he error code deals with the scanner unit / scanning lamp. Have you just cleaned the optic's???? Was the problem there before you started to work on it? Dos the scanner lamp turn ON? I the lamp dos not come on, you will need to replace the lamp and the lamp regulator PCB at the same time as a set. Very,very important... They need to be changed as a set. If you have a working parts machine, I would use the parts from the parts copier. Good Luck
