        ... you're not a technician, are you?

        If you have to ask what TCR sensor adjust is, you should be calling a technician. You'll just make it worse, if that is at all possible.
        =^..^=
        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.

              If you don't have a working knowledge about copier theory, a manual will only get you into a lot of trouble and cost as you will have to call a tech to fix the original problem plus the problems you create by attempting to fix it yourself. CALL A TECH!!!!!!

                    A professional technician would know that you never run TCR sensor adjust with used and very probably degraded developer. Before you make it worse, please, please, please, get some professional help. You can't do this by yourself. =^..^=

                        Re: error c2801

                        error code C2801 is TCR output abnormality, if you want to solve it just do toner auto supply.
                        in service mode, Imaging process adjustment and then toner auto supply.
                        if still appear and do trouble reset, off your copier and press and hold utility/counter and then on machine same time until trouble reset appear. touch trouble reset and off and on again.
                        i hope this can help u.. ^^

                          If u run TCR error 6 came. Just remove all developer from developer unit and put new developer. Then add toner . Again Run TCR adjust it will work. Best of luck

                              lets be honest here! most copier tech are oblivious, on what to do, you have to find a knowledgeable tech, most tech, play it by ear, or from the service manual, of course its not the tech fault, as company who hires him, and send him out, even though he might say he knows the machine just to keep his job, some tech just drags the issue, making it more costly, while yes there are a few good ones out there, its like a doctor, they are just guessing, unless you goto a specialist, even then, its guess work. sadly that the way it is.

                              i would clean the machine thoroughly, vacuum out all toner residue, literally its hard work, but you might have a bad seal leaking, or a developer seal worn away and toner is going everywhere, cleaning is only a temp solution, you must find the leakage either in the drum or developer. Its good to have a tech one that specializes in your machine. that like finding a needle in a hay sack. good luck.
