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.
