So I've tried the lexmark driver on my X1180 and it works, it does have some trouble with the scan area.

From the information tab:
Driver Details
Vendor Lexmark
Model: X1100/rev. 2C
Version 1.1

Page Parameters
Paper Width: 432.14 mm
Paper Heigth: 579.80 mm

The specs from Lexmark say 216 x 297 mm. The scan area size is relative to the specs from the information tab, and the maximum SCANdal allows me to enter is 210 x 297.
