Computer displays message "missing developer unit" Just the same - Printer is only 11 month old.
Generally this printer can be separate into 4 major part: Printer body, Toner container, Developer unit and Drum unit. The developer unit is the unit where the toner container "mount" on it and it should be removed to allow cleaning task every time the toner container is replaced.
U may get this error message if the developer unit is not install properly after u replace a new toner container. Just lift the developer unit together with the toner container out of the printer and then insert back properly into the machine.

Though "Missing Developer Unit" is displayed, in most cases this problem can be resolved by replacing the toner catridge.
That comment is the solution for in most cases. I don't know how to mark this "solved"
