    AF-1060 & 1075

    Light copies. Forced toner looks good. Run 600 copies on it and watch it get lighter and lighter. Released the toner bottle to watch the auger spin while the add clutch is coming on and off to add toner only in sp 2 mode, but when running copies out of sp mode the add clutch doesn't come on to add toner. Thanks t

    So the toner add clutch does come on sometimes? They are known for going out on that series - replace dev motor ass'y.

    Otherwise, so many things, mainly is it clean and up to PM spec? A worn drum cleaning brush can cause dusting on the ID sensor making it think there are dark copies, but it is just dirty and getting a bad reading. Check those areas, then if needed, replace the drum cleaning brush, and developer.

    If nothing else - clean the machine and replace the developer with fresh developer!

    This is probably a dumb question. Have you checked the Toner Density sensor. Does changing to Pixel counter make a difference?

    sensor

    yeah right, you must check the all the sensors thats regards with toner,, specially the toner sensor,,or else check the development unit

    Check the Toner End Sensor (Front of the toner hopper) these used to fail on the FT6645 machines which were essentially an analogue version of the same toner system. The effect was that the machine would exhaust all toner from the hopper without asking for more and give pale copies.

    The auger you see spinning is the Dev unit asking for toner. Is the bottle holder turning? If no the HOPPER is not asking for toner from the bottle.


    Also test the bottle motor.

    Test sensor using SP5803, SW13, Bit 6 0 = toner empty. 1 = toner present (wipe so it's clean)

    Toner bottle motor SP5804 56 Test with and without bottle in place.

    Make sure the m/s c is clean first of all. if the customer is using third party toner the id gets very dirty gives dodgy readings. chesk vsg etc. are they in spec?

    Is the toner hopper full and hard drive ? if yes.. try to dump the toner and clean the hopper then let the machine recover its toner level.

    fix the customer first then fix the machine... its simple and makes life more easy.

    So true, if you swing out the toner bottle, and the front of the toner hopper is devoid of toner, use SP mode to make the bottle turn and dump into the hopper (on top of the dev. unit). If it isn't dumping, I have seen a problem where something is wrong with that toner bottle unit. Could be the rubber seal, could be the white shutter in the way (be sure the brown outer cover is keeping it out of the way), could be the toner bottle motor.

    Yes, you can also cheat the front door, remove the toner end sensor on the toner hopper, (keep it attached), use input check to check it while you gently press against it to see if it changes states.

    Also, check to see that the toner separation case is good (change every 500-600K), there are 2 clear mylars on it that like to fall off, AKA toner recycling unit. It sits on top of the toner hopper. Make sure all of the gears and augers on the hopper turn and deliver recycled toner into the system.

    Remove the development unit and drum unit, shine your flashlight into the rear cavity of the machine, make sure the white cam/gear things that drive the gears on the toner hopper are not sheared off - I had this happen once too.

    Otherwise cheat the front door and make sure everything is turning as far as toner hopper shafts, dev unit, bottle, etc.

    Good luck!

    That's the one! And / or listen for the sensor "Tweeting"

    I've also had the chuck break on several different models so that the hopper doesn't pull the internal cap in the toner bottle, but that would also give you an empty hopper on the developer. Since it will force add toner and run for a while but not add toner on its own, I suspect a dirty / bad ID sensor (or if you're like me, I've left the drum unit unplugged before ) or the machine is set to pixel count instead of sensor control.

    Be careful in teaching your children it is acceptable to abort an inconvenient unplanned pregnancy because they may also determine it is acceptable to euthanize an inconvenient elderly parent.
