CHANGING THE TONER CARTRIDGE
When the toner is running low, *** TONER LOW is displayed in the
control panel (*** is the color name). If printing continues without
replacing the toner cartridge,
CHANGE *** TONER is displayed and
printing is cancelled.
Depending on the operating environment, print may become faint
before this message is displayed. If this happens, remove the toner
cartridge and check whether it is empty; if so, the toner cartridge
needs to be replaced.
Cartridge life is approximately 15,000 letter-size pages at 5% print
density. The first toner cartridge installed in a new image drum needs
to be replaced after less than this amount because the toner
cartridge has to fill a new image drum.
1. Switch off the printer and open the top cover.
