3253ci color issues after transport

[jhide]

dear community,
I was hoping you could help me troubleshoot the following issue. After transport of 3253ci taskalfa machine to a new location, the color prints are showing defects (see attached scan). We have excuted drum refreshes, calibration, etc but the problem remains. Any suggestions what could cause this and how to fix it?

additional question - Is it possible to access the service menu over the VNC connection? I have tried multiple times with vnc and can access the screen of the printer, but Im unable to access the service menu when entering the code. The code has not changed from the default one cause when Im physically at the machine it works without any problems.
regards

looks like belt problem, have seen it in case of old belt.
Check contact springs on transfer high voltage pwb and both springs behind the belt on rear frame in upper left area.
Service mode not available by external connection, only available on production printing system TASKalfa PRO 15000c.

Your yellow and cyan has tiger striping in it. Your image registration judging from the color test page text in the top right. Not sure if the original is supposed to look that way. The rest does look fine.

Pull the DV units out and rotate them. Can you see the mag roller in a similar pattern to your faded out parts on the page? Whenever dual component DV units are depleted of DV they don't form a uniform brush and make that tiger stripe pattern. Ive seen on the older sharps when the drums pulled DV they stuck it to the belt and put it in the waste toner so the failure was pretty clean.

Try doing a U089 color belt chart. Would give a better picture. Ive never seen a transfer belt make those marks but i haven't been working on Kyocera long enough. Let us know what fixes it.

Sorry for my delayed response but I was only to get to the printer this weekend. I can confirm it is not the transfer belt because I have tried with a spare one and the issue is still there
I have run an U89 color belt test and I have scanned the result. See attached.
I have also pulled the DV but don't see the stripping that is showing on the print-outs. I'm really wondering how to fix it.
If anyone has any ideas, please let me know.

Those are definitely auger marks from the DV units. You can take them out and shake them gently side to side to see if it evens the DV out. You could also perform a DV refresh. These may temporarily resolve it, but you might have to replace the DV units.

I have alreay perfomed a couple of DV refreshes but it didn't improve at all. So maintenance kit 1702NP0UN1 with new developers and drums is the best solution?

You don't really need the drums, but depending how close it is, you could install them. The developer level is low or shocked, so you're seeing the augers spinning in the DV units. I had the same thing on a 6062ci that had about 20k color, but 1.2m B&W. The colors weren't being used enough and caused the issue.

Those U089 sample sure do look like depleted DV but what are the chances of all 4 units doing it? Seems pretty sus. 1 bad drum pulling down the charge voltage on the other drums?
Ive seen a Sharp do that, the main charger (grid/sawtooth) was arcing out and dragging the high voltage down on the color drums making very solid full bleed pages at random. Can't say ive ever seen a Charge Roller equipped machine do that though.

I can only assume something happened when they moved it. In my case, the black DV was fine. The colors were the issue, but that was due to a charge problem from not being used but turning.

Machine did sit for some time not used (probably 1year in office space). 31k only on b/w and only 5k in color. I will order 3 new DV's units and hopefully that solves the problem.
I will keep you posted.

Dark Helmet - Is there anyway of identifying which DV has gone bad?

From your samples. All of them.
Are you a Kyocera Tech or a end user / IT?

Kinda like you already said DH....

[jhide]

I'm an IT Tech. I have multiple kyocera machines at small business but the issue described above I had never experienced with any of them.

Who moved this copier? Is there a chance it was transported laying down on backside? This would explain how DV units got low on developer material.
Another possibility that during travel truck went on gravel road (or something like that) and this would compact toner (and possibly developer) especially after been sitting without use for extended period of time (covid and nobody goes to the office). Have you tried to pull toner bottles out and shake them thoroughly? With this low meter count chances are toners original install. Plus if they are compacted inside this could ruin new DV units and be back to stripe pattern.
