HP Color LaserJet CP3525 issue

[AleksanderA]

Hi!

I got a big old LaserJet printer. It has the following issue (image).
Can anyone give me a quick advise, how to handle a problem like that?

Thank you very much!

Regular stain could be caused by the rollers damage and magenta toner leak. Since your printer's old, both the drum and toner cartridge could be wore down after years service. Firstly change a new magenta toner cartridge and print test page. If spots still appears but turn into black, then clean the drum. If problem still, all you need to do is exchange the drum.
