HP Recommended
Product: HP LaserJet M4345 MFP
Operating System: Microsoft Windows 10 (64-bit)

This MFP Boots up with error DOWNLD NOW SEND RFU UPGRADE ON USB DEV PORT.

Original error was INFLATE ERROR SEND RFU UPGRADE ON USB DEV PORT, but after Clearing the settings we have the DOWNLD NOW.

Plugging via USB port to PC, an Unspecified Device is detected, 'HP LaserJet USB Upgrade' which looks promising. It appears to be 'ready and willing' to accept RFU.

I have tried every method on the Web, the Service Manual leaves out much.

Also, what is the DEV PORT? I noticed USB ports on the Formatter Board....

Any suggestions please on loading firmware ?

Thank you,

Flaggie
