4-14 PRINTER CIRCUIT
Printer Motor
The printer motor is activated using the signal P00 from the CPU.
This signal is normally Low, and goes High to cause the motor to run.
Printer Magnets
The signal P01 from the CPU is the input for the printer magnets.
These normally low signals drop high with a print signal
.
Timing Signal
The printer generates, through the use of a mechanical switch assembly, a timing signal that is
returned to the CPU.
The CPU uses this signal from the printer as the basic for timing the printer magnet signals, the
motor drive and feed.
