Lever Drive Circuit
This printer has two levers to drive the mechanism. The lever motor rotation enables lever A
and lever B to function. This controls the mechanism.
Lever A and lever B are solenoids driven by 24V. Simple drive of lever A and lever B is
performed by an NPN Darlington transistor. LEVER1 and LEVER2 are output signals from the
CPU.
Lever A: Driven by a LOW level of the LEVER1 signal
Lever B: Driven by a LOW level of the LEVER2 signal
