Pattern on prints shows up on black C454e

Re: Pattern on prints shows up on black C454e

ok let me see if I can get a bushing for the unit and also a new K powder

I don't think there is enough in there to get any reasonable prints to be honest.

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.

I don't recommend putting another developer into machine especially from other brand. Besides your new developer unit would quickly finish in WTB if Synthohol is right(like 90%). Your best bet for short time is to take developer from WTB with help of magnet then fill up developer unit remove bushings and clean them or atleast one for black unit. 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
?

Re: Pattern on prints shows up on black C454e

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.

Thanks. Too.
I am trying to get some developer back on Island. Then will confirm if this work.
I'm also going to try another user here comment here where they say to try getting the developer powder from the WTB until such time.
I'm in my 'By all means necessaryv mode thanks

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.

Re: Pattern on prints shows up on black C454e

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
And I added some dev powder back into the unit and I'm getting blacks
Don't know how long it may last but I'm hoping for the best till the main printer is back up and running then can take a good look at this one
Please see the scans of the print test
good prints oct 19.pdf
thanks again all

Re: Pattern on prints shows up on black C454e

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!

Good result!
Regarding the white bushing - worn one can cause c2557 abnormal low toner K density, but then machine will stop and (in theory) should not cause developer loss. K output will be faint as toner density will be 1% or 2%.
When you take out the bushing and look inside, you will see toner. In that case replace it. If it's clean then it's not necessary. Replace with modified ones - metal bearnig inside.

Regarding developer - permanent magnet on magnet roller should hold back developer, and bias voltage from HV board should hold back toner.
In theory HV board failure will result in solid black (or colour) image (no Vb or no Vg). It will not suck out developer. Voltages can be checked in State confirmation --》 Table number.
Only sparks from worn drums can take it out little by little.

Using OEM toner will recouperate developer and after few thousands prints brush on magnet roller will be perfect again.
