REPLACEMENT
Only use genuine original consumables to ensure the best quality and
performance from your hardware. Non original products may adversely affect
your printer's performance and invalidate your warranty.
The toner used in this printer is a very fine dry powder contained in the EP 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.
Press the cover release and open the printer’s top cover fully.
CAUTION!
Static sensitive devices, handle with care.
NOTE
When the LCD display indicates EP TONER LOW, or if print appears faded, first
open the top cover and try tapping the cartridge a few times to evenly
distribute the toner powder. This will enable you to obtain the best “yield” from
your EP toner cartridge.
WARNING!
>
Never expose an EP toner cartridge to an open flame. It can
cause an explosion and you can be burned.
>
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 will be hot. This area
is clearly labelled. Do not touch.
