Owner`s manual

The materials you will need to supply are:
Flat head screwdriver
IC DIP extractor or a pair of curved needle-nose pliers
1.
IMPORTANT:
Remove power from the printer by positioning
the on/off switch to the "0" (off) position and removing the
AC plug from the AC outlet.
2. Disconnect the network cable from the print server and
remove the unit from the printer by first loosening the 2
thumbscrews located on the front panel with the flat head
screwdriver. Next, remove the unit from the MIO slot by
pulling on the thumbscrew posts.
3. Refer to
Appendix E.2
for the mechanical layout. With the
front of the unit facing towards you, locate socket
U5
. The
existing EPROM will have a label on it with the model
number and firmware revision indicated.
4. Remove the existing EPROM from the socket with IC
extractor or needle-nose pliers. Gradually loosen each side
of the chip, alternating pliers from side to side, so as not to
bend chip pins. Pull loosened EPROM all the way out.
5. Install the new EPROM into the socket. The EPROM is
notched; the notch on the EPROM will point up with the
board oriented as shown in
Appendix E.2
. When installing
the new chips, be careful not to bend any of the pins. Also
make sure all pins fit their sockets.
NOTE:
If the upgrade EPROM has fewer pins than holes on
socket
U5
, the EPROM should be installed so that there are
2 empty rows of holes closest to the notch on socket
U5
.
6. Replace the cover; the upgrade is now complete.
