Cutter home position switch (micro switch)
A cam positioned at the right side of the cutter turns the micro switch on/off in accordance with the
cycle of the cutter motion (half rotation). The micro switch status indicates if the cutter is in the home
position.
5
Cutter cover open switch (micro switch)
The cutter cover open switch is located on the lower front part of the cutter unit.
This switch detects that the cutter cover is opened when the tab of the cutter cover is released from
the actuator arm and the micro switch turns OFF.
3
Slit sensor (Transmissive sensor)
This sensor detects the rotation count of the ribbon slit gear and the ribbon motors. The ribbon
motors torque 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.
The slit sensor (feed) also detects a ribbon end. When the ribbon has been used up, the ribbon
slit gear stops and the slit sensor does not turn on and off.
