Rolf,

The ADF partially works.  I've been able to get simplex scans 
occasionally.  Duplex scans so far have only yielded the front page, and 
some errors such as:

...
[pixma] bjnp_write_bulk(0, bufferptr, 0x10 = 16)
[pixma] bjnp_set_timeout to 20000
[pixma] bjnp_read_bulk(0, bufferptr, 0x200 = 512)

When this happens, the display on the printer continues to say "Scanning 
document", and I'm not able to cancel out of the scan.

My recent tests were via network.  I'll attach the scanner via USB and 
try to collect some debug info.
