    Docucolor 252 yellow streak

    Anyone come across this before?

    Tried swapping drums and dev tanks but still getting thick yellow band across top of copies/prints.

    Machine has recently been relocated and was fine before the move.

    The yellow band is on the rear of the transfer belt when I pull it out.

    Cleaned all ros windows.

    Any advice would be appreciated.

    Thanks.

    Hi, thanks for the reply. Wouldn't a dirty ros window just cause blank lines in prints?

    The machine was recently moved 500 miles with toners left in.

    I gave the ros windows a quick wipe, I didn't spend too much time on them because I didn't think it could cause the wide yellow band.

    Cheers.

    I didn't mean it was dirty, But it was faulty . Try replacing ROS assy.

    I see, thanks for your help.

    No contract on this device, don't really want to ask client to spend £600 on a part unless I'm sure.

    Yellow and magenta ros are same part number. How big a job would it be to swap these over? I haven't replaced ros on this machine before.

    Kind regards.

    There are two ROS units, one with K and C, and other with Y and M.
    I'm not sure if you could interchange those two units just to be sure if there is a problem.
    It's not too complicated to reach ROS, follow the documentation. But those flat cables could be pain in the ass sometimes.

    Oh OK thanks. They're different part numbers so probably can't be swapped.

    Thanks for your help.

    You can cover the ros window with black paper strip and see if the band appear again.
    I will look at the position of yellow drum and yellow dev. assy
