NEED HELP!

just bought a new printer because lexmark didn't work. verified thru the following links that the canon pixma mp210 has two versions listed that show no noticeable difference in type, except for the fact that one works perfectly and the other partially.

http://www.openprinting.org/show_printer.cgi?recnum=Canon-PIXMA_MP210 (partially)
http://www.openprinting.org/show_printer.cgi?recnum=Canon-Pixma_MP210 (perfectly)

I am pretty sure I have it installed correctly but the fax and scan do not work with any programs I have downloaded:
xsane, kooka, scanner utility, gfax

The printer works fine, but it is an absolute necessity for me to have a scanner/fax as well.

please help me make sure the printer is installed correctly and figure out if I need to send this back or not.

I also need to know if there is ANY way to get a lexmark P3150 to work? I HAVE checked the list of printers that DO NOT work and it is on there, BUT I have seen some posts where people note that it can be done??? I have seen where some people have mentioned that you can backend install a z600 driver, but I cannot find how to do it.
