I don't understand it, either. :-(

Unfortunately, the problem isn't gone after the first scan -- it
persists until the scanner is power-cycled or a "send diagnostics"
command is sent. Also, the problem is present in all scan modes
(line art, greyscale and color -- didn't test the 12-bit modes, though)

That's a neat idea.

I got the SCSI command set documentation from Microtek's USA FTP site.
Reading it back-to-back didn't reveal anything particular enlighting
(except for that ugly "send diagnostics" workaround...)
I'll keep you informed.
