exemode A3-compatible flatbed scanner ScanBit MFS-A3 Body and AC adapter only There is some wear and tear. It seems to be an OEM of Mustek. I installed the driver from Mustek's overseas website a few years ago. (Whether it can be downloaded now is unknown) I checked the operation for the first time in several years when listing this item, and it was able to scan. Please note that I cannot provide any support.
