KX-P7100
4.4.14. Solenoids Control Circuit
This printer has three solenoids: pickup solenoid, registration solenoid and a switchback solenoid.
4.4.14.1. The Pickup Control Solenoid Drive Circuit
The pickup solenoid is used for picking up the media from the media tray. The CPU IC11 outputs high level PUCTL signal from
pin41 to the transistor Q20. The transistor Q20 and Q23 are turned on and supplies +24V power to the solenoid.
4.4.14.2. The Registration Solenoid Driver Circuit
The registration solenoid is used for controlling Registration Roller rotation. The CPU IC11 outputs high level REGCTL signal from
pin42 to the transistor Q21. The transistor Q21 and Q24 are turned on and supplies +24V power to the solenoid.
