If your printer is jamming when printing labels on a laser printer? If the answer is yes, there are a few reasons that the labels could be jamming.
The first reason, which you can verify pretty quickly, is that you are not using the proper paper thickness setting while printing. To be able to print jam free, you need to set the paper thickness to “labels” in the printer preferences dialog box. Paper thickness can also be shown as “Media Type” or “Paper Type”. If “labels” is not an option then just choose the thickest possible paper thickness. This should prevent your labels from jamming, but unfortunately it will also considerably slow down printing speeds depending on the model printer you have. This is the most common reason for jamming labels.

The second reason, which is less common, is that there is debris, such as a label that has come off the sheet, and has stuck to any one of the rollers or on the fuser assembly. There could even be a whole sheet of paper stuck in the fuser which might be tough to see. You’ll have to open up the printer from all possible angles to check that. Check the places in laser printers like the top access door where you can take out the toner or a back door that is for thru printing (so that the rollers don’t bend the paper or labels).

Other reasons for jamming could be worn rollers, worn fuser, or gremlins
