Ferdinand,
You can use the L_TwainSetCapability function to set the value of ICAP_PIXELTYPE capability to TWPT_BW.

The help topic for the L_TwainAcquire contains a sample on setting ICAP_XFERMECH to TWSX_NATIVE. Setting the pixel type to BW should be similar because both have a container type of TWAINNUMERICTYPE_TW_UINT16.
