HP — Image-formation troubleshooting

Check the toner cartridge Image-formation defects are often the result of problems with the toner cartridge. Use the following list to verify that the toner cartridge is still operating correctly. Perform all of the following checks before replacing the toner cartridge.  Verify that the toner cartridge has toner. The full toner cartridge weight is approximately 1105 grams; empty weight is approximately 900 grams.  Check the toner cartridge to see if it has been disassembled or refilled.  Verify that the toner cartridge is seated properly in the printer cavity.  Inspect the cartridge for toner leaking through worn seals.

(Manual rotation of the drum can caused internal damage and toner spills can result.)  White areas on the page can indicate the drum has been exposed to light for too long. Note The toner cartridge is rated for 5,000 images at 5 percent coverage. Check the surface of the photosensitive drum in the cartridge to see if it has been damaged or scratched. Touching the drum will contaminate the photosensitive surface and may cause spotting and defects during printing. EconoMode EconoMode creates draft-quality printing by reducing the amount of toner on the printed page by up to 50 percent. Advise the customer to turn EconoMode on or off either from the printer driver or a software application.

CAUTION Hewlett-Packard does not recommend full-time use of EconoMode. If EconoMode is used full-time, it is possible the toner supply will out last the mechanical parts in the toner cartridge. 200 Chapter 7 Troubleshooting C7058-90936
