Dear customer,
please make sure the other scanner is no longer shown in your device manager (win) / system profiler (mac).
The G4050 must be the only device shown there.
For devices attached by network connection the control program might have to be uninstalled because the driver is not unloaded by shutting down the device..
Also make sure you are using an operating
system which is supported for your scanner.
kind regards,
Arne Ketelhohn.
