I dislike replying to my own message; but I seem to have omitted the most important info. Duh: $ scanimage -V scanimage (sane-backends) 1.0.23; backend version 1.0.23 I have tried cranking up SANE_DEBUG_PIXMA in my environment. Confirmed that what kills it is setting --mode to anything explicit other than "Color" or "Gray" (as `scanimage -A` indeed promised, and the sources seem to indicate). Everything else seems to work. The problem surface is quite narrow. Samuel Adam

[sane-devel] [sane-pixma] Canon MF4150 v. PIXMA_CAP_LINEART
I know experientially that the Canon imageCLASS MF4150 is possessed of
a 1-bpp lineart mode. Pages fly through the automatic feeder, and text
is accorded an OCR-friendly crispiness lacking in the greyscale mode.
The Canon-provided Windows-only software provides two modes it
respectively terms "Black and White" (not too good) and "Black and White
Text" (much better).[1] I do not currently have a Windows machine
available, and I need to make some scans *yesterday*.
sane-pixma permits only --mode Color or --mode Gray with the MF4150,
and `scanimage -A` shows only these options.
What would happen if I simply ORed in PIXMA_CAP_LINEART at the
appropriate line in pixma_imageclass.c?
- DEV ("Canon imageCLASS MF4150", "MF4100", MF4100_PID, 600, 640,
877, PIXMA_CAP_ADF),
+ DEV ("Canon imageCLASS MF4150", "MF4100", MF4100_PID, 600, 640,
877, PIXMA_CAP_ADF | PIXMA_CAP_LINEART),
I expect this would lead to Bad Things, what with all the moving parts
I skimmed past. But is any other way to make it work right quickly?
Sorry to return ENOTIME on the project to actually familiarize myself
with sane-pixma code, beyond a simple grep. And thanks to the folks who
reverse-engineered the Canon protocols, so I can use scanner at all.

Driver". Check it, and options galore do arise.
