I have a Docuprint CM205b (cm205) laser printer. I notice my prints had lots of lines, and I tried to clean the back of the printer.
I notice that a lot of toner is collected at this area (see photo) on top of a film. It looks like a piece of rubber is broken. Photos below are taken after I vacuum off the toner.
Can someone please advise on what broke ? Should I clean the film ?
