Hello.
It is not possible to take advantage of the scanner(Epson Pervection
2400 Photo).
Scanning constantly breaks and it is necessary to disconnect and anew to
include the scanner.
I start process of scanning... Аfter a while, process interrupts.
Process of scanning comes to an end successfully very seldom.
Usually, successful scanning probably only on small images which can be
transferred from the scanner in a computer for time, without a
suspension of process of scanning for data transmission. But sometimes,
lags occur even during preliminary scanning.
