    2.2.2 Thermal printing mechanism The thermal printing mechanism in the printer consists of the thermal recording head, platen, anti- curl system (ACS) plate, and paper compartment cover. The heat-sensitive recording paper is routed between the paper guide bar and ACS plate to the recording head which prints onto the paper pressed by the platen according to image signals issued from the main PCB.

  • Page 14: Sensors

    2.2.3 Sensors This machine has three sensors--PE/cover sensor (photosensor), thermistor in the thermal recording head, and left-hand CIS unit acting as a home position detector of the copyboard screen.
