• Remove and re-insert the cartridge.
• Check the drum (roller Green or blue) for defects, being careful not to touch this part.
• Clean the drum with a dry lint-free cloth.
• Clean the contacts on the cartridge.
• Print 5–10 pages to remove potential foreign material under the wiper blade.
• If the problem persists, install a new cartridge.

Resolution 1

• If the whole page is light, the print density adjustment may be too low or EconoMode might be turned on.
• Adjust the print density and disable EconoMode in the printer driver.
• At the product control panel, select the CONFIGURE DEVICE menu, then select the PRINT QUALITY submenu (EconoMode is off by default).
• In the embedded Web server, open the Settings tab and select Configure Device, then navigate to the Print Quality submenu.
• In the HP Printer Utility for Macintosh, click Configuration Settings, then click Economode & Toner Density.
• In the Windows PCL printer driver, open the Paper/Quality tab and select the EconoMode option.

Resolution 2

• If the print quality is poor, remove the toner cartridge from the printer and gently rock the cartridge from side to side.
• This movement helps distribute the toner evenly within the cartridge.
• After rocking the cartridge 5–6 times, re-insert the cartridge into the printer and print a test page.

• Print 15–20 pages and see if the problem persists.
