To confirm that you are using a compatible power supply, follow the steps below:

Step 1: Ensure that the specification for the amperage and voltage shown on the power supply is the same as that shown on the body of your printer.

Step 2: Once you get a match for the amperage and voltage, ensure that the power supply connector’s size and shape match that on your HP printer.

Warning: Don’t force a connector that isn’t the same size or shape into your HP printer to prevent damage.

If the power supply is incompatible, get a new compatible power supply.

If the power supply is compatible, but your printer still won’t turn on, continue with the solution below.
