Hi Spike,
I have attached the sample file. You may try on it. Press “Acquire” first time – Console show OK and scanned image ok. Second time – Adjust Contrast Value by Scroll. Scanned image seem ok, but console error show as below. But not sure whether I can ignore the console.

I’m sure I can set apply ICAP_CONTRAST on first scan. Once I trigger the scanner scan again and its prompt error. But I found that I only able to control the Contrast by using UI (setShowUserInterface(true)).
I have tried 3 different model scanner (Kodak i65, i1420, i2600).
