5 Rewind full sensor (Transmissive sensor)
This sensor detects excessive winding when winding backing paper or label onto the take-
up spool. It is positioned 195.3 mm (Tr side) and 150.9 mm (LED side) from the platen, and
the detection point is 92.5 mm from the main frame. Excessive winding is detected when
backing paper blocks the light from the LED.
6 Slit sensor (Transmissive sensor)
This sensor detects the rotation count of the ribbon shaft and the ribbon motors. The ribbon
motors toque works to take up slack in the ribbon and is dependent on the detected count.
The slit sensor is a photo coupler combining an LED and a transistor.
7 Cutter home position switch (micro switch)
A cam positioned at the end of the cutter motor arm turns the micro switch on/off in
accordance with the cycle of the cutter motion (one rotation). The micro switch status
indicates if the cutter is in the home position.
For details, please refer to the Maintenance Manual section 4.1 Cutter Drive.
