stacking roller drag motor and timing belt rotate the cam against the bottom of the plate to move the rollers forward and back with each sheet ejected onto the shift tray.

  • Page 194: Shift Tray

    7.5.8 SHIFT TRAY Overview B478D010.WMF The shift tray lift motor [A] controls the vertical position of the shift tray [B] through gears and timing belts [C]. Stand-by Mode After the main switch is turned on, or when the stack is removed from the tray, the end of the feeler on the tray falls and its actuator [D] rotates up into staple mode HP sensor 2 [E] (S7) and switches it on.

  • Page 195: Shift Tray Up/Down Movement

    7.5.9 SHIFT TRAY UP/DOWN MOVEMENT B478D010.WMF Sort/Stack Mode (Shift Mode) The shift tray moves to home position, which is when the actuator [F] has just exited the shift mode home position sensor [G] (S12). During feed-out, the tray is lowered automatically at prescribed intervals; sensor [D] (S7) is ignored. When the stack is removed from the tray, the end of the feeler [E] between the arms of the stacking roller falls, and its actuator [F] enters sensor [G] (S12) and switches it on.

  • Page 196: Shift Tray Lower Limit Detection

    7.5.10 SHIFT TRAY LOWER LIMIT DETECTION B478D010.WMF This machine has two shift tray lower limit sensors: shift lower limit sensor [A] (S9) for large paper (B4 and larger) and shift lower limit sensor [B] (S11) for small paper (smaller than B4). NOTE: Sensor [C] (S10) is not used.

  • Page 197: Shift Tray Side-To-Side Movement

    7.5.11 SHIFT TRAY SIDE-TO-SIDE MOVEMENT B478D520.WMF In sort/stack mode, the shift tray [A] moves from side to side to separate the sets of copies. The horizontal position of the shift tray is controlled by the shift motor [B] and shift gear disk [C].

  • Page 198: Jam Conditions

    7.6 JAM CONDITIONS 1. The entrance sensor does not turn on when the copier has fed paper 426 mm after the copier exit sensor turned off. 2. The entrance sensor does not turn off when the upper transport motor has fed paper 1.5 times the paper’s length after it turned on.

  • Page 199: Punch Unit B531 (Option)

    7.7 PUNCH UNIT B531 (OPTION) 7.7.1 PUNCH UNIT DRIVE B531D102.WMF The punch unit makes 2 or 3 holes at the trailing edge of the paper. The number of holes depends on a selection made on the operation panel. The cam [A] has 2 punches on one side and 3 punches on the other, and is turned by the punch motor [B].
  • Page 200 7.7.2 PUNCH WASTE COLLECTION B531D103.WMF Punch waste is collected in the punch waste hopper [A] positioned under the punch unit. When the level of the punch waste in the hopper rises as far as the hole [B] in the hopper, the punch waste sensor [C] turns on, stops the job, and triggers a message on the operation to indicate that the hopper is full and must be removed and emptied.
