Welcome to the HP support community.

I understand that you are getting E3 error and follow these steps to fix the issue:-

heck for obstructions in the carriage path

Make sure the carriage path is not blocked.

1. With the printer on, disconnect the power cord from the rear of the printer.

2. If your printer has a battery, remove the battery.

3. Open the door to access the carriage inside of the printer.

4. Look in the carriage path for debris such as crumpled paper or dislodged labels, and then remove any that you find.

5. If the carriage on your printer has a latch, make sure it is closed.

6. Use your hand to move the carriage to each side, making sure it moves freely. If the carriage is stalled or docked to one side of the printer and you cannot move it, continue with these steps.

7. Close the carriage access door.

8. Reconnect the power cord to the rear of the printer, and then turn the printer on.
