Toner cartridge 

A new toner cartridge contains enough toner to print up to 12,000 A4 
or Letter-size single-sided pages at about 5% coverage. 

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 EMPTY message. To replace the toner cartridge, 
see Replacing the toner cartridge in this chapter.

TONER LIFE END message

Check printed pages, page counter, and LCD messages routinely. 
When TONER LIFE END is displayed on the LCD, we have two 
conditions as to why this has happened.
First condition: Actual: this is when the ‘Actual’ amount of toner in the 
toner cartridge has been used up.
Second condition: Mechanical: this is when the ‘Mechanical’ 
components of the toner cartridge have physically reached the end 
of their life.
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.
