Installation
To install a Scalable Fonts Kit, proceed as follows:
• Turn off the power, and disconnect the power cord.
• Open up the electronics compartment by removing the eight #T10
Torx screws that hold the left-hand cover.
• Check that there are no jumpers fitted in the right-hand position
on P-100, P-101, and P-102 on the CPU board. Such jumpers
indicate that the printer is fitted with Flash Memory packages,
which excludes the installation of the Scalable Fonts Kit. No
jumpers fitted, or jumpers fitted in the left-hand position, is OK
1 .
• Remove the existing GAL circuit on IC-700 on the CPU board
and replace it with the smallest of the circuits included in the kit.
The small semicircular mark must face upward.
• Fit the EPROM package marked “# 5” in socket IC-104, and the
EPROM package marked “# 6” in socket IC-105.
In both cases, the semicircular mark must face upward.
• Inspect the circuits you have fitted for bent legs. If necessary,
remove the circuit and refit it.
• Put back the left-hand cover, connect the power cord, and turn on
the power.
