Constantly get critical error. 6155e Will not print

[DKor]

I’ve tried many fixes suggested by HP. Nothing works. Unplug and restart works for a few days or a few hours. Tried factory reset. Tried setting up again. Firmware up to date. Tried having tech take control of computer and change settings.
This is entirely unacceptable. HP does not know how to fix. Tried printing from Mac, iPhone, iPad. They will all work for a bit but then nothing. Printer goes to sleep or gives the error code. F0.01.04.07 over and over and over.

That appears to be a firmware error.  Looking at 6155e it seems new firmware was released March 13, 2025

Connect the printer with a USB cable and see if you can reinstall the firmware.  Possible something when wrong.  Did you upgrade the firmware manually, or did windows automatically update it?  Did you get a firmware warning it was being upgraded?  Sorry, I have no experience with MacOS

If that does not work then try reset

if none of the above work and it was working before the firmware was upgraded then contact HP agent and ask if the firmware was the problem.  

How to contact an HP agent:
Sign in to your support page
Select the product you need help with and scroll down to support options.
Select "Contact us". You can change country and language if necessary.

let me know what you find out.

Thanks for the suggestions. I’ve done the reset. Nothing seems to work. Now HP says they will start a return for me. We’ll see.
