HP 2840 Replace Drum won't go away

We have 2 printers. Drum is good (and new)(and works in other printer)

Cleaned the contacts (both sides), reset the NVRAM

Pulled the cartridges and the drum, left them and replaced

Flashed the firmware

No other trouble codes or error messages.

Anyone have any idea where I should try next????

Thanks in advance
