Error Troubleshooting
Xerox Internal Use Only Phaser 7100 Service Manual 2-413
Image Processor (I/P) PWB LEDs
Assessment on the condition of the parts and the condition of the I/P PWB can be done based on the
On/ Off states of the 8 LED’s on the I/P PWB. To check the condition of an error where no Error Code is
displayed, check the LED display on the I/P PWB.
As the device that can be connected differs depending on the board, it does not always necessarily
mean that diagnostic is possible. In the following table, items that are installed as features are marked
with “O”.
Procedure
1. Turn Off the printer.
2. Unplug the power cord from the outlet.
3. Remove the Blind Board of the I/P PWB.
4. Plug in the power plug and turn On the power switch.
