Chapter 22-94Cutter right position sensorThis is a photo-interrupter-type sensor. This sensor detects that the cutter is at the right end.F-2-100Feed roller HP sensorThe feed roller HP sensor detects the change from the white portion (unshielded sensor light) to black portion (shielded sensor light) of the encoder film on the feedroller, thus setting the home position for feed roller eccentricity compensation.Feed roller encoder sensorThe feed roller encoder sensor detects the slits on the encoder film of the feed roller during feed motor rotation, thus detecting the amount of rotation of the feedroller (media feed amount).F-2-101Roll media sensorThis is a photo-interrupter-type sensor. When media is loaded, the the sensor arm blocks the sensor light, thus detecting the media.Roll cam sensorThis is a photo-interrupter-type sensor. When the roll cam blocks the sensor light, lowering of the transport roller (contact with the roller) is detected.Feed roller HP sensorFeed roller encoder sensorRoll cam sensorRoll media sensor
