52 ERROR Scanner Malfunction

The scanner motor is a flat, brushless, DC motor. Motor operation is completely controlled by the DC Controller.

The scanner motor is enabled when the printer is powered-up (during the printer’s power-on self test), or whenever the PRINT command is received by the Formatter PCA. The scanner motor makes a distinctive sound when starting. The sound can be described as a “variable pitch whirring” sound. Listen for the sound of the scanner motor when troubleshooting the 52 ERROR.

Laser/Scanner Assembly Functional Checks

1 Check the Laser/Scanner and the Power Supply cables. Replace if necessary.
