    hello, I disassemble those bushings and always clean them with a screwdriver, alcohol and rag, but to do it first, that day of the first intervention, I replaced the pcdu with that of another machine we threw away, with the consumables recently replaced, I'm getting the doubt that since it was an mp4001 maybe it has an outdated frame, because the old ones lacked a contact, however on Monday afternoon we replace it with another mp4002 that I have here ready, we after the third time we go out for the same thing, we substitute the complete machine, for company policy, obviously as long as we are not talking about a martini

    2a-1.pdf looks exactly like one with a partially clogged toner recycle unit.

    i already went out 3 times, i replaced opc, blade, ccroller, c.roller, developer, transfer belt, transfer blade, cleaned everything perfectly, development unit and developer, they are new 10k bk, comes from another machine we threw away
    Replace with new parts these machines have mag roller problems always need cleaning when replacing developer make sure mag roller is silver. And set up correctly

    When you swapping from other machines are you re setting up or are you just fitting then leaving if so there's your problems save time and money just rebuild correctly with new parts

    No, the PCDU I mounted, comes from a machine that the rental is over, it only executed 11k prints, from September, can I throw it? I disassembled it and cleaned it completely before bringing it as a customer, I repeated the installation process that is done by manual, since it was all semi-new, and clean

    The Developer Unit D009-3001, along with all the other PCU consumables, because it was broken, the whole did only 11k from September

    Indeed the photo makes it better than live..lol, however it was all complete free, aspirated all twice, in two days. I suspect to have mounted an Old Style frame, that without ground, behind, Monday I'll find out why we replace it with another MP4002, 3 interventions are too many for the same problem.

    Re: mp4002 dirty egde, only lateraly [SOLVED]

    hey guys, it was just as I imagined, when I replaced the pcdu, I was wrong to take it up, I thought it was that of a customer, and instead it was that of another, I practically mounted the pcdu with the old style frame, without ground of the unloading clochea, the machine, when under stress, electrostatically attaches the waste toner, and inflates the exhaust, as soon as it returns to an acceptable range of load jobs, the print returns good, thanks for your valuable advice
