Hi @Feliciaoyekola

Welcome to the HP Support Community. I'd be happy to assist you with the "Carriage Jam" error.

Check for obstructions in the carriage path - 

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.

If the issue still persists, try these steps - 

1) Take out the cartridges.

2) Unplug the power cord from the printer & wall.

3) Wait for 30 seconds. 

4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector.

5) Insert the cartridges back into the printer.

Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware
