Thick Paper/Extra Thick Paper; Transparencies - Epson EPL-N3000 Reference Manual

Note:
You should only use labels designed for monochrome laser printers
or monochrome plain-paper copiers.
To prevent the label adhesive from coming into contact with printer
parts, always use labels that completely cover the backing sheet, with
no gaps between the individual labels.
Press a sheet of paper on top of each sheet of labels. If the paper sticks,
do not use those labels in your printer.
You may have to make the setting Thick for Paper Type in the Setup
Menu.

Note:
When printing on thick paper, outputting it to the Face-up tray is
recommended because thick paper curls easily.
