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.
