6-22  Removal and Replacement 
Card Hopper Empty Sensor 
The Input Hopper Empty Option has a bracket that clips onto the Card Tray. The 
sensor fits into the bracket and plugs into the J40 connector labeled Spare.  
  Even though this sensor displays on the Diagnostics Sensor screen, it is 
used only by the printer driver API and is not reported to the driver; it will 
have no affect on the printer or error messages from the driver. The sensor 
can be utilized only after a programmer has done custom development to 
incorporate it. 
Removal Procedure 
1.  Unplug the printer. 
2.  Remove the 
Main Enclosure (p. 6-8). 
3.  Unplug the Hopper Empty sensor from the J40 connector labeled Spare. The 
plug is located below the CAM Motor. 
 
4.  Pull the wire free from the printer. 
5.  Unclip the sensor bracket from the Card Input Hopper. 
 
Replacement Notes
