Dear Stef, Finally I managed to test the CS8400F. In the git version of SANE there is some implementation of the scanner. After adding proper line to genesys.conf I managed to make first scan with the CS8400F. Scanning was invoked using scanimage. Here are my observations: * If I do not specify size of a document to scan (no -x and -y options), the scanner head bumps into movement limiter (goes too far) * Scanner does not perform calibration and does not warm-up the lamp. It starts scanning immediately after the scanimage command. Once I limited scanning region with -x and -y options, I got image with vertical stripes (luck of CCD gain calibration?)
I am ready to work on the backend to make it usable. However, I need your help. In the SANE digest (vol 74, issue 19) you wrote: "Adding support for the Canoscan 8400F will be a matter of tuning the settings structures in genesys_devices.c and genesys_gl843.h. Then maybe adapt the code in genesys_gl843.c to support the possible differences for this model." Can you give me more specific hints, where should I add calibration, warming up? I have running WindowsXP in the virtualbox with the usbsnoop, so I can get any required usb logs. Thank you in advance, Best regards, Myroslav
