When I use memory transfer mode on 10.8 , ImageKit calls my scannerDevice:didScanToURL:data: with an NSData object containing TIFF data that can be used with +[NSBitmapImageRep initWithData:].
When I try the same thing on 10.7, the NSData isn't TIFF, it looks like this: $ hexdump -C -n 256 ~/Desktop/Canon-MG4220mystery 00000000 70 00 00 00 01 00 00 00 f0 09 00 00 e7 0c 00 00 |p...............| 00000010 d0 1d 00 00 01 00 00 00 08 00 00 00 18 00 00 00 |................| 00000020 01 00 00 00 00 00 00 00 01 00 00 00 2c 01 00 00 |............,...| 00000030 73 63 61 6e 6e 65 72 2e 72 65 66 6c 65 63 74 69 |scanner.reflecti| 00000040 76 65 2e 52 47 42 2e 70 6f 73 69 74 69 76 65 00 |ve.RGB.positive.| 00000050 ee ee ed f0 ee ed ed ef ee ef ee ee f0 ed ed ef |................| 00000060 ed ea e9 f0 ed ed ee ee ef ef ed ee ec eb f0 eb |................| 00000070 21 20 22 21 20 22 20 1f 22 23 23 22 22 20 22 23 |!
