Paper feed motor drive circuit (journal)
When transistor QM2 becomes on in response to the PFJ1 and PFJ2 switching signals from the
CPU, the paper feed motor is activated. The PFJ_HL signal switches the motor between drive
and hold. During hold, Q28 goes off and a current is supplied from the 5 V power supply.
The same circuit is provided for the receipt side.
