QTR-Quadtone RIP

This is my first posting here, so thanks to all who reply. I have searched high and low and can't seem to find the answer. My problem is rather simple. I started printing digital negatives for platinum palladium on an Epson 3880. The results were amazing. I replaced the 3880 with a P7000. That's when the troubles started. I installed the PSeries-UC-Install-P7000. I then modified the UCmk-EnhMatte-warm file. I used a starting point I had used with the 3880. I had learned the basics from the book published by Ron Reeder. The results from my base settings were very bad. There was little density. I then bumped up the settings and the negative looked very grainy, if that's even possible. So I must be doing something wrong. Has anyone been able to nail down a perfectly calibrated negative using a Surecolor P7000? If so I am all ears to suggestions. I have tried everything I know to make this work. Any and all help is appreciated.

Are you using the MK ink that Reeder initially recommended? If so, that is your first problem.
