I found an official spec document
Resolution ■ TWAIN: 75 x 75 dpi up to 4800 x 4800 dpi ■ WIA: 75/100/150/200/300/400/600 dpi ■ Resolutions other than the following are achieved by driver's resolution conversion. 200 x 200 dpi 300 x 300 dpi 600 x 600 dpi 1200 x 1200 dpi
Anyone know where I can get a TWAIN driver for this scanner that will work on Windows 10? If not, then how can I get the WIA driver to scan at 1200?
