This is a business class copier that will never have the same print quality as a graphics class copier. Experiment with different paper stock to see what else might give you better results. Others have covered this as well all with good points.

The feed problem is what I wanted to address. The bypass feed system is a simple roller/friction pad. This isn't the best (IMO) for trouble-free paper feed. Things you need to do are fan and riffle all of your paper that you place in the tray. All paper, and especially heavy paper, can be hard to separate. There are two issues you need to deal with, pages sticking together and the edges gripping/grabbing adjacent sheets.

I like to 'bevel' the stack of paper before I put it into the drawer or tray. The purpose is to move every sheet of paper at least a little bit from the sheet under it. The point is to break any bonds between each sheet. Sometimes you will have ragged edges that can hang onto the next sheet. Fan the paper, this will help break up any static cling and edge gripping. Finally, pay attention to the paper coating.

Can you slide the top sheets of paper off the stack with just your damp thumb? The copier might get a better grip on the paper. But, not by much more than you might think.

One more thing. If you want to run lots of weird paper through the bypass tray, learn to clean your bypass feed roller in between service call by your copier tech.
