3.
Before you touch any components inside the Print Controller X4(AR-PE1), attach a
grounding strap to your wrist and discharge any static electricity on your body by
touching the metal cover of the Print Controller X4(AR-PE1).
4.
Inspect the inside of the Print Controller X4(AR-PE1). For details, see “Checking
Print Controller X4(AR-PE1) internal connections” on page 4-8.

shows an exploded view of the system components.
• Look for obviously loose boards and reseat each board securely in its connector on the
motherboard.
• Look for cables that are obviously loose. Reseat each connector firmly.
• Make sure each connector is properly aligned with its mating connector. If the pins are
offset from each other, the board affected will not function properly.
