Basics Sub PCB Board - 12
Sub PCB Board
The sub PCB board acts as an
interface board. The
interface cable from the host
CPU is plugged into the
connector CNS1 on this
board. The signals from the
host CPU pass through the
sub PCB board on their way
to the main board. If a cut-
sheet feeder is attached to
the printer, the signals
pass through the sub PCB
board through CNS2, which
controls the actions of the
feeder.
