    Re: C280 J-3003

    There was burnt toner that presumably fell off the fuser onto the shafts of the reg rollers right next to their bearings. I did a quick clean up and added some WD-40. The reg roller had some initial resistance when you tried to spin it, but now it's gone. Otherwise it behaves the exact same way it did before.

    Finally, there is only one finger on the belt, seems that the machine had been modified according to the bulletin tbs attached.

    I haven't tested it yet but I may disassemble the whole reg assy and give it a more thorough clean. Is there anything else you think I should also check?

    Thanks.

    No. Your is UNmodified, new ones have 3 claws. Also you will need that black plastic guide - item 19

    Sorry, I got confused and thought that having one claw meant that I'm good. Thanks for the advice, I'll check if there's somewhere to buy these parts..

    **NOTE I wouldn't suggest using WD40.. it is not a rust preventive.. it is a WATER dispersant may I suggest you try Triflow oil.. it has teflon particles in it.. give longer protection.

    If you need it to penetrate try Marvel Mystery Oil, but it vaporizes within a year and is gone.
    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.

    a Quick way to test is to put a small well directed and controlled amount of WD40 on those brass bushings.
    Not suppose to put lube there but you will know soon enough if its the registration roller ends and bushings that
    gummed up.


    Could be something else.
    Guys, allan said "Quick way to test".
    Means - just to troubleshoot before disassemble and clean properly.

    WD40 has been known for years to destroy BRASS Bushings.. it dries out the oil built into the bearing causing squeaks.. and wears out the shaft where the bushing rides...

    this was found out in the early days of the color units Both HP and Canon.. Ricoh came out a few years later with the same statement.

    I always disassemble ... clean and lube the bushings/bearings

    Paper that has excessive curl may not separate easily from the Transfer belt and will contact
    the separator claw. A jam may occur or the claw may be pushed into the Transfer belt creating a scratch or possibly a gouge.
    There are parts modification. See attached.

    I had once on a BH-C-360 a brandnew OEM TB with the famous 3 separators where after a jam the middle separator ripped the belt. Since than on all of our rentals I remove ALL separators, being one or three, and leave the TB completely without.....

    I believe this is SOP with most techs I know. It's a permanent fix for "Mustache on every fourth copy".

    Hehe done the same before. After needing a transfer belt replacement a found a piece of paper that must of been riding on the top of the belt for months.

    Sorry guys WD40 was bad advise. You will need to strip and clean anyway.
    Sanitizer for the job?
