    richo 3235c makes whole page BLUE

    when I print black and white the pages looks fine

    when I try and print any document with colour on, the first page has a slight blue tinge but as the document goes on the pages get more and more blue.

    What is going on, this problem just started happening and then has got progressively worse?

    Thanks for any help

    It is the cyan pcu failing, try switching it with the yellow to se if you get the error in yellow instead.

        All you can do is to clean the charge roller,cleaning blade and toner waste skewer with housing of cyan pcu.

            I faced the same problem with newly cyan pcu then after 2 weeks the test pattern was with whole page blue I offered this solution for my same case.

                Dev units do 100k, don't they?

                  If they have less than 60K, you can get away with cleaning the charge roller. If not, you can clean it and then order a new PCU. That way you can replace it when the problem returns.

                    That'd be a PCU then.

                      Developer you can push as long as it is maintaining proper density and not starting to haze. I believe that on this machine you do one developer replacement and the next time you should replace the development unit.
