C ONSUMABLES AND MAINTENANCE
This section deals with the replacement of the toner cartridge and image drum and general
maintenance.
W HEN TO REPLACE THE TONER CARTRIDGE
When the toner is running low, TONER LOW is displayed in the operator panel LCD. After
Toner Low displays, the printer will print about 100 more pages then display Toner Empty
and stop printing. Printing will resume after a new toner cartridge has been installed.
R EPLACING THE TONER CARTRIDGE
It is recommended that you clean the LED array at the same time as you change the toner
cartridge.
The toner used in this printer is a very fine dry powder contained in the toner cartridge.
Have a sheet of paper handy so that you have somewhere to place the used cartridge while
you install the new one.
Dispose of the old cartridge responsibly, inside the pack that the new one came in. Follow
any regulations, recommendations, etc., which may be in force concerning waste recycling.
If you do spill any toner powder, lightly brush it off. If this is not enough, use a cool, damp
cloth to remove any residue. Do not use hot water, and never use solvents of any kind.
They will make stains permanent.
1. Switch off the printer and allow the fuser to cool for about 10 minutes before
opening the top cover.
2. Press the top cover release button and open the printer’s top cover fully.
WARNING!
> Never expose a toner cartridge to an open flame. It can cause
an explosion and you can be burned.
> Be sure to switch off and unplug the machine before accessing
the interior of a machine for cleaning, maintenance or fault
clearance. Access to a live machine’s interior can cause electric
shock.
WARNING!
If you inhale any toner or get it in your eyes, drink a little water or
bathe your eyes liberally in cold water. Seek medical attention
immediately.
WARNING!
If the printer has been powered on, the fuser may be hot. This area
is clearly labelled. Do not touch.
