[sane-devel] canon pixma MX890 ADF empty test OK

[Tim]

Unfortunately my report was premature.  The backend did successfully 
manage a 1 page ADF scan followed by an ADF empty test, but more normal 
use profile failed as:

o Placed 9 sheets in ADF

o launched xsane w ADF/multipage=9

o ask for and received preview, adjusted color with white eyedropper

o ask for scan, failed

After this, the MX892 was locked out regardless of several 
retries/variations including power cycling MX892, removing ~/.sane, 
removing cnijfilter and rebuild/reinstall 16 May git.  All variations 
error as follows:

Unfortunately this means the MX892 is unreliable and will be returned to 
Amazon.  I'll do my backend homework better next time.
