[sane-devel] Epson 1250U status report

[Gene Heskett]

Still not working, but I did find the source of the bus lockups 
that were requiring a reboot per scan attempt, even for previews.

The usb stuff on this TYAN Trinity 100 (S1590) mobo are 
apparently pure caca when attempting to move data in scanner 
sized amounts, I moved the scanner to the new box, along with all 
the sources and built it for that firestarter, the second machine 
in the sig.  I've now run 4 scans at up to 300dpi without any 
lockups so I believe thats fixed..

But the scans are trashed, the only actual data seems to be in 
the red channel, and its not 'dc restored'.  The lamp isn't given 
near enough time to warm up before stopping on the calibrate 
strip, which it may be missing, but I've no way to tell.  I 
suspect the next problem is to ask all on this list if they know 
what kind of a ccd assembly is in this Epson 1250U.  I've not 
opened it up, I read a horror story about someone who did and 
lost all the focus adjustments because of it.

It also isn't doing the lamp on/off correctly, and if its on from 
a previous scan, its shut off again for a 10 second portion of 
the calibrate routine and only comes back on about 2 or 3 seconds 
before it steps to the scan start position and begins the scan.

This was using the tar.gz's of backends-1.0.7beta2, 
frontends-1.0.7beta2, and xsane-0.84.
