I just updated from Rolf's PPA, and I am very happy to say that I can now
detect and scan from my Canon ImageClass MF644Cdw over the network. I
confirmed it can scan in resolutions of 75, 150, 300, 600, 1200, and 2400
for both Text and Color modes. It successfully read 2 sided multiple pages
from the sheet feeder.
The only issue I saw (same as earlier) is that when it completes a job
reading from the sheet feeder, SimpleScan pops up a dialog box stating
"Failed to Scan" "Error communicating with scanner." This does not affect
the job... all pages were scanned successfully.
Thank you everyone! I am happy to continue tests if there is energy for
debugging the error message!
