Monitoring drum usage

You should check the indicator light on the drum replacement cartridge each time you change the toner cartridge. This indicator helps you monitor drum usage, as described on page 6-11. The indicator light lets you know in advance of the display panel when the drum unit should be changed.

CAUTION: If you regularly print high density graphics (more than 20 percent page density), you need to replace the drum unit more frequently. You must keep track of the number of toner cartridges you have used, and replace the drum unit and drum replacement cartridge at the same time you install the eighth toner cartridge. Do not wait for the CHANGE DRUM message to appear on the control panel. Overuse of the drum unit results in a reduction of print quality and increased maintenance requirements.
