Hello, > If you double checked the X74 is rts8852 based, you can send patches to the mailing list for the lexmark backend. How can i make sure ? I've had some very promising results. I was able to get scans at 75dpi greyscale and colour. So I guess that means it is rts8852 based. Right?
I had to adjust just a few registers which -I think- regard the scanner. But I had to change quite a lot of registers for the motor. The registers 0xe0 - 0xef are described in lexmark_low.c as "motor curve stuff". When I used register settings that all the other Lexmark models use the scanner head wouldn't start moving. So I used register settings for 0xe0-0xef I found by a whole page scan sniff in Windows. Could somebody explain to me how these registers work ? Especially: How universal are they. Can I just sniff the windows driver for all the different resolutions (75, 150, 300, 600) dpi for the two modes (gray, colour)? There is also a scanner mode where just the scanner head is moving with no light, must this have different motor curve settings ? best regards, Torsten -- GMX DSL Doppel-Flat ab 19,99 €/mtl.!
