• Replace the development unit before adding new developer.
  • When the toner is ended, you should replace the toner before adding new developer, because initialization for the TD sensor and density adjustment process control will not be executed if there is no toner.
  • The drawer unit, vertical transport door, and bypass tray door should be opened when adding new developer, otherwise SC682-07 is logged.

  1. Turn OFF the power.
  2. Remove the toner supply unit. (Toner Supply Unit)
  3. Remove the faceplate. (Faceplate)
  4. Remove the PCDU. (PCDU)
  5. Replace the development unit. (Development Unit)
  6. Attach the PCDU.
  7. Attach the faceplate.
  8. Turn ON the machine.

  9. Attach the funnel [A] to the supply port [B] of the development unit.

    • Protrusion [A] at the bottom of the funnel is a stopper. Make sure that the protrusion is inserted securely into the slot at the back side of the supply port [B] of the development unit.

  10. Shake the developer pack [A] 5 or 6 times.
  11. Enter SP mode and execute SP3-024-00x (Developer Fill). See the table below.

  12. Fill the developer [A] while tapping the funnel. It should finish within 60 seconds. Make sure that the error message "Failed" does not appear.

    • Execution time for filling developer is 60 seconds as the default. The time interval for execution can be adjusted. If more time is needed to empty the developer pack, increase the time interval with SP3-024-11 (Developer Fill: Exe Drive Time Upper Limit).
    • If the filling is not completed in time, see the result code table below.
    • If the error message "Failed" is displayed after executing SP3-024-XXX (Developer Fill :Exe Execute), check the execution result code with SP3-025-001 (Dev Fill OK?). Then perform the recovery procedure shown in "Result code table for filling developer" below. After performing the recovery procedure, make sure that "1" is displayed in SP3-025-001 (Dev Fill OK?).

  13. After the filling completion message is displayed on the touch panel display, enter SP3-025-001 (Dev Fill OK? From Left:YMCK) to confirm that developer installation succeeded.
    You will see a 4-digit number: 1111. Reading from left-to-right, each number is a result code for the Y, M, C, K developer execution with SP3-024-00. Refer to the result code table below.

    Even though the results display of SP3025 shows success, developer may remain in the funnel. In this case, implement the following output checks in order to fill the remaining developer.

    • Set SP5-805-114 (Output Check Used Toner Bottle Motor) to ON “1”.
    • Set SP5-805-115 (Output Check Toner Discharge Motor) to ON “1”.
    • Set SP5-805-112, -113, -114 or 115 (Output Check Dev Motor) to ON “1”.
    • After the completion of filling, set the output checks to OFF.

    2

    No developer exited

    Before execution, TD sensor output was above 1.0V (developer present).

    The developer is filled with about 150 to 200g when the time expires

    Deal with this in the following order.

    • Turn OFF the main power.
    • Carefully remove the funnel for which the developer is remaining.
    • Remove the PCDU and attach the cap to the supply port.
    • Tilt the PCDU about 45 degrees towards the toner supply unit, closer to the developer supply port side in the vicinity of the TD sensor.
    • Attach the PCDU.
    • Attach the funnel that has the developer remaining.
    • Turn ON the main power and run the developer filling with SP3-024.
    • Make sure that "1" is the result with SP3-025.

    2

    No developer exited

    Before execution, TD sensor output was above 1.0V (developer present).

    When removing the developer during EM, if developer remains in the development unit

    Deal with this in the following order.

    • Turn OFF the main power.
    • Remove the PCDU and remove the developer in the PCDU.
    • Attach the PCDU and the funnel
    • Enter SP mode and execute SP3-024-00x (Developer Fill).
    • Fill the developer

    3

    No developer entered

    After execution, TD sensor output was below 1.0V (no developer present).

    Remaining developer is less than 150g when the time expires

    • Enter SP mode and execute SP3-024-00x (Developer Fill).
    4Used toner bottle not setThe used toner bottle was not detected.No waste toner bottle in the machine
    • Put the waste toner bottle in the machine.
    • Enter SP mode and execute SP3-024-00x (Developer Fill).

    5

    Used toner bottle full

    The used toner bottle was detected full.

    If the waste toner bottle is full when filling the developer

    • Replace the waste toner bottle.
    • Enter SP mode and execute SP3-024-00x (Developer Fill).

    7

    Development motor lock

    The development motor was not operating.

    If the development motor is locked (SC325 to SC328) when filling the developer

    • Clear the SC325 to SC328.
    • Enter SP mode and execute SP3-024-00x (Developer Fill).

    8

    Used toner transport lock

    One or both motors locked: Used Toner Transport Motor, Used Toner Bottle Motor.

    One or both motors is locked: Used Toner Transport Motor, Used Toner Bottle Motor. (SC 486/SC488)

    • Clear the SC 486/SC488.
    • Enter SP mode and execute SP3-024-00x (Developer Fill).

    9

    Forced abort

    Bypass tray cover opened, waste toner front cover opened, the machine was powered off, or some other event interrupted execution.

    When the situation on the left happened when filling the developer

    Deal with this in the following order.

    • Enter SP mode and execute SP3-024-00x (Developer Fill).
    • If the result code is not "1", replace the developer.
  14. Remove the funnel and turn off the power.

  15. Attach the toner supply unit and turn on the power.

    • After turning on the main power switch, initialization for the TD sensor and process control automatically starts.

  16. Check the initialization results for the TD sensor (SP3-031-00x (Init TD Sensor: Exe Execute)). If the initialization is successful, the result shows “1111”.

    • If "1111" is not displayed, solve using the steps that are described in the table above.

  17. Check the initialization results for process control (SP3-012-001 (ProCon OK? History:Latest)). If the initialization is successful, the result shows “11111111”.
