Any magicolor 3730 joy?

So I have a konica minolta 3730 printer... I unfortunately didn't do enough research before I bought it.

It is in fact a lavaflow printer, but not quite. It starts out looking more or less right (there is only one esc%-12345X instead of one per line), but then the raster data starts with escape code esc*b[number]W [DATA], instead of esc*b[number]V [DATA].

I've put example output at http://www.bobdbob.com/~tjohnson/misc/magicolor-email.dat

So before I really dive into it, does anyone have an already established clue and can go "Oh Yea...", and makes it go?

Thanks!

Looks like its RLE data, not JBIG.

Its not RLE... decoding it as PCL RLE doesn't make a coherent image. Nor does PCL TIFF (packbits?). If it were adaptive, the first command byte is 8, which also doesn't make sense (it would be 0 to 5).

jbgtopbm doesn't like it either.

My first thought looking at the *b1212M command was that it was just like a PCL *b[num]M with four numbers, one for each plane. That's not it. When I edit the file and change the 1212 to 1234, the file still prints correctly.

Maybe its jbig with no header...
