Why does the printer show a red light?

Red light is an indication that ITPP941 has a problem with your label. Most likely, ITPP941 needs to calibration your label.

① Load no less than 4 consecutive sheets of paper into the printer.

② After the paper is stable, press and hold FEED (red/green light), and when you hear a beep, release the feed.

③The printer will learn the size of the paper at this time, and the top of the printer will light up in green when it stops. After the process is complete, the printer returns to normal.

If automatic label identification does not work or red light remain, please turn off ITPP941 by using the power switch on the back and turn the unit back on.
