7-56 Troubleshooting
Note 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
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.
CAUTION 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.
