I keep getting the error message "Authenticate Err (Authentication error)".

No Waste Toner

No Belt Unit

Size mismatch

Toner Low

Clear the message "Awaiting Redial"

Drums End Soon/ Drum End Soon(X)

Drum Error (Drum!)

Why does the message "No Response/Busy" appear on my Transmission Verification Report?

I still receive the error message "Replace Drums", "Replace Drum(X)", "Drums End Soon", or "Drum End Soon(X)" after I replace the drum unit with a new one.

No Paper

Jam Inside

When I send a fax from the machine, an error "not register." or "not registered." is displayed.

Document Jam

Jam Rear

Jam Tray

Out of Memory

Belt End Soon

WT Box End Soon

What does "COMM.ERROR" on the LCD display mean?
