Glory tabletop vending machine VT-S10 VT-S20 This is a circuit board removed from a VT-S10 that was operating normally. It can be used if you are unable to print on a VT-S10 or VT-S20. According to the Glory representative, if you can't print, the cause is likely the circuit board or the printer. There is a VT-B10 sticker on the back, so it might be usable on that model as well. There is no guarantee that the printer error will be fixed, so please purchase only if you can make your own judgment. Also, please understand that I cannot answer questions such as "Will it be fixed?". Replacement only requires removing two screws and replacing the cord.
