When To Replace The Image Drum - Oki B4400 User Manual

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.
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.
Switch off the printer and allow the fuser to cool for about
10 minutes before opening the top cover.

cartridge towards the front of the printer to close the
cartridge then remove the used toner cartridge.

containing the new toner cartridge to install the new
cartridge.

cleaner that came with the new toner cartridge or soft
tissue.
