[sane-devel] Canon PIXMA MX890

[Henry Ptasinski]

With the latest sane-backends sources from the git repo, my MX890 is 
partially functional.  Using scanimage to scan documents on the flatbed 
works some of the time.  Some of the issues I'm seeing:

1. I often get these errors:

[pixma] bjnp_open_tcp: Can not connect to scanner: Connection refused

The scanner seems to sort itself out if I wait a while, or if I run 
scangearmp (I haven't seen any errors with scangearmp, however I very 
often get a popup that says the scanner is warming up.)

2. On one scan pass, I got this collection of errors:

[pixma] bjnp_recv_header: could not read response header (select timed out)!
[pixma] bjnp_recv_header: could not read response header (select timed out)!
[pixma] bjnp_recv_header: could not read response header (select timed out)!
[pixma] Could not read response to command!
[pixma] bjnp_recv_header: could not read response header (select timed out)!
[pixma] Could not read response to command!
[pixma] udp_command: no data received
scanimage: sane_read: Error during device I/O
[pixma] udp_command: no data received

but that problem has not shown up again.

3. The --resolution and --mode options sometimes work, but sometimes 
they seem to be ignored.  I think in those cases the scan is performed 
using whatever settings were used on the previous scan, but I'm not sure 
of that yet.


I haven't tried the ADF yet with sane, since basic scanning from the 
flatbed is still somewhat unreliable.
