    Images on internal prints and copy job and picture on tbe page comes out full black on a 808 almosr 3 million on it. The developer and drum have been replaced the laser unit. Hv1 HV2 and HV3 have been replaced. Fw up to date. Ran stabilize initialized. Can't run gradation stabilize not good p-9 drum/dev and p-5 idc front oil can message in service mode. Anyone got any ideas on a fix? Going there with an idc sensors see if that changes anything. I'll try to get a picture uploaded I keep getting a error on my phone

    Are prints, scans, and copies all equally affected, or which combination? =^..^=
    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.

      Yes they all look the same text look bold and picture like the bird on the internal print comes out as a black square. Doesn't matter if it's a print copy or internal print. Have not tested scans. Konica things the gradation is messed up somehow because even if I run a halftone at 1 out of 256 it's just as dark as 256

        It's very simple, you are not opening the AIDC sensor window of the transfer belt. There is a cam modification for that. Temporarily leave it forced open, make a gradation adjustment and you'll probably fix it.

          Yeah you are right when I showed up this morning to replace the idc sensors I found the connector disconnect problem from one of the last two tech here within the last two weeks, plugged it in all good now that I'm thinking about it that makes alot of sense just don't know why or how that was unplugged while under a cover that protects it. Thanks for the response everyone
