Error message E to 3 repeatedly

[thjsp1]

I have an HP ENVY Pro 6455 printer while has been working great until I had a couple of paper jams.  After that I cannot print anything and the error message I get is an E to a 3.  This error goes back and forth quite rapidly.

Welcome to the HP support community.

I understand that you are getting E3 error on the printer, I am glad to assist you.

The printer shows an E3 error when there is a carriage jam, follow these steps to fix the issue.

Check for obstructions in the carriage path

• Make sure the carriage path is not blocked.
• With the printer on, disconnect the power cord from the rear of the printer.
• If your printer has a battery, remove the battery.
• Open the door to access the carriage inside of the printer.
• Examples of carriage access doors
• 
• Look in the carriage path for debris such as crumpled paper or dislodged labels, and then remove any that you find.
• Example of a printer with debris in the carriage path
• 
• If the carriage on your printer has a latch, make sure it is closed.
• CAUTION:Ink tank printers: If the latch is closed, do not press down on it.
• 
• 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.
• Close the carriage access door.
• Reconnect the power cord to the rear of the printer, and then turn the printer on.

Reset the printer

• With the printer turned on, disconnect the power cord from the printer.
• Unplug the power cord from the power source.
• Wait 60 seconds.
• Reconnect the power cord to a wall outlet and to the printer.
