Hi, Louis.

I digged a bit. It looks like the scanner is returning the wrong
identity at the MDL part:
[23:30:31.029950] [bjnp] get_scanner_id: Scanner identity string =
MFG:CANON;CMD:MFNP1,MultiPASS 2.1;MDL:Canon MF110/910
Series;CLS:IMG;DES:Canon MF110/910 Series; - length = 96
parse_IEEE1284_to_model function expects something like "MDL:MF110",
but here is "MDL:Canon MF110/910 Series".
Almost correct. The model description in the backend may be wrong. It
is always a guess what the scanner returns, but all scanners so far
returned only the model number in the MDL string. Try adding a line
with corrected model right next to the old one or just replace the old
one.
That was the first thing I did (see my first letter):
