Printer Repair Questions? Ask IT Technicians for Answers ASAP
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
You're on the right track, this is generally caused by some internal contamination, but not by the rollers specifically. Open the top lid over the adf and blow it out with compressed air.
Then lift the mid lid (over the glass) and clean the glass on the far left thoroughly, as well as on the underside of the lid. Focus on the thin plastic strip there (which is what forces the page back into the output tray of the adf), this is usually where the problem comes from; be sure to clean both sides of it, as dust and grease tends to build up and get trapped in there, causing the lines.
Let me know how that works out.
