Removing the Main Circuit Board

The main circuit board of the printer is equipped with two sockets for memory expansion.
Expansion memory is available in the form of a SIMM.
The following instructions are intended for the technician only.
Notes on Handling the Main Circuit Board and SIMM
Protect the electronics by taking these precautions:
Before touching the main circuit board, touch a water pipe or other large metal object to dis-
charge yourself of static electricity. While doing the work, it is recommended that you wear
an antistatic wrist strap.
Touch the main circuit board and SIMM only by the edges.
Withdrawing the Main Circuit Board from the Printer
Be sure to remove the memory card first if inserted in the printer's memory card slot.
Withdraw the main circuit board completely from the printer as follows:
1.
Turn the printer's power off. Unplug the
printer's power cable and disconnect the
printer from the host computer.
2.
Remove the five screws from the printer's
rear cover.
3.
Pull the main circuit board all the way out of
the printer.
Before pulling the main board out, clean an
area on the table, etc., at the back of the
printer's rear panel. Foreign objects, acci-
dentally sticking to the back of the main
board, can cause serious damage to the
printer.
Install the SIMM as described on the next
