We have a Phaser 3635MFP that has been working great for us as a network fax machine. However, I have installed the software on one station running windows 7 64-bit and the typical fax job type selection is not available in printer preferences. Every other machine we have (XP and Win7 32 bit) shows the option for a fax job. Am I missing something or is faxing not supported on the 64-bit software? Any help is much appreciated.
