Replacing the Toner Bottle

The toner bottle is designed to last approximately 5000 printed pages under the condition of 5% coverage on A4 paper or last about one year after unpacking. The first toner bottle may print slightly fewer pages.

Replace the toner bottle when the message display indicates TONER LOW or TONER EMPTY or when printing becomes lighter than you find satisfactory. After the toner low condition occurs, you can only print about 20 more pages. Under the toner empty condition (no toner), the printer will not work.
