At the start of a print job, the solenoid turns off. The stack height detection lever
comes down, to detect the current stack level.
When a sheet of paper is being fed out, the solenoid turns on and the lever goes
back up to home position (inside the unit).
After paper has been fed out, the solenoid turns on again, and the lever detects the
level of the stack.
