Full Cutter Motor Driver Circuit and Media Feed Motor Driver Circuit
(1) Full Cutter motor driver circuit
This circuit drives the DC motor to cut a medium as described in subsection “2.1.4 Automatic
Tape Full Cutter Mechanism”. When the CPU receives cut request from the “Cut button
ON/OFF circuit (refer to 2.3.2(3))”, it confirms that the top cover ASSY is closed, and turns
VHON (81 pin) high. Then the CPU controls C_DCF (37 pin) and C_DCR (38 pin) to driver
the cutter motor.
(2) Media feed motor driver circuit
When the CPU receives feed request from the “Feed button ON/OFF circuit (refer to
2.3.2(2))”, it confirms that the top cover ASSY is closed, and turns VHON (81 pin) high.
Then the CPU controls SIN 1 (44 pin) through SIN 6 (49 pin) to driver the media feed motor.
