Hi @VJTR,

Welcome to the HP Support Community. I'm afraid this is a hardware issue with the printer.

The steps that can be tried to resolve this issue are as below:

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Check for any paper jams or foreign objects inside the printer and make sure the print carriage is moving freely.

Perform step 1 mentioned in this document.

If the issue persists, leave the printer unplugged overnight and try to power it ON again.

Hope this helps! Keep me posted.
