Re: Need help

Definitely sounds like a registration issue, however the samples you provided aren't that great. Did you run all adjustments and calibrations?

Yes, I think it's the colour registration issue or a damage developing unit or a damage toner cartridge. I did run all the adjustments and calibrations and the magenta shadow disappears then after some few minutes it appears again. The b&w printing is okay but it' only the colour printing that's giving this issue.

Thanks for your clever reply. This will help me to examine the machine more better. I called the technicians to have a look at it but they are not intelligent then you all here.
I have corrected this technicians two times and I know for sure that there not that experiance.

Re: Need help

ok .. what are the life counts on:
drums
dev
belt

are you using OEM genuine toner

OR

compatible

have you cleaned the laser slit glass

is the machine clean inside

as Mario said,

run color calibration/registration

report back please

The drum, dev and belt life counts are more than 50%. Read my reply to Mario's post. It is a registration issue or damage dev or cartridge.

Great I'm glad you are getting closer to the source of the problem! Phil had a good point that I missed in regards usage of consumables, but sometimes components fail even if they have plenty of life left. Focus on the rotation of the particular color that's having the issue, try replacing M with used unit to discard if problem resides on copier or image units. Cheat front cover and check for any abnormal behavior. I believe the waste tank covers the image units on these models can't remember from top of my head, and if you have firmware I'd bring it to latest version but only update 2 versions at a time from current one to avoid messing up OS.

Not likely a toner... dev or drum unit would be my quess

Thanks Mario,

I did check the front cover and realised that the cyan tube has some ink leaking from the tube. This may be the reason why the magenta and yellow ink is more noticeable on the print. Cyan is replaced with magenta on the printed paper. I think I found the problem now. Thanks for your time.

Phil B, Thanks for your time as well.

It was great sharing your ideas here. Very much appreciated.

Correct.. TIME that the consumable has been in ( not used ) and actual rotations.
Time idle can do great wear.

Looking at that sample, I see no cyan at all in the picture. After reading your post above, it sounds like you are saying that someone put a magenta toner into the cyan slot? Not sure how they managed that, but that certainly would create an issue with the registration as the copier would see magenta for both the cyan and magenta patches.

If indeed someone installed the wrong color, just vacuum out as much of the magenta as you can from the hopper under the toner bottle, install the correct color and run full halftones of cyan until the magenta in the dev unit is replaced with cyan.
