I'm currently troubleshooting a strange issue on a Muratec MFX-C5590 (Konica Minolta C558). Please see the attached sample. Copies are fine, print jobs from the User Box are fine, meter counts are fine, management lists are fine, gradation prints are fine, but network print jobs have lines, demo page has lines and configuration page has lines. I've never seen this before. I can restart the machine and things go back to normal, but the issue comes back. Hotline seems to think it's the MFP board, but I wanted to see if anywhere here has been down this road before.

Re: Has anybody ever seen this before?
Image processiing for scanned images is done separatly from the print processing, however the image procssing board controls both. I would start here, but it's gonna be a big $$$ as everything is done on the main board. E -
Re: Has anybody ever seen this before?
Not seen that exact pattern before, but have had similar issue. Remove the RAM, clean it with alcohol, and reseat it. If that doesn't work try replacing the memory.
I've seen RAM cause diagonal lines similar to what you have. Another time it looked like snow/static on an old TV, but just in random places on the page, and then only from internal prints. Copies and regular prints were fine.Comment

Re: Has anybody ever seen this before?
This is very interesting. Never seen pattern like this but run full diagnostic and start from there. Unfortunately as Ed said it's gonna be expensive, my guess is also MFPB.A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.

Re: Has anybody ever seen this before?
I have seen something like this from a bizhub C353. It was ONLY the bird test sheet. All other functions were normal. Since it was so narrowly limited I never looked more fully into it. =^..^=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: Has anybody ever seen this before?
This is a bad internal memory of the MFP board.
Frequent repairs.

Re: Has anybody ever seen this before?
Remove the dual scan image processing board at test, had similar and was ok when DSIP board was removed.Comment

Re: Has anybody ever seen this before?
Have had some kind of issues on C451-C452 series machines, some one above mentioned the internal RAM and I recon the same. But replacing the MFPB seems logical and you can try on the replacing the RAMS later....

Re: Has anybody ever seen this before?
I replaced the MFPB today. I won't know for a while if this fixed my issue or not. As of now, things are printing fine.Comment

Re: Has anybody ever seen this before?
So the customer called back today and reported the same issue. I'll stop by tomorrow to confirm, but any other things you guys can think of that I can check on while I'm there? MFP board has already been replaced.
Thanks in advance.Comment
