GP 24 Sensor / Actuator
To control the printer engine, some sensors and actuators are necessary:
• COVER: this signal enables the CPU to monitor the status of the cover. If 0, the cover is
open the power supply to the PSU and the fuser are switched off. If 1, the cover is closed
and the PSU and the fuser are normally supplied.
• nFAN and nFAN_HA enable the CPU to drive the fan at full or half speed. When both are
inactive, the fan is switched off. The drawn current is 70mA at full speed and 35mA at half
speed.
• PICKUP: Drive the solenoid to pickup paper. This signal is activated during 300ms to
release the roll that picks up the paper. While activated, the current is 200mA and sup-
plied by the 24V.
• PAPER EMPTY* : Detects if there is some paper left in the cassette.
• REGISTRATION*: Detects that the paper is correctly picked up from the cassette and
enters the paper way.
• PAPER EXIT*: Detects that the paper is going out of the machine
