SECTION SIX – TROUBLESHOOTING
6.1 NOTHING WORKS AT ALL
1. Check main power. Is machine plugged in? Is main power switch turned on?
2. Check fuses inside control panel. Bad fuses will be indicated by the red LED on the fuse holder.
3. Are labels loaded in the machine? If the label gap sensor is “open” then an error circuit prevents the
motors from turning after 5 seconds.
4. Are speed controls turned up above zero?
6.2 CONTAINER IS DETECTED BUT NO LABEL DISPENSES
1. Is the Label Gap Sensor in the gap between labels or “uncovered”? There is an error feature in the
machine that prevents the motors from turning whenever the gap is open for more than 5 seconds.
2. The sensitivity of the Label Gap Sensor may need adjusting. If the Label Gap Sensor is a micro switch
it may need adjusting in, if the sensor is a photo eye it may need the sensitivity reduced.
6.3 MORE THAN ONE LABEL IS DISPENSED
1. Check the sensitivity of the Label Gap Sensor. If it is a photo eye then the sensitivity may need to be
increased so the photo eye will “see” through the web backing.
2. There may be too much “flag” of label, and the second label is getting stuck to the product and
pulling off the web by the product rotation.
3. The photo eye may be set so that the product is being seen more than once, and the machine is
labeling the same product again and again. You should be able to see the machine “cycle” in
between labels, with a small pause.
6.4 WEB KEEPS BREAKING
1. Check the label web (backing paper). Is it scored, torn, or creased? If so replace with another roll
of labels and try again.
2. Check the edge of the Peel Plate. Is there a burr or sharp edge that may be cutting the web? If
so then take a piece of emery cloth or very fine sandpaper and lightly sand the edge.
3. Check the travel of the label path. Sometimes the label web may get “hung” on a Web Guide or
be binding in a way that will cause the web to break when the Pinch Roll engages. This will cause
it to break at the Peel Plate.
6.5 LABEL TRACKING IS NOT SQUARE
1. Check the path of the label web. Is it tracking straight? Are the Web Guides holding the web at a
consistent height through the machine? Adjust accordingly.
2. Check Web Guides to ensure that they are holding the label web down.
3. Check the Peel Plate to be sure it is square in relation to the conveyor.
4. Check the Drive Roll to see if adhesive build-up is causing the label web to be pulled up as the
label web is pulled through the Pinch Mechanism.
