    C1100 error C2236 and C2237.

    Been ask to go look at a machine after its been down for a week or so.
    The original call the tech was called out for was yellow scattering.

    He tells me the machine was over-toned on yellow and yellow toner everywhere.
    Dev and drums were 30% over life at the time.

    After he removing cleaning out and installing the drum cradle back, it was just going now warming up forever.
    My guess would be that it was not stabilizing ok.
    At this he took the fuser to another machine to test and tested ok.

    Next he changed the PRCB that poped up with a firmware mismatch that got fixed by updating it.
    After that continues giving C2237 and C2236 codes. (IDC shutter failure)
    Installing the original PRCB back results in the same.

    At this point i got there to check the machine.
    PS19 tests ok, but the motor M36 will not budge to move the shutter.
    Used IO 55-00 thru to 55-05 with no moment in or out of home position.
    Dissembled and check that assy and looks clean and ok. Shutter moves smoothly.
    All wire continuity was checked from the board to the sensor and motor.
    Next i checked for 24V and that was present on both sides of the ICP so the motor driver is getting juice.
    At some point i could feel the holding torque on the motor. The motor itself is fine.

    It will give the error on startup even before the transfer belt starts to move.
    Could it be that the IDC sensors checks to verify that the shutter is open or closed?
    Does anyone know if it will run with out the shutter installed?

    I also disabled image stabalization using the soft switches in hope to get a list print or test patern out of service mode.
    Engine wants to starts and the the code pops up.

    Any advise please.
    Whatever

    Re: C1100 error C2236 and C2237.

    On old machines of the same engine type the shutter does have to move or it will error out. I think I'd replace the patch sensors next. =^..^=
    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.

    Re: C1100 error C2236 and C2237.

    You could try without IDC shutter, i have seen c1085 works normal without shutter.
    I have expirienced bad developer could cause problems , lot of toner spilling inside machine arround developing units, color registration errors,charging potential error...
    Meanwhile developer and drum counter was at 60% ,output quality looks ok but get errors after few hundreds clicks.
    If you can try replace complete registration unit (sensor stay/lower assy A5AWR72300)

    Jip that said tech went back to fit the IDC sensor assy and shutter motor with no luck.

    Nothing worse than a tech caused error.


    My advise to him now is to take the entire cradle and the control boards he has with him to a working machine 300KM away...

    Sorry Allan, hijacking your post to ask if blackcat received my messages

    Re: C1100 error C2236 and C2237.

    Ok so the IDCS assy got replaced with no luck.
    Finally got the go ahead to test the PRCB's original and the replacement tested in a working machine.

    Both boards are blown with no ICP blowout. Both boards gave C2237 testing them.
    The give away is the fact that the code pops up after restarting the machine with the ADU unlocked and the drum cradle pulled out.
    Machine also does not state door open.

    The original code that made them change the print control board was a fuser code C3917 i think.
    So if it was not the shutter sensor shutter motor or the IDCS assy that shorted/overloaded the board then the bug that has blown 2 boards now
    would still be present.

    Testing the harnesses for shorts will take some time to do referencing the diagrams as i do pin by pin...

    Something in the back of my head is thinking its not even related to the shutter seeing that all those components seemed just fine.

    And thoughts on this?
    Whatever

    Re: C1100 error C2236 and C2237.

    Good morning Allan. Certainly the short is still present. I have come across two short problems in large machines. In a C8000, it was a broken wire and another wire tightened with a screw that cost 04 repairs to the ADUDB board and almost a month of work.
    The other was in an 1100, which also cost 03 repairs in PRCB and almost a month of work because of a developer that leaked across the machine and internally soiled the connectors.


    In both, I had to dismantle practically all the lashes and make point to point until I found the error.
    Nothing like day after day

    Jip there is a couple of hundred wires ends to test...
