Question about Canon imageCLASS D780 All-In-One Laser Printer
We use a Canon ImageClass D780 copier. Lately when we use the ADF, there is a distinct black line all the way down the page. I have cleaned everything I can clean on the copier, and still the line persists. Is there anything I can do short of bringing in a serviceman?
Take a credit card and scrape the glass clean. You only need to clean along the right side of the glass where the paper passes through. Dirt that you can't even see will cause the lines.
