    Hi All,

    So OK I rebuilt the drum unit (New Drum, Drum Shoes, Drum Cleaning blade, new MC Grid, New Needle charger) Cleaned and replaced developer. Mag roll was pristine.

    Started to do 05-2404 to set the developer ands once again C380 code. Wiped out another drum unit. Last thing to try is the LGC board.

    Any suggestions please
    ?

    Try another drum UNIT. I have seen these frames crack and this model is no "spring chicken".
    These units are interchangeable, one screw, two clips to swap out the colored front piece.
    What are the auto toner sensor readings in service mode ?
    Pull and clean the ATS sensor during developer rebuild ?
    Verify / adjust doctor blade ?


    Failing to plan is planning to fail!!!

      If you get C380 right after the developer initialization I would suspect the ATS sensor. The top of the ATS gets scored in time by the wiper blade on the auger and can fail. In the picture attached I can see that the developing roller gear is kinda covered with toner - this is a sign that the developer leaks through the seals onto the gears. This can prevent the developing unit to turn and shortly you get the C380, seen this many times and usually is accompanied with gear noises.

      I've seen HVT boards to fail (not many) but none of them caused C380 related codes though, only CA00 or CE40's. This board is less expensive comparing with an LGC Board if you want to go that way but I will concentrate first on the developing unit gears and the ATS sensor, hope this helps.

      Hi Blizzoo,

      I have changed the ATS and harness on the dev. No leakage on the gear area, I checked.

      Thanks for the suggestion.

        Just for future reference, the blanking lamps are mounted below the drum in the main body of the machine. I think I would install the developing unit without developer, and a drum unit without drum or charger, then test the blank lamps. =^..^=
        If you'd like a serious answer to your request:
        1) demonstrate that you've read the manual
        2) demonstrate that you made some attempt to fix it.
        3) if you're going to ask about jams include the jam code.
        4) if you're going to ask about an error code include the error code.
        5) You are the person onsite. Only you can make observations.

            I might be wrong but if discharge lamps/leds are failing it won't pull developer instantly but slowly copy after copy.

              Hey Mojorolla

              did check the Doctor blade and all was well. Have replaced the ATS. Reading was 635. Well over the set limit.

                Typically with Toshibas, if you have a primary charge loss to any color, the toner in the developer will feed out onto the primary transfer belt in about 60 seconds ... yes all of it. But ... it usually leaves the developer particles intact, and when the charge problem is resolved the color typically tones back up without developer change.

                The only machines that I have seen dump the full load of developer instantly (15 seconds or less) are Konica Minolta bizhub C458, and it turned out to be a bad HVT. I may have changed only one HVT on a Toshiba ever, and it was for a dead short blowing the power supply.

                  Hi Tsbservices
                  yes that was my afterthought. But i must investigate all possibilities. I think i will source a drum unit and dev unit and try that to eliminate those possibilities befor i tackle the possibility of the logic board.

                    I will not let this woop me. Going back to basics and try replacement (known good ones). To eliminate each possibility.

                      I must admit I touched only few digital Toshys in last 10 years so please forgive my ignorance. If new developer was charged together with new ATS sensor and no drum-dev-grid shortages are found...unfortunately that leaves next logic board.

                        hi tsbservice.
                        i will try both different dev and drum units, known good. I will get this.
                        thanks for your input. All helps.

                          Testing the lamps can be done with all the parts inside, just cheat the front door interlock switch and front cover open/close sensor and don't leave the lamps On for a long time. You should have a good visibility over each lamp

                              Ok Update,

                              I have put in know good developer units and drum units, went to do 05-2404 and the same thing happened. Taking it back to the shop. have some good donors there and will try the logic board.

                              In the mean time I put a Kyocera TA 2552 in their area and maybe I can get them to upgrade....
