Solenoid Drive Circuit

Main PBA
IC37
Engine-CPU
The solenoid drive circuit consists of the Engine-CPU (IC37) as the central component. It drives the
paper pickup solenoid connected to CN14 and controls the paper feed timing for the recording paper
placed in the recording paper tray and bypass tray.
The Engine-CPU causes the MP_PICK_UP_SLX signal to go HIGH to turn on IC60. This allows the
paper pickup solenoid to be driven to transmit power to the pickup roller for feeding the recording paper.
