Power Connector Pinout - Xerox 1235DT - Phaser Color Solid Ink Printer Service Manual

DC Output: With the DMM set to measure DC voltages, measure the voltages at
the POWER connector on the bottom of the print engine controller board for
+3.3VDC, +5 VDC, +12 VDC and +32 VDC. (You must remove the right side
cover and right shield plate to access the engine controller board.)
If the voltages are not correct, inspect the wiring harness connecting the POWER
connector of the engine controller board to the CN1 connector of the low-voltage
power supply. If the harness is undamaged, replace the power supply.

If DC voltages are not being output by the power supply, proceed to the next step,
"Inspecting the low-voltage power supply fuse" on page 36.
If the +5 and +32 VDC voltages measure correctly, but the printer does not operate
correctly, then proceed to the topic, "Safety interlocks" on page 36.
