TONER LOW Message
(Appears at intervals)
If the LCD shows TONER LOW, the toner cartridge has nearly run out of toner. Purchase a new toner
cartridge and have it ready before you get a TONER LIFE END message. To replace the toner cartridge,
see Replacing the toner cartridge on page 5-3.
TONER LIFE END message
Check printed pages, page counter, and LCD messages routinely. When TONER LIFE END is displayed
on the LCD, the printer has run out of toner or the toner is not evenly distributed inside the cartridge.
For both conditions the printer will stop printing, until a new toner cartridge has been put into the printer.
TONER LIFE END can only be cleared, by putting a new toner cartridge into the drum unit.
■Toner consumption varies according to the image coverage on the page and the print density
setting.
■The greater the image coverage, the greater the toner consumption.
■If you change the print density setting for lighter or darker printing, toner consumption varies
accordingly.
■Wait to unpack the toner cartridge until immediately before you install it in the printer.
