Note

CAUTION

Toner Cartridges are rated for 6,000 or 10,000 images at 5% coverage (depending on the model). It is possible to wear out the gears and the cartridge seals before TONER LOW is displayed if the number of images exceeds 6,000 or 10,000 (depending on the model). See “EconoMode” below.

●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.

●White areas on the page may indicate that the Drum has been exposed to light for too long. If white areas appear, stop the printer and wait a few minutes This should eliminate most defective images. If not, place the Toner Cartridge in a dark environment for several days. This can restore some life to the Drum.

EconoMode creates draft-quality printing by reducing the amount of Toner on the printed page by up to 50%. Advise the customer to turn EconoMode on or off from the printer driver or software application, since those settings override the Control Panel settings. EconoMode settings can also be accessed from the Print Quality Menu.

HP does not recommend full-time use of EconoMode. If EconoMode is used full-time, it is possible that the Toner supply will outlast the mechanical parts in the Toner Cartridge.
