Hi Ed and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, for the copy quality issue let's start with the basics; proposed preliminary tries (if have not been done) would be to change the settings to suit your preferred printout quality in copy mode; Auto, Photo or Text.
It may also be necessary to adjust the Contrast and the Brightness. In some instances, even the Color.
