B801FC66 Error Code

[SMDoughty]

Error code B801FC66 keeps showing up on my HP 9025 printer.  Unable to turn off and restart the printer.  I have to unplug and plug in, and then manually reboot the printer.  Code keeps returning.  Anyone have a solution?

Many Thanks.

@SMDoughty,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Error code B801FC66 on the HP OfficeJet Pro 9025 typically indicates a firmware-related issue.Kindly follow the below steps:

Power Reset:

Unplug the printer from power.

Wait 2-3 minutes to allow any residual charge to drain.

Plug it back in and check if the error persists.

Check for Firmware Updates:

If the printer starts without the error initially, try updating the firmware via HP Smart or HP Support 

If the error prevents normal operation, try updating via USB by downloading the firmware to a PC and connecting it to the printer.

Check for Hardware Issues:

Remove and reinsert ink cartridges.

Remove and check the paper tray and duplexer  for any jams or obstructions.

If using an Ethernet cable, try disconnecting it and running the printer without a network connection.

Factory Reset:
If the printer responds long enough before the error appears:

Go to Setup > Printer Maintenance > Restore Factory Defaults.

If the error appears before you can do this, a firmware recovery may be needed.

I hope this helps.

Take care and have a good day.
