How to fix a 79 error on hp laser jet 1536dnf mfp

[Jill240]

Have already tried the turn off printer, wait 30 seconds and turn back on.  Doesn't work.  

Disconnected the usb cable and power cable.  Didn't work.

79 error just keeps popping up.

Firmware says no support or it doesn't download.

What's next?

Welcome to the HP Forums 🙂 

I would like to take a moment and thank you for using this forum, it is a great place to find answers. 

As I understand you have an error 79 on the printer,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

• Have you attempted to upgrade the firmware using the HP website?
  • If not, use this link for steps and details on getting it done: https://hp.care/2CLF9Zo

While you respond to that, the only other steps to do, is reset the printer to factory defaults and to help you with that, I have taken the liberty of sending out a private message that consists the top secret files/steps to perform the full-reset 😉

If the unit is under warranty repair services under the manufacturer's warranty will be free of charge.

Based on the results, the evidence points towards a hardware issue with the printer. You may try to remove the toners out and put them back in again and check if that helps.

HP LaserJet 1536dnf MFP keeps saying error 79  nothing different has caused it.  It just happened.  I have unpluged everything and re-pluged and followed instructions.  It keeps initializing says Ready but keeps doing the same thing over and over.
