Where can one find help with a LaserJet IIIP that is producing an ERROR 52?
A. Early models of the LaserJet IIP/IIIP, Apple Personal Laserwriter, QMS PS410, and other printers with the Canon LX laser engine have a defect in the scanner assembly that causes the scanner speed control IC to overheat and burn out. This is sometimes indicated by the smell of a printed circuit board burning. This error can begin as an intermittent error which can be corrected by pressing Alt-continue (on HP printers), but eventually it cannot be worked-around this way. HP’s web sit suggests taking the printer to HP Authorized Service Center for repair. An upgraded assembly with step-by-step instructions can be purchased from All Laser Service for about $70 U.S. The assembly is buried deep in the center of the printer, and takes about three quarters of an hour to change.
