6.5 Maintaining the toner cartridge

Toner cartridge storage
To get the most from the toner cartridge, keep the following guidelines in mind:
• Do not remove the toner cartridge from its package until ready for use.
• Do not refill the toner cartridge. The printer warranty does not cover damage caused by using a refilled cartridge.
• Store toner cartridge in the same environment as the printer.
• To prevent damage to the toner cartridge, do not expose it to light for more than a few minute.
Expected cartridge life
The life of the toner cartridge depends on the amount of toner that print jobs require. When printing text at ISO 19752
5% coverage, a new toner cartridge lasts an average of either 20,000 or 10,000 pages. (The original toner cartridge sup-
plied with the printer lasts an average of 10,000 pages.) The actual number may also be different depending on the print
density of the pages you print on, and the number of pages may be affected by operating environment, printing interval,
media type, and media size. If you print a lot of graphics, you may need to change the cartridge more often.
Saving toner
To save toner, press Toner Save on the control panel. The button backlight turns on.
Using this feature extends the life of the toner cartridge and reduce your cost per page, but it also reduces print quality.
6.5.1 Checking the remaining toner
You can check the level of toner left in the cartridge.
If you are having print quality problems, this can help you determine if the problem is caused by low toner.
Following the key formation at the panel, note the toner remaining level on the cartridge information after taking out the
configuration sheet. In other way to check, follow the TECH mode and out put the cartridge information.
The display shows the percentage of the remaining toner.
