2 new developers and drums installed. Uneven developer on mag roller on both new developers. No codes or any other CQ issues. Any help appreciated.

Re: TASKalfa 2552ci sloped yellow banding
You cannot swap yellow drums between machines or you'll get CQ issues. You can only replace (yellow) with a new drum. Were these new or used dr's & dv's?
Also, what simulations are you running after replacing drun and DV units?
Edit: I know you said 'new' but many times a tech will say 'new' when it's really just a different drum out of another machine.Last edited by BillyCarpenter; 12-19-2022, 07:11 PM.Adversity temporarily visits a strong man but stays with the weak for a lifetime. -
Re: TASKalfa 2552ci sloped yellow banding
An image quality sample would be nice. Something like this?: =^..^=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.

Re: TASKalfa 2552ci sloped yellow banding
Gosh Billy, I swap drums around all the time. Especially for troubleshooting. Swap that baby and see if ya get change of state. Same thing for developer units.
Many times I have swapped a damaged drum in a machine out in the field with the yellow drum to get by until I can get back with a replacement. Run image adjustment (U464, U469, U410) and its good until I get back. In the office I swap developer units (and sometimes drum units) to see if the problem follows the unit or stays in the problem machine. The thing one has to do is put them back where they came from. There have also been times I have HAD to pull a drum or developer unit from a machine in the shop and deploy it out in the field.
However, you cannot take a drum or developer unit for a 2552ci/3252ci and swap it with a drum or developer unit with a 3552ci,4052ci,5052ci, or 6052ci. The drum and developer units for the 25cpm and 32cpm machines are different from the ones for the 35cpm thru 60cpm. Fuser units are different on these xxx2 series as well. On a side note, the black drum, developer, and fuser in the color 35cpm thru 60cpm machines is the same on the black 40cpm,50cpm,and 60cpm machines.
stsacer, It would be nice to see some samples of the trouble your having or a picture of the troublesome developer unit see what is going on.Comment

Re: TASKalfa 2552ci sloped yellow banding
You can swap every color developer around (between machines) without issue. You can swap all the drums around save yellow.
This is from my notes that I got from KYO_OEM and from my research it holds true.
Don`t touch the yellow drum marked with a yellow dot.
Don`t use it in other system on yellow position, if it would done in past you can get image quality problems because the yellow drum would used for internal system back up data.
We also have had a few cases with C9540 because all 4 drums would swapped mistakenly after cleaning.....
(yellow on BK position, magenta on cyan position and so on.)
If this kind of DK is broken, use new service DK unit with red mark.
Maybe someone else has heard this about yellow drum?Last edited by BillyCarpenter; 12-19-2022, 11:38 PM.Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment

Re: TASKalfa 2552ci sloped yellow banding
I went further back in my notes and found a little more info on the yellow drums.
The original yellow drum that came in the machine will have a yellow sticker with a black dot. None of the other color drums have any color identification. Only the yellow.
If you order a new yellow drum from kyocera, it will have a yellow sticker with a red dot.
See picture below:

Re: TASKalfa 2552ci sloped yellow banding
Would not let me download 2.3M Jpeg pic. Will scan it to PDF and try again. BTW I have also swapped drums to troubleshoot and/or stall for time. Be careful RFID stores CQ settings for that drum including counter, and when I put new drum unit in it may write that info to the new drum. Learned real quick not to HOT swap. ALWAYS turn completely off! Stay tuned!!Comment

Re: TASKalfa 2552ci sloped yellow banding
That looks like a developer problem to me. More information is needed. You said you replaced the DV & DR twice. Were they new or out of another machine? What simulations did you run after replacing? What's the copy count on the machine?Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment

Re: TASKalfa 2552ci sloped yellow banding
That look like a drum, main charge roller issue. The spiral is coming from the main charge.
2nd
The yellow original drum that came with the machine is different, and should not be switched in different locations.
Unplug the machine from the wall when replacing the units or the counters may not get reset.

Re: TASKalfa 2552ci sloped yellow banding
With all due respect, Billy, I don't think you are correct about about this.I went further back in my notes and found a little more info on the yellow drums.
The original yellow drum that came in the machine will have a yellow sticker with a black dot. None of the other color drums have any color identification. Only the yellow.
If you order a new yellow drum from kyocera, it will have a yellow sticker with a red dot.
I looked through the latest parts manual (Revision B) and on pages 60-61, there is no reference to a separate yellow drum. All the drums in the models 2552ci and 3252ci are DK-8350 (P/N 302L793051). I found this true as well in Technical Bulletin #1 Revision 4 for these models. No where does it list or mention a separate drum for yellow. There is a separate developer listed for yellow.
I had to my Kyocera tech rep about another issue today, and I asked him about a separate drum for yellow for these models. His first response was "You're kidding, right?" He said he never hears of such a thing. Any drum for these models (DK-8350) can be used for any color at any time. He went on to point out that if it was a separate drum just for yellow, it would have its own part number.
So I think you may have some incorrect information.Comment

Re: TASKalfa 2552ci sloped yellow banding
My information could certainly be wrong. I got the information from KYO_OEM and he's always led me in the right direction Do you find it the least bit curious that the yellow drum is the only one with an identification mark? And toddanderson (post before yours) just said the same thing.
I also trust you so now I'm unsure.

Re: TASKalfa 2552ci sloped yellow banding
The original drum that comes with the machine is different, All the replacement drums for all colors are the same. see the attached pdf
