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 three 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, accidentally sticking to the
back of the main board, can cause seri-
ous damage to the printer.
