Hi,

I jsut followed the instruccion with a Lexmark X544 but i cant see the "Reset Maintenance Count". I could get de CONFIG MENU by holding the /check) and (right arrow). I move in the menu but none of the lines is anything related to "Reset Maintenance Count"

In output between rollers you have a plastic parts wich moves. They are the output bin sensor. Maybe are stuck, see if moves.

You will get this message if the imaging unit needs replacement. Please visit the link below to view the video and the instructions on how go about the replacement.

i have had a customer with the same problem we thought taking the colour cartridge out would set the printer to black only not even setting the settings in the printer menu worked i later found out from lexmark that the printer will not work unless both carts are in the cradle and contain ink. ... clever way to get you to buy a new cart right away

sorry
take care
