Preliminary on-site checkout
T
O CHECK INTERNAL CONNECTIONS
1. Before you touch any parts inside the copier, wear an ESD grounding strap and follow
standard ESD (electrostatic discharge) precautions.
2. Inspect internal ribbon cables, if any, to see if they are intact.
Faulty ribbon cables are easily overlooked. Check the contact point between the optional
HDD cable and the HDD for separation. Make sure the HDD cable is locked into place
in the connector at J207. If a ribbon cable is suspect, substitute it with a tested cable. The
cable is keyed to fit the AR-P15 connector in only one way (the non-gray line on the
ribbon cable to Pin 1 on the AR-P15 board silkscreen).
3. Make sure that any AR-P15 cables, DIMMs, or other socketed components are properly
aligned and well seated on their connectors.
• Check the AR-P15 motherboard connection to the copier. This connection is for the
printer interface and the Control Panel interface and for receiving power from the
copier power supply.
• Check the connection for each DIMM installed (one if standard, two if upgraded). See
page 7.
• Inspect for bent or broken pins on the optional key chip. These pins are delicate. If
bent, carefully straighten them with a pair of needlenose pliers. Carefully align the 8
pins of the chip with the socket before you insert the chip. Also note that the PS key
chip is not the same as the HDD key chip. (Instructions for installing optional
components are not provided in this guide.)
4. After verifying connections, if one or more AR-P15 components is still not getting
power, check the copier power supply (see copier documentation).
