When the cleaning solenoid [A] is energized, the solenoid arm lowers the
pressure arm [B]. This frees the pressure release lever [C] and the blade
spring [D] applies pressure to the cleaning blade.
To ensure cleaning blade operation, +38 V is applied to the solenoid for 0.3
seconds as initial activation, then +24 V is applied.
