Checking the Toner Level
The user can find out how much toner is left in the toner cartridge
by printing a configuration page (see page 134). The toner level is
represented by the HP TonerGauge graphic on the configuration
page. It shows approximately how much toner is left in the toner
cartridge.
Note
After replacing a toner cartridge this value might become inaccurate
if a user fails to select
YES
when the
NEW TONER CARTRIDGE=NO
message is displayed on the control panel.
Resetting the HP TonerGauge
After a new toner cartridge is installed, the user must reset the
HP TonerGauge from the control panel. When the top cover is
closed after installing the new toner cartridge, the
NEW TONER
CARTRIDGE=NO
message is displayed on the control panel for
approximately 30 seconds. To reset the HP TonerGauge:
1
Press
[- Value +]
until
YES
appears.
2
Press
[Select]
to save the selection.
3
Press
[Go]
to exit the menu.
Note
If the
NEW TONER CARTRIDGE=NO
message is no longer displayed
on the control panel when you replace an empty or low toner
cartridge, press
[Menu]
repeatedly until
CONFIGURATION MENU
appears. Press
[Item]
repeatedly until
NEW TONER CARTRIDGE=NO
appears, then complete steps 1 through 3 above.
