No sorry I do not work on the color ones. Have you been having a repeated problem ? I can look and see if there is a bulletin for it if you are.

I don't think Ricoh is highly revered in the color market Canon has the largest market share. I used to work for IKON and they sold Canon color machines and the color group had as many techs as any other group even though they had the fewest number of machines. All color copiers require a lot of maintenance.
