Installing additional memory
To install a memory chip set or a memory expansion board you
need a cross-head screwdriver and a chip puller or a flat-head
screwdriver. If you have questions about installing the chip
set or the board, contact your dealer for assistance.
WARNING: High voltages are present inside the printer
when the power is on. Do not attempt to remove the
controller board unless the printer is turned off and the
power cord is unplugged. Also, try not to touch the
contacts on the printer’s circuit board because many of
the components can be destroyed by the static electricity
in your body.
The rest of this chapter describes the procedures for installing a
memory chip set and/or the OK expansion board.
Removing the controller board
