What should I do if the red light remains on but no printing occurs?

If the indicator light on the ITP02 remains red and it cannot connect or print, please follow these steps to solve the problem:

1. Please check if the paper is correctly loaded into the printer. If it is not properly positioned, please refer to How do I insert paper?

2. Please check if the printer cover is tightly closed, and ensure it is securely shut.

3. Please use a pin to press the reset button and reset the printer.

4. If the printer still shows a red light after you reset it, please keep the printer turned on, drain its power completely, and then recharge it.

5. If the problem persists, please provide the printer's self-test page and contact us for further assistance.
