I am using a MacBook Pro running Snow Leapord 10.6.8 and have the most up to date drivers from FYI for the ES6530C (Also, I have downloaded and installed the "Extra Features" drivers from FYI). I am using Adobe Photoshop/Indesign/Illustrator CS5.5, but have also tried to print using many other applications such as Preview. 
I am using some thick cardstock paper and no application gives me the option to use the bypass feed tray. Using the provided drivers, under my system settings > printer settings it does not show all of existing machine features. If anyone has any knowledge about how or why I am not able to access all of the machine features from the MacBook, assistance would be greatly appreciated.
Thank you
