Printer Hangs With The Xerox Logo Displayed, Or Reboots - Xerox Phaser 7100 Service Manual

Error Troubleshooting

Printer Hangs with the Xerox Logo Displayed, or Reboots

1. Verify that the printer is plugged directly into a wall outlet and that the circuit is capable of
meeting the power specifications for the printer (voltage within the specified range and less than
a 10% drop in voltage when printing). The printer will not perform reliably when plugged into a
surge protector, power strip or an un-interruptible power supply.
2. Power Off the printer, disconnect the network or USB cable and then power the printer back On. If
the printer comes to Ready, print an internal page from the Control Panel, then make a print from
a laptop connected directly to the printer. If both of the print jobs are successful, the problem is a
network issue and normal network troubleshooting procedures should be used. If the printer does
not come to Ready, try pressing the Cancel button to clear any jobs from the queue that could be
causing the printer to hang. The Cancel button may have to be pressed multiple times to clear out
all jobs. Then try to print internal pages and from a laptop again.
3. Initialize NVRAM.

7. Replace individually, in order of priority:
– Image Processor EEPROM PWB
– Image Processor PWB
8. Corrupt NVRAM on the MCU PWB can cause the printer to continually reboot. As a last step, try
