HP Smart Tank 790 All-in-One/Error 8AF30001

[Ronak7677]

I am getting an error code on my HP Smart Tank 790 All-in-One. The error code is 8AF30001. I tried doing this step.
With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
Remove USB cable, if present.
Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
Turn on the printer and wait till warm-up period finishes and the printer is idle

Nothing works. Then i tried to reflash the firwmare by first keep pressing the power button then plugging the cord. Got a menu option to reflash. As soon as i click on reflash  firmware, i get error message 12345. Computer can detect my printer as a HP reflash as other devices and not as a printer. Bcoz of this i cant reflash the firmware too. Please help.

@Ronak7677, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding HP Smart Tank 790 All-in-One/Error 8AF30001! 

We're thrilled to have the opportunity to assist you and provide a solution.  

That error usually points to a firmware or system board communication glitch. Since the printer is being detected as HP Reflash instead of a printer, it means the device is stuck in recovery mode. The error 12345 during reflash is the printer’s way of saying it can’t complete the update on its own.

Here are a couple of things you can still try:

Make sure you’re using a direct USB connection to the computer (no hubs or long cables).

Use the HP Firmware Recovery Tool (Windows only) – this is designed for exactly this situation when the printer is seen as "HP Reflash".  

Hope this helps! 

Take care, and have an amazing day!
