Toner cartridge replacement
The toner used in this printer is a very fine dry powder. It is 
contained in four cartridges: one each for cyan, magenta, 
yellow and black.
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 by placing it 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.
     
Before changing the toner cartridge, switch off the printer and 
allow the fuser to cool for about 10 minutes before opening the 
cover.
1.
Press the cover release and open the printer’s top cover fully. 
CAUTION!
To avoid toner wastage and possible toner sensor 
errors, do not change the- toner cartridge(s) until 
“TONER EMPTY” is displayed through the Status 
Monitor.
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.
