4.4.10. Solenoids Control Circuit
This printer has three solenoids: pickup solenoid, registration solenoid and a switchback solenoid.
4.4.10.1. The Pickup Control Solenoid Drive Circuit
The pickup solenoid is used for picking up the media from the media tray. The CPU IC004 outputs high level PUCTL signal from
pin41 to the transistor Q023. The transistor Q023 and Q013 are turned on and supplies +24V power to the solenoid.
4.4.10.2. The Registration Solenoid Driver Circuit
The registration solenoid is used for controlling Registration Roller rotation. The CPU IC004 outputs high level REGCTL signal from
pin42 to the transistor Q024. The transistor Q024 and Q014 are turned on and supplies +24V power to thesolenoid.
