    Bizhub 283 C1004

    User originally called with code c-1004. When I arrived the machine displayed turn main power off/on with code L-8. I deleted all trouble codes. Did a trouble code reset. Now the machine just displays turn power off/on. In addition to above I have tried:
    a firmware rewrite
    unplugging finisher and powering off and on.

    I put a Bizhub 223 in its place for now. That one won't feed from tray 3 . But trays 1,2, and 4 work fine. Paper gets about half way out of the tray. I replaced the entire tray 3 feed unit and motors from working 283 with same result. I ordered the clutch's, rollers, and torque limiter anyway to try that. Should be here Monday.

    Thanks in advance!

    Did you unplug the bridge unit from the machine before powering up? The finisher connects to the bridge, then the bridge to the MFPB.

    So if it won't power up with bridge and finisher disconnected, it could be the MFPB. If it does power up without the finisher it could be the JSCB (bridge controller), or FSCB (finisher controller).

    As experience goes, I've seen one bad bridge controller, and no bad finisher controllers.

    Can you get into service mode to do a System Error Clear?
    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.

    Thank you very much for taking the time to reply.

    Not sure what a bridge is. The finisher is internal. I pulled the gray plug from the back of the 283. The manual says:

    When the FSCB is receiving data, a communication error is detected.

    Later it has a grid on page K-138.

    So I don't know if I should be looking at the FCSB or the JSCB. Maybe because I don't know what ICP is

    Initially i was able to get into service mode and I did clear all the codes.

    Ah! I don't think you mentioned the part about an internal finisher. You don't have a bridge.

    An internal finisher does not use a bridge, so you do not have a JSCB. An ICP is a microscopic fuse soldered onto a circuit board. Perhaps you have better soldering skills than I do, but I haven't had much luck de-soldering then re-soldering a fuse measuring 1.5mm x 3.0mm. Here's a picture of a failed ICP3 I came across recently (it's at the phone's maximum enlargement):

    Thanks again for the reply.

    I did not mention it originally. I realized after your reply. I thought a bridge might be for an external finisher. So that reminded me that I should probably mention it

    Since there is no JSCB I can rule out the grid and worrying if the ICP is firing. But at least I know what one is now

    Since there is no JSCB, it can only be the FSCB? Do I need to remove the finisher for that?

    Re: Bizhub 283 C1004

    So you unplugged the finisher and the MFP still does not power up?

    Make the following live checks @ the FS-529 controller board:
    ICP R1 (24VDC both ends to ground)
    ICP CP1 (24VDC both ends to ground)
    CN83L pin1 to CN83L-4 (24VDC)

    Check the MFPB:
    Re-seat CN22 at MFPB
    Re-seat CN93 at back cover
    Re-seat CN83A at FS-529

    Check DC Power Supply:
    CN6 pin 2 to CN6 pin5 (24VDC)

    I can help to interpret the results. =^..^=

    I did unplug the gray plug, I assumed was the finisher.

    This will be the first time I have used a meter. First I'll have to buy a meter. So I'll be measuring DV volts?

    Yes, correct. =^..^=

    I am afraid I didn't see any of these in the picture or the manual grid.

    Same with these, except CN22. I did see that one.

    Re: Bizhub 283 C1004

    I think I am getting smarter. lol This is the CN83L right? How do I know what pin is 1,2,3, and 4?

    I can check CN93 tomorrow. CN83A connects to CN93.

    I don't see anything that says ICP on the board. I see IC followed by a number, but haven't found ICR1 or just R1 or CP1. Found everything but of course. I took pics so I will be scouring those tonight. I am looking at the FSCB for those.
