REPLACE
THE
AR-P15
MOTHERBOARD
Wear an ESD grounding strap and follow standard ESD (electrostatic discharge)
precautions while performing this procedure.
1.
Shut down the copier and remove the AR-P15 from the copier (according to the
installation instructions, not provided in this guide).
2.
Remove and set aside the 6 screws that attach the motherboard to the chassis.
3.
Remove and set aside the 2 screws that attach the parallel port connector to the chassis.
4.
Remove the motherboard from the chassis.
5.
Remove the following standard components from the motherboard:
• DIMM in J49 (See page 7)
6.
Remove any of the following optional components from the motherboard:
• Optional DIMM in J48
• Optional HDD, if present
• Optional key chip in U800, if present (see Figure C on page 5 for location)
Instructions for removing optional components are not provided in this guide.
7.
Unpack the new motherboard.
8.
Install the standard components you removed earlier onto the new motherboard.
To reinstall memory, see page 7.
9.
Install any optional components you removed earlier onto the new motherboard.
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.)

Install the new motherboard into the chassis using the 8 screws you removed earlier:
• 6 screws attach the motherboard to the chassis
• 2 screws attach the parallel port connector to the chassis.
