5.18 Low Label Detection Verification
Once the low label sensor is installed, it is necessary to verify correct operation. To test
for correct operation, place the unwind assembly inner flange in a position to block the
low label sensor beam. Press the jog icon and verify that no low label indication is
shown (Use of a three stage beacon or system status output is required). Rotate the
flange until the low label sensor beam is not blocked. As soon as the low label sensor is
not covered, the Low Label condition is set and is indicated by the appropriate output
signal. If the low label sensor is again blocked and remains blocked after five label feeds
via the jog or product sensor triggers, the low label signal is reset. Alternatively, the low
label condition will reset when the printer is changed from an offline to an online state.
No low label indication would be present at the three stage beacon or system status
outputs.
