Strange artifacts on page when copy or scan C258

[wseyller]

C258 with firmware at latest.

See attached picture. I blacked out sensitive info but the square artifact in this case in cyan color. Other colors have been seen. If doing black only the patch will be black.

Has been happening for a few weeks since customer got copier but doesn't happen very often.

Originally it was only seen when making copies. Was never seen on scans or when printing from driver.

When testing internal pages I could never duplicate it. I did reproduce it once when making a copy.

I intialized the copier and set it back up from scratch per the setup instructions.

Since doing that the issue is now seen during scan but so far not copies or prints.

Going to open a ticket with KMBS on monday but wondering if anyone seen this before.

Looks like a corona grid to me but that would not be seen in a scan.
Weird. Please let us know what ssd says!

Seems you have microbial fungus growing somewhere in the machine.
I suggest using pesticide.

If it was only on copies I would say Its probably the transfer not cleaning itself off and leaving the adjustment chevrons on the belt

If you never found any prints. It should be a image read problem?

Does it happen on both adf slit glass and other side of the glass ?

Re: Strange artifacts on page when copy or scan C258

Only for sure is single sided thru adf with dual scan adf installed. Customer doesn't use platen glass or two sided enough to know if it happens in those situations. It is hard to catch it. It happened to me only ever once.

I'd personally be trying a new mfp board, but I understand you not wanting to jump to that immediately due to the horrendous cost. It does look like image data corruption / memory.

KMBS thinks it is image processing issue.

This one has extra ram. They say try new ram, then mfp and HDD.

My manager said to just replace it all. Doesn't happen often so have to play the waiting game to see if it fixes it.

I've had similar on 452 and RAM was the issue.

For what it is worth, that looks a little like what Ricoh calls a process control pattern, something the machine does to make sure the colors line up and have adequate density.
So the part that cleans whatever KM calls the intermediate transfer belt (Ricoh) or electrostatic transfer belt (HP) may need additional attention.
Or I could be totally wrong and this is a useless waste of time. I only worked on analog Konicas. Sorry.
Although Konica was using toner patch based internal adjustments even back in those days, which I thought was rather fascinating at the time.

It happened with scanning too so nothing to do with transfer belt.

Rats, I missed that part, sorry about that.
