LazerJet CP1025 nw color printer prints stains on every paper

[Zavadic]

Hi, I have a problem with my hp printer. I wanted to print many papers and after some of them were printed, some stains started to appear on the left side of the papers. I also tried to print a cleaning page, but those stains were on it too. Is there any cheap and reliable way how can be those stains removed? I tried adding some photos but your editor probably doesn't like them. 

Thank you for advice,

Sound like it's the drum is defective, but post one or two ptotos will be more helpful.

Cleaning page

Here is the picture of cleaning page, sorry for not adding it before. Maybe there was some problem with connection to my computer.

It looks like is drum 's problem.

Take drum out and check the surface of the same side it might have a defect or friction if it did then you need to replace it.
