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

I still receive the error message "Replace Drum", "Drum End Soon", "Drum Near End", or "Drum Stop" 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.

When scanning a document to be copied, the LCD shows "OUT OF MEMORY". What should I do?

How can I clear the "Scanner Locked" error message?
