  If the LED lights up red (ERROR) and printing is interrupted, several factors could be at play. It could be due to an error in the software settings or print commands, a label jam, the label stock being finished, the print mechanism not being closed properly, or the print medium covering the sensor. In each case, verify these components and correct as needed. Also, ensure you are using a suitable print medium.
