MX-3100 Line on prints CMY only

[Jack79]

Hi

I am looking for your advise.
Internal prints from 64-1 each colour give nice printout (no issue and nice quality).
Documents sent from computer or copied from glass give (along short edge A4 paper) a line on CMY (K is not affected). Quality is fine. Line is always in the same place for all 3 colours.

Internal prints do not print this line.
Could you advise how to fix this issue please?

How old are the CMY chargers? I assume you already cleaned all components that could be a possible cause.

Thanks for reply.

I do not know its history but according to data from the machine C maintenance has been done 8000 pages ago.

If it charges then why internal prints are fine and why line is printed at the same place for all 3 colours?

I have not done a lot yet as I am confused. Because I have not noticed that K is not affected I checked transfer belt and looks fine but there was a peace of paper which I removed and second transfer belt is fine too.
I have checked Y and M developer and found nothing. They were a bit dirty but quite normal.


UPDATE:

I swap all 4 dev and drum units. Problem persist. So it is not drum/dev issue.

Run skyshots in the single color mode and see if you are getting void areas in any of them.

If one color has a void area it looks like a line in your color copies as the colors are not mixed properly.

Also try changing out the transfer belt assembly. I'm still assuming all components were cleaned and checked including the optics, need to rule out these things, good luck!

Re: MX-3100 Line on prints CMY only

I've encountered in MX-3110 the copies and prints have thin hair straight lines from end to end on all colors. The lines are horizontally on a portrait print and copy. I replace the CCD and the problem was resolved.

Re: MX-3100 Line on prints CMY only

Thanks for all your replies.

Primary transfer belt is not an issue as it was replaced too.
I will post some pictures on Monday.

This is not copy problem but print an copy.
It must be dirt somewhere. I suspect LSU.

Re: MX-3100 Line on prints CMY only

You description of symptoms does not make sense. If it was LSU (or any other part of the engine) you would see the same lines equally on internal prints, network prints and copies. If you truly are not seeing these lines on internal prints, could it have something to do with the fill density of these internal prints? Try a 15% fill for each color individually (PDF document attached). I think that you'll find that these lines are present on all prints. Please attach scans of what you get.

Re: MX-3100 Line on prints CMY only

I would have to say something in the optics, clean all mirrors, remove lens cover and clean both sides of the lens, and front of CCD my 2 cents

Hello

I have attached some samples as a PDF files, Please see line on the bottom part of page.

4block - show each 4 blocks (2pages) CMYK and you can clearly see line (on the bottom) on CMY

15 percentage from blackcat. The scans are bad as I am not sure how to make a good scan. Anyway C and M shows this line (bottom). Y and K do not print this line.

Internal prints. These scans show internal prints from the machine. The bottom line is not printed on internal printouts.

Please ignore thick line on top of the scanned documents. This is not on the page - scanner optics are dirty probably.
Also this is not a scanner issue. This line does not appear on any (not defected of course) scanned documents. Here are presented documents which were printed with this line. Print issue.

Try interal print with

SIM 64-1

A 11
B 2
C 2
D 155 (this is the density, higher is darker, lower is lighter, max is 255)

Jack

have the files you are printing been scanned by this machine? it makes no sense that internal prints and computer prints are different only difference is one is stored on the PC and the other is stored in the machine. Are the internal prints orientated the same as the computer prints? (LEF or SEF)?


did you check your scan glass on the copier ADF?

Re: MX-3100 Line on prints CMY only

Phil my English is bad but saying internal prints I mean prints from sim 64-1 in this case.
Scans posted here are from this machine.
