Strange iRC3200 Yellow Developer Issues

[Jake292]

My machine seems to be very hard on the yellow developer. Currently I have about 3k copies on an entire set of new oem developer units and once again yellow is giving me trouble. It seems to randomly leave a haze on basically the entire sheet or it will have a "cloud" of yellow somewhere on the sheet (lower left in pic); while others are perfect. Performing the auto-gradation adjustment seems to help for a short time but, it always comes back. The sensors above the itb are clean and we only use first time oem developer units.

Any help is greatly appreciated.
Thanks.

Are you running full coverage, heavy density copies

-------------------

is that a glass copy ?

it's all about % use of color usage /coverage and not the "K" Reading

in
COPIER>OPTION (Level 2)
COPIER>OPTION>BODY>Y-PTN
set to "0"

Re: Strange iRC3200 Yellow Developer Issues

I would call the coverage below average for the vast majority of pages. The others have mostly black text and maybe a couple small photos here and there. It's not a copy from the glass; its a pdf stored in the mailbox and recalled for print. Just changed Y-PTN to 0 as instructed, will report observed changes.

Thank you very much.

Re: Strange iRC3200 Yellow Developer Issues

Since changing the Y-PTN value to 0 it seems to have the rogue yellow problem less often but, does still return. The problem seems to creep up randomly. No discernible pattern of running time, or type of image. And the yellow defect is seems random in it's appearance too. Sometimes the size of a baseball at the bottom of the page, sometimes stretching up the entire page about 2-4 inches wide, some. Often with the very next sheet being perfect. I haven't been servicing color machines very long, mostly large black and white machine. I've tried a couple things that seem like it should be related; reseated the yellow developer unit, cold reboot, running the books in 50 page sections and allowing machine to stop before starting another.

Still looking for more reliable image quality for it.

If u know how ? Pull out the ITB UNIT> & remove the ITB SHEET>

what u will be looking for is the YELLOW PRIMARY TRANSFER ROLLER POSITION/
make sure it is sitting/snapped into \both ends & rolls freely-/ those black small holders crack or spring pops out of position"/
have seen weird issues when roller is out of position-- check them all

causing the Y Primary T Roller to push up on an angle inside ITB SHEET > pushing image drag on Y DRUM>
on this series the image is transferred from Drum >to ITB SHEET by the Primary T Rollers> image is then transferred from ITB to paper by the ITB internal secondary & external Transfer Roller


if this is only on a YELLOW ISSUE
u can also try to Swap the Lasers> (Y to M) to see if issue transfers over to another color

Re: Strange iRC3200 Yellow Developer Issues

After a while of the problem not seeming to go away, I cleared the DC-CON memory. After that it seems to give at least 400-500 beautiful copies before returning, clear again and beautiful again. Now, am I reading meaning into a random, sporadic issue? Or is there something stored in the DC-CON that would effect bias voltage, etc.?

I hope u had a P Print printed out, so u can replace the DCON settingd
?

Re: Strange iRC3200 Yellow Developer Issues

Yes, had a DCON P-PRINT in hand. Opened the machine up today and inspected ITB Assy, everything looked physically alright. I brushed off the toner dust, etc. Slipped the ITB off and popped out each primary transfer roller, all of them looked fine. The black primary transfer roller connectors seem a little loose, had to push it back into place after turning ITB Assy. right side up. I did notice the yellow primary transfer roller position is not the same guage wire as the other locations on the ITB Assy. That was the only thing that jumped out at me. Seems like that could be what is interfering with continuity but, enough to result in this problem? I dunno. Intermittent millisecond(s) long loss of continuity on yellow primary transfer roller? Unless anyone suggests something else, I think I'll measuring continuity tomorrow and see what improvement I can make.

Thanks.
