IRC 3220 C1 Trouble

hello,

I have a image-PASS C1 server working with a Canon IRC3220 printer and have a trouble:
In the driver options, if I select A3 size, the printer select A4 size, and if I select A4 size, the printer select A5 size.

I'm using the EFI driver 2.0 on windows 7 32bits.

This issue occour in only one workstation, in the others workstations, the driver work correctly.
I use windows 7 32bits in all workstations.

Sorry for my bad english.

thanks
