    ES-2500C - wierd problem

    Started with a bad sensor in the cyan unit. Replaced sensor and the over toned developer. Everything set up fine. Ran about 50 B/W copies no problem. Tried running a full color copy and no way. Jams every time at the registration rollers. Paper gets about 2 inches through rollers and lead edge is accordianed which says to me that the transfer belt isn't turning. There is no image on belt either.

    05-4719 results in CA00 - fault code is 255. Followed all steps in handbook. Position sensors test good. Could it be as simple as dirty position sensors? Why do B/W copies and prints run fine?

    As you can probably tell I have little Toshiba color experience. Need to keep customer happy because they are considering a new Sharp from me for another office.

    LOL I've already purchased the full set of manuals from you Paul.

    I've seen the K unit drum cleaner auger get so gunked up it actually stalled the x-fer belt resulting in the same kind of jams...could be the same issue with one of the color IUs...Separate each drum/developer and spin the drum...if the the auger is bound, you will see the arm on the fron of the drum unit try to spin around its axis...Emujo
    If you don't see your question answered in the forum, please don't think it's OK to PM me for a personal reply...I do not give out firmware and/or manuals.

      If it's not what emujo has suggested here with one of the colour EPU's, I'd check all the colour EPU main chargers. Quite often the end block breaks the peg which holds the electrode in place. You can usually tell if something is wrong by just opening the front cover and pulling the charge cleaners. If you don't hear the cleaner running over the top of the electrode, check that unit.

        both common faults: if one of the end blocks is gone say magenta the drum would be totally coverd in magenta when you pull it out more likey to be a seized cln unit on drum unit
        but hay could be both gentlemen

          Most of the time this is true, but the last of these I rebuilt had both these issues. She had sucked out so much dev, you could only just see where the auger had flicked enough onto the mag roller. It was a first for me to see broken charger with out the covered drum, which made me think twice if I was heading up the correct path.

            Agree that this is a problem with these boxes, but he wouldn't be able to get past the initalize sequence with a broken charger block...X-fer belt would flood with CMY, or K and generate a "C" code...he can make B&W prints, jam shows up in color mode..suspect something color EPU related, or X-fer belt when it goes into color mode.

              Thanks for all of the great input guys. I should have thought of it because I've seen it happen on Sharps when a color drum blade flips.

              It was a broken scortron. What idiot would design it with such a weak little tab under so much preasure?

              There I was without a new replacement. Thought I would share in case any of you run into the same issue. I used my finger drill to drill a small hole throught the side of the block and shoved a plastic pin (cut from a fuser pawl) through the hole and end of the scortron. Then melted it in place with a soldering iron. The scortron was kind of loose but it worked great. It'll hold until the new part comes.

              Thanks again,
              Dan
              P.S. Controller told me they intend to order the Sharp!
