  • Page 354: Toner Supply Control

    Process Control The quantity of toner on the transfer belt (M/A, mass per unit area, mg/cm ) is calculated for each of the 10 gradations of the sensor pattern. To do this, the machine uses the ID sensor output value from each gradation of the pattern.

  • Page 359: Paper Feed Drive

    6. Detailed Function Descriptions Paper Feed Drive The paper feed and fusing motor controls the paper feed roller [A], by-pass feed roller [B] and registration roller [C] with clutches and gears. The paper feed roller and by-pass feed roller feed a sheet of paper to the registration roller.

  • Page 360: Paper Tray

    Paper Feed Paper Tray Paper Lift When the tray [A] is put in the machine, the tray arms [B] move along the guide slopes [C] of the main frame. This makes the springs [D] lift the bottom plate. The bottom plate [E] pushes the paper against the paper feed roller and keeps the top sheet of paper at the correct height.
  • Page 361 6. Detailed Function Descriptions Paper Size Detection The paper size sensor is at the rear of the tray. This sensor has four switches. The outputs from the switches detect the paper size, as shown in the table. The actuators are on the side plate [A]. The side plate is moved by the end plate [B] through a cam [C].
  • Page 362 Paper Feed Paper Near End/End Detection There are four sensors in tray 1: the two near end sensors [B] [E], the end sensor [C] and the paper width sensor [A]. Near-end detection Two near end sensors detect the amount of paper in the tray. When the quantity of paper decreases, the bottom-plate-pressure lever moves up and the actuator [F] (on the pressure-lever drive shaft) turns.

  • Page 366 Paper Feed Interleaving Step 1: This duplex unit uses the interleaving mechanism. This decreases the total time of duplex printing. The machine prints on side [1]. Then, the first sheet of paper is fed out of the exit, but not fully. Then the exit roller changes direction and the paper goes to the duplex feed path.
  • Page 367 6. Detailed Function Descriptions Step 2: The machine prints side [3] on the second sheet of paper. The second sheet of paper is fed to the paper exit, and into the duplex feed path. At the same time, the first sheet of paper is fed between the transfer belt and the transfer roller, and side [2] is printed.

The LD safety switch system stops the laser beam when the cover is open.

    Laser Exposure Automatic Line Position Adjustment Overview YY, KK, CC, MM: Spaces between two lines of the same color KY, KC, KM: Spaces between a black line and a color line During automatic line position adjustment, the line patterns above are made eight times on the transfer belt. The spaces between the lines (YY, KK, CC, MM, KY, KC, KM) are measured by the left, center, and right ID sensors.
  • Page 373 6. Detailed Function Descriptions Summary of Each Adjustment Sub scan line position for YCM The adjustment of the sub-scan line position for YCM uses the line position for K (color registration). The machine measures the gaps between the lines of each color in the pattern on the transfer belt. If the gaps for a color are not correct, the machine moves the image of the color up or down the sub scan axis.

  • Page 380: Drum Charge And Quenching

    Photoconductor Unit Drum Charge and Quenching This machine uses a charge roller [A]. The charge roller gives the drum surface a negative charge. The high voltage supply board, which is at the rear of the machine, applies a dc and ac voltage (at a constant current) to the roller.

  • Page 381: Drum Cleaning

    6. Detailed Function Descriptions Drum Cleaning The cleaning brush [A] makes flat the waste toner on the drum. The lubricant bar [B] lubricates the brush. The cleaning blade [C] then removes the waste toner. The toner collection coil [D] moves the toner to the waste toner collection duct.

  • Page 382: Waste Toner Collection

    Photoconductor Unit Waste Toner Collection The waste toner from the collection coils in the four PCUs falls into the waste-toner collection bottle from the four openings [I][J][K][M] at the rear of the PCUs. The toner collection coils [B][C][D][G] move this waste toner to the waste toner bottle [L].

  • Page 383: Waste Toner Bottle Full Detection And Set Detection

    6. Detailed Function Descriptions The pin [E] at the waste toner entrance pushes the shutter spring [F] in the rear of the PCU. Because of this, waste toner can fall into the waste toner bottle. If the left cover is open, the waste toner does not come out from the rear of the PCUs.

  • Page 384: Pcu Detection (Development Unit Detection)

    Photoconductor Unit PCU Detection (Development Unit Detection) Unit Set Detection Pins Each PCU has a connector [A]. The machine uses this to detect if the PCUs and development units are in the machine. Each PCU is detected through this connector when the drum positioning plate is closed. New Unit Detection Each PCU also has a circular hook [B].
  • Page 385 6. Detailed Function Descriptions If two or more PCUs are not detected, the second message shows those colors, for example “Yellow/ Cyan” and “Yellow/Magenta Black.

    6. Detailed Function Descriptions The machine automatically controls the dc bias, if automatic process control is enabled. However, if process control is turned off, (that is, if SP3-501-001 is set to 1), the dc bias is the value stored in SP2212-001 to –009 (do not adjust in the field unless told to do this).

The transfer belt rotation sensor [B] detects when the transfer belt entrance roller turns. It also detects the belt speed.

  • Page 392: Drive And Transfer Belt Roller Voltage

    Image Transfer Drive and Transfer Belt Roller Voltage The transfer belt motor [A] controls the transfer belt drive roller [B]. The belt tension roller [C] adds tension to the transfer belt to help to turn this belt. The speed of transfer belt drive is set by the process line speed. The belt transfer rollers [D] are charged from the terminal plates to move the toner from the PCUs to the transfer belt.
  • Page 393 6. Detailed Function Descriptions The transfer belt contact motor [A] turns the CMY contact cam shaft [B] when the machine starts to make a color print. The CMY contact cam lifts the belt transfer roller unit for CMY [C] to the transfer belt. Because of this mechanism, the life of the transfer belt is longer (it is not necessary for the transfer belt to touch the color PCUs when the machine makes a black and white print).
