Gray background

Decrease the print density setting. This will decrease the amount of background shading. Access this setting under “Printer properties (driver).”

Change the paper to a lighter basis weight. See “Printer paper specifications.”

Check the printer’s environment; very dry (low humidity) conditions can increase the amount of background shading.

Install a new HP toner cartridge. See “Changing the toner cartridge.”

Toner smear

If toner smears appear on the leading edge of the paper, the paper guides may be dirty. Wipe the paper guides with a dry, lint- free cloth. See “Printer components” or “Cleaning the printer.”

Check the paper type and quality.

Try installing a new HP toner cartridge. See “Changing the toner cartridge.”

Loose toner

Clean the inside of the printer. See “Cleaning the printer.”

Check the paper type and quality. See “Printer paper specifications.”

Try installing a new HP toner cartridge. See “Changing the toner cartridge.”

Vertical repetitive defects

The toner cartridge may be damaged. If a repetitive mark occurs at the same spot on the page, install a new HP toner cartridge. See “Changing the toner cartridge.”

Internal parts may have toner on them. See “Cleaning the printer.” If the defects occur on the back of the page, the problem will likely be corrected after a few more printed pages.
