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
Initiate a Self Test. As the test begins, listen for the sound of the
scanner motor. If the motor cannot be heard, perform the
following in the order given:
1 Check the Laser/Scanner and the Power Supply cables.
Replace if necessary.
2 Replace the Laser/Scanner Assembly.
