CLC 3220 magenta fat lines

[Esperanta]

Dear experts,

I have a CLC 3220 machine with 48k print/copy for now.
I have a magenta color issue, when print / copy.
I have magenta fat lines on the copy/print sheet; sometimes this fat line does not appear on the printed/copied sheets. These fat lines appear either if the print is full color or small percentage of color.

looking at your examples i would say you have either a faulty cyan dev unit or a faulty cyan drum (assuming it is a 4 drum machine) that is where i would start at this point in time

Whats the meter on this unit. And what kind of service has been done in the last 6 months.

Looks like drums for now.

[Esperanta]

the last service was before 6 months.

the misc show Y-DRM-LF 75, M-DRM-LF 110, C-DRM-LF 110, B-DRM-LF 115

What was done?

You can start with cleaning the magenta drum unit & the magenta transfer roller inside ITB assy. If cleaning fails then replace it both.

BOTTOM LINE IS=REPLACE ALL DRUMS AT SAME TIME/

Replace the M-drum or better replace YMC or even beter replace em all.

The problem is a bad or flat spot on the primary charging roller, the flat spot cannot properly charge the charge the drum, on that side toner is attracted and causing M background.

good point>>


those Primary charge rollers need to be inspected/ they pop out of place on ends/ plastic ends also break/

also when coated with toner , they do not function well
