    Refresh me on the transfer rollers, I just replaced the paper transfer unit yesterday and didn't see a change and I do not see transfer rollers listed under the counters.
    Yeah I get that the other machine works but I would look anyway. The tech would need to replace the transfer rollers. There are the five that transfer the image from the drums to the image transfer belt and the bias roller that pushes the image from the belt tp to the paper. The counts for those are not in the user side they are only shown under the service mode. The image transfer ones are due at 1.8 million the bias one is 1.2 million and the belt is 1.7 million. Also all part ratings are based on letter size but your billing meter is only counting one for any size up to 13x19. If you look under system settings / admin / display print count you can figure out how many letter size pages you have done.

      Gotcha, I will check with him to see. I know he has done quite a bit of replacing things on both, a couple months back he replaced the transfer belt on both machines and redid the developer and some other things.

        For me I see the mottling get worse when I am half folding 11x17 newsletters, I have a standard finisher so the machine runs slower than molasses because it is half folding on the booklet tray, I have often wondered if the cooling down and warming up would affect it.

          Not saying to not do it but yes I think all that idling kills the machine! FYI there is a multi fold unit that can go on there. http://www.ricohbusinessbooster.com/...-folding-unit/ With the multifold unit it doesn't slow down like the finisher does.

            I use a plockmatic booklet maker so there is no slowdown and idling when running booklets. My Ricoh tech replaced the 4 PCUs today. Looked at the image transfer belt and said it did not appear to have any cracking or signs that it could be malfunctioning. Strangely enough, running a large color map on 15mil synthetic polyvinyl produced no mottling. But boy does the 7100 not like duplexing the synthetic media.
