I have working print drivers for my Lexmark X7675, but I can't get it to scan anything. Simple Scan and XSane both say they can't find a scanner. And my scanner doesn't recognize my computer. (Printer is on the network and not directly connected.)

Later on I will try directly connecting the scanner to see if that makes a difference, but judging from similar posts, I don't think it will.

Is there any way to get it to scan? I can work around it for now by scanning to a USB pen drive, but it'd be nice to be able to skip this step.
