XEROX PHASER 7500. Printing card stock

Hello. I was hoping someone might be able to guide me in the right direction. I have a 7500 Xerox printer I recently acquired. I do not do much printing but I am trying to print out some not too heavy card stock but the ink does not seem to fuse to the paper and I've tried a few other types of paper that are Xerox certified. My old Xerox are used to have a setting in the print dialogue box that I could choose heavy card Stock but I do not see that in my print settings so I'm wondering if I'm missing something? Thank you in advance for any help.

 

Hi. I do not remember a menu tree structure but I am 100% certain that there is a setting for a card stock in this printer. Also, if there is a PS Driver available - use it.
