Replace the drum unit.

Replace the toner cartridge

What is the difference between the toner cartridge and the drum unit?

"Clean Corona Wire" message continues to appear on the PC screen, even though I have cleaned the corona wire of the drum unit.

I just replaced the toner cartridge and the LCD continues to display the message "Toner Low" / "Replace Toner" / "Toner Life End" or the Toner LED is still on or flashing.

The Drum LED is still on or flashing after I replace the drum unit with a new one.

I don't think I got the full yield from my high-yield toner cartridge but the message "Toner Life End" or "Replace Toner" is displayed on the machine or the LED is on or flashing.

I recently installed the starter or a new toner cartridge and I don't think I got the full yield from the toner.

Can I buy any MICR toner?

What are the expected yields of the consumables?
