    C1070 C-2824

    Error
    C-2821 (Y), C-2822 (M), C-2823 (C) or C-2824 (K)

    Root Cause
    Charging potential Vh terminated abnormally.

    Workaround/Fix
    To troubleshoot:
    1. Check the connection of the process carriage drawer connectors.
    2. Access I/O check mode 51-xx. It should be ON. If not, replace the subject part.
    • xx=00 (Eraser lamp/Y - EL Y)
    • xx=01 (Eraser lamp/M - EL M)
    • xx=02 (Eraser lamp/C - EL C)
    • xx=03 (Eraser lamp/K - EL K)

    3. Check the connection of CN160/CN161/CN162 (Printer Control board) and wiring for the connectors. If any problem is found, correct it.
    4. Check if ICP16 on the Printer Control board (p/n A1RF H050 0D) is OPEN. If so, replace the problem board.
    5. If the cause could not be specified by the above steps, replace the parts in the following order.
    • Printer control board
    • Drum potential sensor/Y/M/C/K (p/n A1RF R747 00)
    • Eraser lamp/Y/M/C/K (p/n 65AA 8307 0)
    • Wiring (p/n A1RF N123 03 - Main Body Wiring /3, p/n A1RF N147 00 - Transfer Wiring /1 and p/n A1RF N151 00 - Toner Detection harness /1)

      I must add that after replacing the black developing unit it did run for a half day.

              There's an adjustment that you must do any time you clean or touch the IDC sensors. Auto-something something ... I'll check. =^..^=
              If you'd like a serious answer to your request:
              1) demonstrate that you've read the manual
              2) demonstrate that you made some attempt to fix it.
              3) if you're going to ask about jams include the jam code.
              4) if you're going to ask about an error code include the error code.
              5) You are the person onsite. Only you can make observations.

                  Sorry so long:
                  It's Machine Adjustment > Printer Adjustment > Color Registration Auto Adjustment (run up to [3] times).

                      Re: C1070 C-2824

                      Yea I run the Auto gamma and that Color Registration adjustment you speak of everytime I touch anything.

                      I have swapped entire carriages, K Drum, K Developer unit, charge, prcb, color reg assy. ]

                      The machine we move it to still does not code out. This one still does. Laser or Wiring (backordered) is my plan. Really wooping me.....

                          This machine is in my office. We have a printshop out front. We have 2 of them so I can swap parts if you have any suggestions.

                          Thanks

                              My main suggestion is: don't touch the black laser if you don't have to.

                              All the color registration and image adjustments are based on the position of the black laser. Move it, and you'll spend a lot of time doing adjustments (even if you just take it in and out).

                              It could be a laser. =^..^=
