Having the EXACT same issue with the EXACT same printer! Using brand new, certified HP toner cartridges (HP security sticker in place) purchased through Home Depot and getting "Used Supply" messages, which prevent us from seeing toner levels, etc. Did you ever find a resolution?

Yes. Firmware is updated to version 07.250.2. And, yes, I have cleaned the contacts inside the machine.
For the record, I just replaced the toner cartridge this week, with an authentic HP toner (with seal). The previous cartridge worked fine (i.e. no "Used Supply" messages) and behaved appropriately. The toner cartridge before that (which was also an authentic HP cartridge) was read by the printer as "Used." So, it seems to be completely hit or miss.
