Printer errorDevice Failure - When I insert label paper, it comes out as cut in the middle.

When you insert label paper in the printer that supports the sticky paper only, it comes out as cut in the middle.
The printer that supports label paper is marked “LABEL” at the front.

It may happen rarely, but with a cartridge defected, the paper may come out as cut in the middle. In this case, it is recommended to replace paper.
If you have another label cartridge, check if the same symptom happens with it. If so, printer failure is highly probable.

If your printer or cartridge fails, contact the seller you purchased to exchange it.
