What should I do if the labeling machine fails to label

What should I do if the labeling machine fails to mark the label? 1.
If the labeling machine fails to mark the label, first check whether the target measuring sensor is normal
.

If the target measuring sensor cannot sense that the labeling product passes through the conveyor belt, the automatic labeling machine will of course not issue the label.
If there is a problem with the target sensor, reset the parameter value or if the target sensor is damaged, it needs to be replaced with a new sensor
.

 2.
Check that the transmission synchronous belt of the conveying mechanism is not broken.
If the broken phenomenon occurs, a new conveyor belt needs to be replaced
.

 3.
Check whether the peeling scraper is not sharp enough and whether there is corrosion
.

 4.
Check whether the traction mechanism is open, and labeling can only be done when the traction mechanism is opened
.

 5.
Check whether the traction mechanism is loose.
If there is looseness, the traction mechanism needs to be tightened.
6.
Check whether the power contact of the transmission motor is loose
.

 7.
The problem of the label itself is also possible.
The label quality is poor or the irregular label can't make the label peeling scraper peel off the label
.

Then, is to see if you have turned on the power
