I am trying to centre the page to make up for the ADF so I will sort that out and try again. The error 4 happens after the page is scanned. In my view the driver should do the right thing, though. I'll narrow this down a bit and get back to you. >> >> Another point is that the scanner seems to pause after some pages. Not >> every time, it might scan 6 pages and then pause for a second.

Haven't tried the windows driver, but I should be able to crank that up with a laptop or something. Will have to look up what buffermode is. > > also- can you verify that color scans look correct, and can you tell > the usb productID for this machine? > found USB scanner (vendor=0x04c5, product=0x1095) at libusb:005:013 For colour I seem to get 3 images side by side across the page. I can probably do a test page with separate RGB to send you an image if that would help. Maybe there is a new file format. Is there a way of getting JPEG data from the scanner? Regards, Simon
