Konica C364 - suddenly fine stripes in the print

[technics1210]

Hello,
I have a c364. This always worked. Suddenly there are stripes in the expression.
See Appendix.
I've already cleaned everything without success...
As well the placement of the printout isn't quite right. the frame is not quite...

Do you have an idea to solve the problem?

Thx Technics

Most of the time lines like this are caused by a faulty PH unit (Laser) . Sometimes the ribbon cable going to the PH unit will cause this

remove transfer belt, clean both IDC sensors and replace the drum.
see where you are at from there.

If lines only happening with black then replace black drum.

Looking at the top of the page, where the date and time is, I'd say the printhead also needs cleaning...

Where can I find the IDC sensors?
I have some C224, I think the transfer belt is the same. I will test...

remove belt, slide shutter to the right and clean the 2 clear IDC sensor windows in the red circle areas.

If only with black, I would say K-drum. When with all colors the transfer belt cleaning blade.

Wenn nur mit schwarz, wird es wohl eine defekte K-Bildtrommel sein, wenn auch bei Farbe eher ein verbrauchter Abstreifer in der Transferbandeinheit.

Very common 'fault' Take out the black imaging unit & see if you can see the lines on the drum if you can then replace the black drum.

Like Markks said it's PH unit. So many fine lines all of the sudden can't be black drum at all.

Am I missing something here!? looking the the OP sample image, black lines on the prints is usually caused by the black drum. Especially if colour prints are OK.

White lines / deletions would be the printhead.

OP hasn't said what the color prints look like but yes with sudden appearance of multiple fine lines it is more than likely a bad PH. I've seen it multiple times. On rare occasion I've seen the ribbon cable cause this. As far as the PH being responsible for white lines or deletions, that is if the PH glass gets dirty.

I too agree print head or its connections. some further testing is needed.

Hello,
sorry about the late response.
I replaced the drum and the transfer belt, without success.
I think the print head is defective.
Is it worth repairing or better using the printer as a spare parts donor?
Thanks
