Fig. 6-8 Dark Stripes or Toner

Stains

Printed pages have white spots in black text and graphics area.

Recommendation

Turn the print density dial counterclockwise for lighter images and clockwise for darker images. It has been factory set to the middle position. See “ADJUSTING THE PRINT DENSITY” in Chapter 5.

You may clear the problem by wiping the scanner windows with a soft cloth. (See “Cleaning the printer interior and Drum unit.” in Chapter 5.)

If the same problem occurs and the Drum lamp is still on after cleaning, replace the drum unit with a new one.

∙Clean the printer interior and the primary corona wire of the toner cartridge. See “Cleaning the Printer Interior and Drum Unit” in Chapter 5.

∙Make sure that the tab of the corona wire is at the home position.

If the same print problem occurs and the Drum lamp is still on after cleaning, replace the drum unit with a new one.

Make sure that you use paper that meets the specifications. Rough surface or thick media can cause the problem.

If you still have the same problem and the Drum lamp is on, replace the drum unit with a new one.
