Print Image Quality Problems
Black Spots on the Page
The following characteristics define this print image problem:
• There are spots of toner scattered randomly across the page. The
spots may be few and isolated, or clustered into larger spots that
have a rough texture. If the back of the page is also dirty, skip
this procedure and go to the next image quality procedure—
”Back of the page is dirty”.
• The control panel does not display an error code.
The following procedure guides you through multiple actions that
may solve this print image quality problem. Proceed one step at a time
until the problem is solved—you may not need to complete the entire
procedure. If one of the steps in this procedure corrects the problem
but the identical problem returns in less than 50 prints, call for service.
1. Open the paper trays and check to see if there is any toner inside the trays. If there is toner
inside a tray, remove and clean the trays, then replace the paper with clean paper.
A paper jam can cause a small amount of toner to contaminate a paper tray.
2. Print 10 blank pages.
Printing blank pages can clean the printer system of small amounts of toner that may have
contaminated the paper path as a result of a recent paper jam.
3. Remove the toner cartridge and inspect it for small pieces of paper that might be stuck
between the drum and the toner cartridge frame. Carefully remove the pieces of paper. If you
cannot remove the paper, replace the toner cartridge with a new one.
When you clear a paper jam, a piece of paper may tear off and lodge between the drum and
the toner cartridge frame. This paper scrap creates a channel that allows toner from the clean-
ing system to leak out onto paper as it passes through the printer.
4. Call your service technician.
This image quality problem may be caused by a malfunctioning or broken component that
requires service.
