The hardware does not support 50dpi, so ScanGear tells the scanner to
scan at 75dpi.

I abstracted the command handling to support different protocol variants
and released pixma-0.4.  Now the driver might understand your model as
well -- even though I had to guess many things, so you should not expect
it to run out of the box.  If the scanner loops with something like

	ff 20 00 00 00 00 00 00 00 00 00 00 00 00 00 10 
	Incomplete read

	cf 60 00 00 00 00 00 00 00 00 00 00 00 00 00 0c 
	01 00 00 00 00 00 00 00 00 00 00 ff 
	Incomplete write

	ff 20 00 00 00 00 00 00 00 00 00 00 00 00 00 10 
	Incomplete read

	cf 60 00 00 00 00 00 00 00 00 00 00 00 00 00 0c 
	01 00 00 00 00 00 00 00 00 00 00 ff 
	Incomplete write

you should try compiling with

$ make CFLAGS=-DUGLY_MP150_HACK

Same goes for MP450 et al.

Good luck,
