Rainbow stripes on color print/copies KM3232

[Zookeyman]

Striping the full image and not the borders/margins. all colors, not pin fine lines but more faded in and out colors and differing widths depending on the color needed at that part of the image. At KM's suggestion, I replace the HV 1 board in the back and no effect. KM also suggested that the main PWB, ALL 4 drums or the transfer belt could be the issue.....(not being vague are they? )
Any one seen this? and what repaired it? I can't just start replacing parts...

I know, I haven't been able to up load a decent pic as I no longer have an San Disc to send the print to, and my phone camera just doesn't do it.
If someone had this, they would know exactly what I mean even with out a pic.
I am trolling for that person(s) that had seen this as K/M has a sample AND still no help other than "start replacing parts"
Thanks for the response.

Re: Rainbow stripes on color print/copies KM3232

You should start by running the U089 half-tone test patterns, all four colors (CMYK).

From your description I would suspect one or more color issues, but there is no way to narrow it down until you print the test patterns. When you've posted scans of the test patterns I can provide some useful advice.

I think you may be missing something about Copytechnet. We are all volunteers here. As a result you'll get the most information from the most people if you don't criticize the people trying to help you. Just a friendly suggestion. =^..^=

Hello Blackcat, I have run test pattern and sent them to Kyo for their review and recieved the usual responce, start with part "A" and replace through part "Z" till the issue is corrected.
Um, I am confused about the criticizing.... Going over this, I am not seeing this? I've been on this board for a few years and have helped and been helped(used to be Namikuz), so I am aware of how things go. polite gets in like, as does being snotty.
Sorry if I seemed rude, though I'm not sure where?
Thanks for the response.

This is the best I can do for now as my boss is still in California and the San Disc with the test scans are locked in his office. black does it also on test.
Thanks for the responce.

hi,

indeed the Km is right .
this has something to do with dev/dk units.
nothing with Transfer belt.

Re: Rainbow stripes on color print/copies KM3232

This may or may not help you, but I had an issue that I described as "rainbow", but it looked a bit different than yours (mine were fine lines). I, too, started replacing parts, but the final fix was as simple as cleaning filters. Dont' know if this will help your issue, but it is something to try without ordering parts.

The color sample really is like the gray and black, as far as the shading dark and light goes, it just is not showing well in the upload...

Re: Rainbow stripes on color print/copies KM3232

At least with the black, it's primary charge. Just replacing the primary charge roller, and performing a color calibration will clean up the black. Watch for the pattern crossfeed at 38mm intervals to give it away.

If you see a similar pattern, but it's at arbitrary intervals, you've probably got seizing developing unit.

Address each color individually. Make sure the last thing you do is the color calibration. =^..^=

Thanks to everyone for the input. I'll try these and have a go at it.

Re: Rainbow stripes on color print/copies KM3232

last time i saw that sort of a problem was the dev unit issues they had. That was a few years back when the white bushings cracked giving banded copies but as far as im aware that was fixed a long time ago.
