ImageWriter II/L Basics - 11
Reset Circuit
This circuit is used when the printer is
turned on to keep the logic in a reset state
until the voltages are up to correct values.
Once the voltages are at the correct level,
reset is released and the logic is allowed to
start functioning from a known state.
Connector CN6
This connector is a LocalTalk option card
connector. This card allows the printer to
communicate on the LocalTalk network so
that multiple users can use the printer.
Clock Crystals
There are two clock crystals on the main
board. The clock X1 for the gate array IC4
runs at 17.2 MHz. The clock X2 for the CPU
runs at 12 MHz.
DIP Switches
The configuration DIP switches are mounted
on the main board and can be changed to
make the printer perform in different
modes, or control printer protocols. The
switch settings affect both the CPU and the
gate array logic.
