[sane-devel] ADF problem on HP ScanJet 8270 (ERR: Scanner cover is open)

[Valentine Christian]

I have essentially the same problem on my HP 8250 scanners.  The only
effective workaround is to power down the scanner, connect to an XP (or
other M$ product with HP drivers installed), and start up the wizard.  It
manages to take the scanner out of the error 15 state, and I can move along
until the next paper jam or other error condition.
