Absolutely worth it if you are under a maintenance contract; perhaps a little more difficult math if you have to pay for the upgrade. I previously had issues with Harmon Gloss, and now have none. Occasionally I had issues with other papers, but not anymore. HP had the option of installing the new rollers when I called them several times before moving from San Francisco, where they could have done it with a drive across town. Since they never got around to it, mine required a plane flight from Oahu to the Big Island and a rental car for the technician to get here. Whoops. That alone was worth the service contract for me.
Thank you sir. The only other media I had issues with was the Harmon but preferred PR Baryta anyway. I'll look into it. I have the doc describing installation. Should I have a Hp guy put them in?
