If a finisher is installed:
•
The AC jumper should go from the HCIT to the finisher. The finisher AC power cord should attach to the AC
voltage source. The base printer power cord should plug into the AC output connector on the HCIT.
•
If a finisher is not installed:
The printer power cord plugs into the HCIT AC outlet and the power cord from the HCIT plugs into the AC
voltage source.
Note:
Make sure the electrical outlet is working properly and all power cords are plugged in correctly. Make sure
the slide switch on the LVPS is toward the right.
The system board status LED can be observed by removing the rear cover. The LED is mounted on the HCIT
