Jam
An optical sensor located in the stacker will detect each cut label as it leaves the
cutter. If a cut fails to occur or a label remains in the sensor sight path, the machine
will stop.
Full Stacker
A micro switch in the stacker rails allows the printer to detect a full load of labels in
the stacker. The stack full condition will stop the machine when the stacker is full.
Sensor Adjustments:
All the micro switches and optical sensors in your 676 printer were calibrated at the
time your printer was manufactured, however from time to time it may become
necessary to readjust / recalibrate due to the large variety of stocks and inks that can
be run on the machine.
Stock Out
With a full roll of stock loaded on the unwind with the unwind web guides properly
adjusted you should heard the switch click as you raise and lower the roll. If not the
switch bale is adjusted by carefully bending it as needed.
Print Registration Sensor Web Position
Adjustment
If you are running sense mark media with a hole or slot for registration the
registration sensor web position must be adjusted for the sense mark media being run:
1) Open the feed roller and print stations.
2) Move the sensor in line with the registration hloes.
3) Move the stock by hand in the feed direction until the registration hole or slot
desired is in under the sensor. The front panel LED with come on and off as the
hole or slot moves under the sensor. Position the stock just before the sensor mark
and the front panel LED is off.
4) Close the feed and those print stations needed for the format.
If your machine stops, for no apparent reason, while it is in the middle of printing a
batch, you may be missing sense marks (three consecutive tickets in a row in which a
sense mark was not found). Check for the following:
- The front panel will display a screen indicating that there has been a missed
sensor error.
1) Check that the web guides have been positioned properly on the unwind,
decurler bar and the web guide funnels.
2) Check that the feed roller pressure has been set equally across the roller.
3) Check that the feed roller pressure has been set to pull 11 inches of media
properly.
