Decline in Print Quality

Problem

Vertical black or white bands or lines appear on printed pages.

Horizontal black or white bands appear on printed pages.

Solution

The glass lens of the print head may be dirty. Open the printer to the upper position, remove the imaging cartridge, and locate the lens that runs across the inside cover. Wipe the lens with a soft, dry cloth that is free of lint. Do not touch the surface of the lens with your fingers. Reinstall the imaging cartridge and continue printing.

The transfer charger wire may be dirty. Clean the wire as described in Chapter 6.

If the print quality problem persists, replace the imaging cartridge as described in Chapter 6.
