I have the opportunity to purchase a used L25500 which is missing the motherboard. The owner claims to have removed (and shipped back to HP) the motherboard as part of an HP trade-in program. Would it be possible to buy a used motherboard (for the sake of argument let's assume I can find one and it will work) and install it in the printer? Is there any reasons why it wouldn't work? I'm just concerned since obviously HP is trying to make the printer inoperable as part of the promotion (if there was such promotion?). Maybe it's just a sales gimmick by HP and they anticipate people making the printers operable again? I'm just new at this and don't have the money to buy a bricked printer. Any help will be greatly appreciated.
