Printer Inoperable After Power Switch Is On - Xerox Phaser 6250 Service Manual

Printer Inoperable after Power Switch is On

No mechanical initialization observed after the Power Switch is turned On. One
possible cause of this condition is the protection circuitry on the LVPS has detected
an overload condition and temporarily stopped all output. This protective shutdown
lasts no more than 5 minutes following removal of the overload.
Initial Actions
Turn off the printer's Power Switch and remove the Power Cord.
Remove the Image Processor board (page 8-110).
Wait 5 minutes before restoring power to allow the protection circuitry to reset.
