Scan speed Epson GT-30000 for twain

[claude]

Hello
I use an Epson GT-30000, in the software provided by Epson, there is an option to scan faster or quality. This regardless of the dpi.
Depending quick scan it 2 seconds, as he scans in 12 seconds. (300 dpi for the two cases). There is no visible difference on the quality of the documents obtained.
I wish I could fly in twain from high speed. I can not find twain for this function. Could you tell me the function to use.
I must drive the scanner without going through the user interface.

Thank you in advance.
Claude
