    Ricoh 3035 image quality problem

    I just changed the pcu (opc,blade,developer) after some printing the density of the contrast black is getting lighter.And after 200/300 pages it give me message of out of toner but in the bottle there is more then half toner.
    I think i checked evertyhing
    -the toner bottle motor is working.
    -toner goes in development unit.
    -the bias from developer is ok too.
    -cleaned the toner hopper/unit.
    -no sc on machine.
    Any ideeas what can be the problem ?

    Check your logging data. Some SC's won't show up on the panel. They're only logged.

    By your description of going into add toner condition, it sounds like the td sensor is doing its job.
    Just some ideas to check:
    Have you tried to force toner supply through sp? if that doesent tone it back up, your problem is most likely within the toner supply part of things.

    Have tried to test the toner bottle motor (with the bottle installed) to see if you can hear the bottle turning?
    Sometimes there is too much friction in the hopper and will make it stall or not turn at all.

    The next thing you could check is to see if the plastic (flappers) that are glued to the bottle drive cup have come off ( very common ), some people actually use a small screw and reattach them so the never come off again.

    Clean the toner build up off the dev roller. Check the dev bearings are not shot and there is no staples or paper clips jambed in dev unit around the doc blade. Clean the bias connect tab and check that it makes contact in the machine.

    The pin from toner tray is not broken,inside the toner unit nothing is broken(mylars,seals)when i force toner from sp mode the quallity it is increasing a little bit but it is not dark black like it should be, after couple of pages it becomes lighter again.I will go searching in dev unit next couple of hours.

    Problem solved, the wire to the toner motor was detached and made contact on main frame iron, thats why the motor didnt work all time.

    Just a random question , you did run dev initialize when you replaced dev - have also had a long print run exit before I had a chance to initialize new dev which sent td sensor all over the place
