Service checks	63
1. Power to the LVPS/HVPS	63
2. Power from the LVPS/HVPS to the controller card	63
3. Cables are plugged in correctly, especially for the operator panel. The printer will not power-up without a functioning operator panel.	63
4. The controller card assembly.	63
5. The operator panel. See “Operator panel service check” on page 3-43.	63
1. Turn the printer off.	63
2. Disconnect the LVPS/HVPS cable from the controller card at J19.	63
3. Turn the printer on.	63
4. Verify +24 V dc on positions 8 and 9 of the cable connector.	63
5. If voltage is correct, check the continuity in the other conductors of the cable. If the cable is good, check the connectors to the controller board.	63
6. Verify that pins 7 and 12 on both the cable and the card connector are grounded.	63
7. If grounds are not correct on the cable, but the cable posses continuity otherwise, check the LVPS/HVPS.	63
8. If the grounds are not correct on the controller card, replace the controller card. (Check with one probe on the connector pin and the other on the card’s ground plane found at each screw head.)	63
