CUTTER SENSOR ADJUSTMENT
This sensor adjustment regulates penetrating ability for the cutter sensor. Penetration
modification is performed via a potentiometer that is part of the cutter assembly. To establish the
penetration level, upper and lower limits must be set. These activities require the use of a
multimeter.
1 Load the printer with media and ribbon as applicable and power on.
2 Connect the multimeter ground probe to the pin identified as SG on the cutter sensor board.
3 Connect the multimeter positive probe to the relative pin on the cutter sensor board.
4 Physically place the media into the cutter assembly so the sensor is facing the printable
media and record the multimeter reading.
5 Move the media so that the sensor is facing its reference mark and record the multimeter
reading.
6 Adjust the relative potentiometer to the required multimeter reading.
7 Regard the multimeter display to determine the difference or upper limit.
8 Repeat steps 6 through 9 until the required difference is achieved.
9 Begin normal printing to ensure proper adjustment.
NOTE: Refer to the CUTTER REFERENCE CHART table below for the
assigned connector pins, the potentiometer to be adjusted, and the desired
multimeter voltage values. The sensor switch must be in the proper position
when setting the cutter sensor’s penetrating sensitivity.
NOTE: For tutorial purposes; the HO pin is for hole sensing, the IM pin is for
eye-mark sensing, and the SG pin represents signal ground.
