6.10 ADJUSTING CUTTER SENSORS (Cont’d)
To calibrate the Gap/ Center hole sensor level with the potentiometer
NOTE:
Measure the sensor level directly in the
Maintenance
mode only. This is because the sensor
protection (measurement to prolong operating life) is enabled in the
ONLINE
mode.
5.
The potentiometer of cutter unit is used for adjusting the cutter sensor. Set the multimeter to direct-current
voltage mode. Connect
[+]
probe to
HO
check pin on the cutter sensor PCB (upper) and
[ - ]
probe to
SG
check pin.
6.
To adjust low level (Gap or Center hole/without tag), ensure the label liner is set (or no tag is loaded) onto
the cutter sensor and then use the microdriver to adjust the
VR1
potentiometer until the sensor level shows
+0.5V
or below on the multimeter.
7.
To adjust high level (label/ tag), load the label (or tag) to the
Gap/ Center hole sensor.
8.
Use the microdriver to adjust the
VR1
potentiometer until the sensor level is within the range of more than
or same as
+2.0V
and less than or same as
+5.0V
.
9.
If you are having difficulty adjusting the sensor properly, clean the sensor and check the connector connec-
tion. If the problem persists, replace the sensor.
10.
Turn off the power and install the cutter unit.
Table of normal performance values:
Low level (without media/ tag hole area): +0.5V or below
High level (with label/ tag): +2.0V >= tag area <= +5.0V
