CANON imageclass MF6550 for a year or so. The backends releasd with
Ubuntu 10.4 seems to be "almost" there.<br><br>Using the XSANE
frontend, for example, The scanner model is properly identified, and
the GUI allows me to request a regular scan or preview scan. <br><br>SYMPTOM:
When a (flatbed) scan is initiated, the scan head appears to make a
registration move, then makes a full 14 inch pass of the scanning bed,
and then returns to its home position.<br><br>The UBUNTU system "locks"
as though it is waiting for a data transfer handshake that never
happens. No image is returned. This is good for ONE attempt. subsequent
attempts to scan result in error messages. Disconnecting and
reconnecting the scanner from the system is not sufficient to "clear"
the hang. The ubuntu system must be reset.<br><br>So, I am able to
recognize the scanner, activate one pass of the scan head, and then
nothing. I tried this initially under 10.4 (32 bit) and after migrating
my systems to 64 bit repeated the test with the same result.<br><br>I
see that the scanner project wants testers for this model of scanner.
I would be happy to help, but I will need some hints (e.g. where log
files might be created. What command I should use to see sane process
status, a command line option that would isolate and test the backend
before we bring in GUI frontends to the mix.)<br><br>Ron
