Main board
Tools required
Magnetic screwdriver
T-15 TORX tip
Caution
After replacing the main board, before turning on the printer,
always make sure that the head tilt cam gear is latched by the head
tilt solenoid and that the head tilt cam gear is disengaged (via its
missing teeth) to the drive gear.
1.
Power down the printer. Leave the power cord plugged in to provide
a ground path for static discharges. Remove the interface cables.
2.
Loosen the two rear panel securing screws.
3.
Slide out the image processor board.
Reverse these steps to reinstall the main board. If you are replacing the main
board, swap the socketed NVRAM chip and printer ID chip with the new board
so the printer's settings and Ethernet address are retained. Also swap the
network card, ROM SIMM and the RAM SIMM as described in the following
procedures.
