These labels were terrible. I printed one sheet from our copy machine and it worked great. I thus tried to feed the rest of the 36 pages and it jammed every single one accordian style. I took it to another laser printer and after one sheet the printer was too hot and melted in the priter. I put it in a third printer and I could print the sheets one a time if I waited several minutes in between sheets. If I didn't the labels would melt to the roller and ruin the toner cartridge.
The package I ordered says compatible with Avery 5660/8660 which is what I expected. However the labels inside say compatible with Avery 5160/8160. Misleading packaging and I am disappointed. I prefer 5660 NOT 5160.
Do not use these labels. I tried three sheets of these labels all of which jammed my printer. I had used a different name brand before and had no problems whatsoever. Pay a few dollars more and get a product that actually works.
