I have installed a new formatter board and a new hard drive into a HP LaserJet M4555. I have downloaded the most recent firmware per the HP site (ljM4555fw_2302243_421964.bdl) but when I use a USB flash drive to update the firmware I get a message that says Unsupported Bundle. I have tried 2 different formwares and each time I get the same error.
Does anyone have any siggestions as to what is causing this?
Thank you in advance.
