Chapter 10 Label-Taken Sensor
Adjust the sensitivity of the label-taken sensor by means of the
potentiometer WR51 (marked “LTS”) on the CPU board:
• Start up UBI Fingerprint and run the program described in
chapter 10.2. Leave the label in the outfeed slot to create a label-
not-taken condition.
• The printer should start to beep continuously. If not, turn the
potentiometer back and forth until the beeping starts.
• Adjust the potentiometer WR51 so the beeping does not stop
when the screw is turned a quarter of a turn in either direction.
• If necessary, fit or remove a jumper on P55 to change the
intensity of the LTS emitter:
Jumper fitted
= Higher intensity
Jumper removed = Lower intensity
• Remove the label. The beeping should cease immediately.
• If necessary, readjust the potentiometer and/or change the strap
on P55.
• Break the program by typing X on the host.
When the label-taken sensor works properly, put back the left-hand
cover and close the front hatch and right-hand door. Then the printer
is ready for operation.
