    1. All missing powder should lay in WTB.
    2. Don't just replace powder replace developer unit. K one is dirt cheap.
    This is very important new unit will do new release and will initialize machine readings for proper tune up, calibration and gradations. Otherwise you're asking for troubles.

You may get some results that way waiting for new bushing and K developer unit.
    Thanks for the assistance,
    I'm guessing the bushings could also be changed.
    If so can you provide me with the part number
    ?

    Error codes C2551, C2553, C2555 and C2557 are related to abnormal low toner density.
    Root Cause
    Toner is leaking from the toner seal onto the bushing of the transfer screw.

    Workaround/Fix
    Replace the toner seal (p/n A5C1RA0000).

    I've had luck with just removing the white part and cleaning it and the auger chamber out. I've only come across this issue on 2 machines (both on the black hopper) and have never replaced a part yet. The one I remember the most happened at about 80K pages. Since cleaning, it is up over 550K now and never had the problem come back.

    Even if it was cleaned out as a temporary fix, it should last quite a while afterwards.

    Re: Pattern on prints shows up on black C454e

    I've searched for the part number and still haven't been able to find a seller of the part. There's this store I usually get my stuff from it's not showing.
    Kinda strange to not have another place selling parts,.
    Anyway will share the results of the cleanup plan is to work on it tomorrow.

    I once had ALL the develop unit look the same. Need to replace the high voltage card & then new dv units..
    Old dv unit is dead. The device cannot adjust the defective one. Wonderfully expensive...

    Thanks to @Synthohol and others who really assisted
    Well today i cleaned out the bushings, thanks again man for the illustration

    if you use OEM toner, there is developer mixed in with the bottle that replenishes small amounts that get trashed during normal use.
    it will balance itself eventually i hope.
    good luck!
