POST (Power-On Self Test)
Note:
The printer should complete POST in approximately 45 seconds.
If the printer fails to display lights or activate the drive motor, fuser, or fan, then check the
following order:
1. Power to the LVPS/HVPS
2. Power from the LVPS/HVPS to the engine board.
3. Cables are plugged in correctly, especially for the operator panel. The printer will not
power-up without a functioning operator panel.
4. The operator panel. See
“Operator panel service check” on page 2-43
24 V dc input from the LVPS/HVPS.
1. Turn the printer off.
2. Disconnect the LVPS/HVPS cable from the engine board at J502.
3. Turn the printer on.
4. 24 V dc on positions 6, 17, and 19 of the cable connector (LVPS/HVPS).
5. If voltage is correct, then check the continuity in the other conductors of the cable. If the
cable is good, then turn the printer off, and check the connectors to the controller board.
6. Verify that pins 10, 12, 14, 16, and 18 on both the cable and the card connector are
grounded.
7. If grounds are not correct on the cable, but the cable passes continuity otherwise, then
check the LVPS/HVPS.
8. If the grounds are not correct on the engine board, then replace the engine board.
(Check with one probe on the connector pin and the other on the card’s ground plane
found at each screw head.)
Engine board voltage outputs
Turn the printer off, and plug the LVPS/HVPS cable into J502 of the engine board. See the
wiring diagram at the end of the manual which identifies the output voltages and grounds
for a good engine board.
Turn the printer off before plugging or unplugging any connectors.
LVPS/HVPS
Verify main power to engine board
With the printer off, unplug the LPS/HVPS cable at J502 on the controller board. Verify
grounds on pins 10, 12, 14, 16 and 18 for both the cable and the engine board. If any of
these grounds are incorrect, then check the cable for continuity. If the cable fails continuity,
then call the next level of support.
Turn the printer on with the cable still unplugged, and verify the following on the cable
(engine board will not be powered):
If any of the voltages are incorrect, then replace the LVPS/HVPS. See
.
