Toner cartridges 6

Note

• The amount of toner used varies according to what is printed on the page and the print density setting.

• Wait to unpack the toner cartridge until immediately before you put it into the printer.

Toner nearly empty message 6

Check printed pages, page counter, and display messages regularly. If the o indicator starts blinking, the

printer has nearly run out of toner or the toner is not evenly distributed inside the cartridge.

Ready

o n n o

The four o marks (also n, n=blinking o) indicate the Black (K), Yellow (Y), Magenta (M), Cyan (C) toner

cartridges from left to right.

Although you can print up to 300 additional pages (at 5% coverage) after the Toner Low message first

appears, be sure to replace the toner cartridge with a new one before it becomes completely empty. When

this occurs, the o indicator on the LCD will disappear.

Toner Life End message 6

When the following message appears on the LCD, you need to replace the toner cartridge:

Toner Life End

Replace Black(K)

The second line of the LCD indicates which color you need to replace.

Note

• To ensure high quality printing, we recommend that you use only genuine Brother toner cartridges. When

you want to buy toner cartridges, call your dealer or Brother Customer Service.

• We recommend that you clean the printer when you replace the toner cartridge.
