HouseLabels 4" x 6" Thermal Printer Cleaning Cards for Printheads Compatible with DYMO, BROTHER, ZEBRA and Other Thermal Printers, 1 Box of 25 Cleaning Cards

This ought to be a pretty straightforward deal, but it's not. The cleaning cards are hard to get engaged by the printer. Even after running a card or several through a few times and cleaning the mechanism as suggested (thanks YouTube), the printer still skips blank labels. Where does the fault lie? The printer would be my primary suspect.

They really work. They got my dymo 4 xl working again, paper was feeding like crazy, i inserted the cleaning cards and got it to restarted. Now it prints and it doesnt get jam.Really recommend this product.

Didn't fix my issue but worth a try and did improve the situation a little bit.

worked great solved my problem of the printer telling me it was out of paper, when it wasn't.

just as advertised - work great!
