I am not sure of the answer to this one and I see no one has responded, so I would recommend contacting our Support Department and requesting to speak with a Product Specialist. The Support options for your device are listed HERE.
I have the workcentre 6515. Latest firmware/software, latest twain, wia drivers.
Twain driver has no otpion to preview. Without preview it is difficult to scan smaller pictures from the flatbed.
WIA driver has a preview pane, but the image is too large - only small portion of a document is visible in the preview pane. So I cannot adjust the size properly.
I attached below screenshot of the preview pane.
I have a 4K monitor and screen resolution is 3840 x 2160, size / scale is 200%.
How do I fix it?
