Welcome to the HP support community.

I understand that you are getting an E3 error, I am glad to assist you.

Check for obstructions in the carriage path

Remove any loose paper or obstructions that might be blocking the carriage path.

• Turn off the printer, and then disconnect the power cord.
• Open the cartridge access door to get to the carriage inside the printer.
• EXAMPLES OF A CARTRIDGE ACCESS DOOR
• 
• Look for and remove any obstructions in the carriage path, such as crumpled paper or dislodged labels.
• EXAMPLE OF A PRINTER WITH AN OBSTRUCTION IN THE CARRIAGE PATH
• 
• If the carriage has a latch, gently press it down to make sure it is locked into place.
• CAUTION: Ink tank printers: If the carriage latch is secured, do not press down on it. Doing so might damage the printer.
• EXAMPLES OF THE CARRIAGE LATCH
• 
• If the carriage is not locked in place, move it to each side, removing any obstructions blocking its path.
• CAUTION: Do not force the carriage to move if it is locked or stuck. This can damage the printer.
• Close the printer door.
• Reconnect the power cord, and then turn on the printer.

Reset the printer

Reset the printer to recover from printer errors or failures.

• If your printer has a rechargeable battery, remove it.
• 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.
• NOTE: HP recommends plugging the printer directly into a wall outlet.
• Turn on the printer to complete the reset.
