Ribbon Motion Sensor 
Removal Procedure 
1.  Unplug the printer. 
2.  Remove the ribbon cartridge and cleaning roller. 
3.  Remove the 
Main Enclosure (p. 6-8). 
4.  Remove the sensor: 
A.  Insert a screwdriver under the sensor's circuit board and gently
 twist to 
free the sensor from the retaining pin. 
B.  Continue to pull the sensor out of the chassis by grasping the sides of the 
circuit board. 
5.  Disconnect the sensor cable connector from the sensor's circuit board.  
 
Replacement Notes 
•  When replacing the sensor, do not push against the cable connector—the 
solder leads will bend. Push against the corners of the circuit board. 
 
•  Use the sensor display in Diagnostics to verify that the sensor changes state 
as the ribbon supply spindle is rotated.
