Gestetner 3227 add toner problem

[pinetree]

Gestetner 3227, It keep saying add toner, even there is new toner installed, so I replaced new drum unit, add toner light went off but made about 30 copies "add toner" display again
anybody know what caused this ????
Thanks

Sounds like a toner motor problem, ckeck its output in SP mode 5-804-005. Occasionally when this motor goes it takes down the i/o board. Also dismantle hopper and give a good hoover out to remove possible compacted toner.

[CopierTechofOmens]

If the machine continues to display add toner check the operation of the toner near end sensor. The toner near end
sensor is mounted on the front of the developer unit. When the toner near end sensor is removed there should be toner
present behind the sensor, if there is no toner, there may be a problem with toner transport from bottle to the toner

hopper. If toner is present there may be a problem with the toner near end sensor.

thanks for reply, I will try those on monday and will be inform
have good weekend..

thanks again

did you make sure the stopper from the old toner bottle was removed?

Also to chime in on the "hoovering" when doing the hopper. Re&re the hopper assy clean it well so it can spin "freely". I've seen them bind up on there own.. even with a good toner add motor. Had them completely dissassembled and cleaned all of the old toner out. Added a very small amount of krytox (ricoh guys know this stuff) lube around the rim of the rubber seal and the hopper itself (where the seal sits on). Help very much with "fake" add toners.

Occasionally the mylars will come off inside the toner supply unit and cause this condition. In this case we replace the supply unit as they are relatively inexpensive. As techspecs states, it could be the toner motor also.

We've had a lot more problems with the mylars peeling out of the hopper than with bad toner motors - IMHO if you have any problem with the hopper just replace it - it's a mess to mess with will probably fail soon after you put it back together anyway.

Don't search too hard to find a toner end sensor 'cos there isn't one.
the usual cause is that the toner has not been supplied to the pcu for some reason-usually the stopper is left in the bottle chuck from the previous bottle. the toner is then depleted from the dev and when the td sensor goes below 2.3v the toner light will come on. if the machine is used without replacing the toner bottle the dev becomes so depleted that it does not recover. Remove the hopper from the machine, cheat the door interlock and run output check on toner motor. If that is ok put the bottle in the hopper and turn it in operational direction while holding open the shutter. Toner should spill quite readily so have a cloth or paper there to catch it. If all is well there I would then run forced toner from the service menu a couple of times to tone-up the dev. Once the toner sensor approaches it's correct value opening and then closing the door after a short delay should prompt the toner motor to turn and toner will be added until the correct voltage is arrived at.

check toner hoper there should be a cap. if there is not check your toner droping from hopper . motor is working properly coz you made 30 copies. in short svice your toner hopper.

[neocozhu]

check the toner supply mode . print smc report to see there is any problem.

open the hopper tank and full service back. after see the reading at 2-220
check the standard Vt value.

The machine let him make 30 copies because of the toner in the developer that the machine uses to get it's voltages right during the initialisation of the new PCU. It used that, then asked for more. I'd be willing to bet it's the toner motor and possibly the BICU board.

My plan of action would be as follows:-

1/Check the action of the green handle, is it stiff and difficult to push all the way down? If it is then you've got two options, replace the entire toner hopper assembly which is the quick and clean way (but expensive) or strip the complete assembly down, vac out any compacted toner and clean and lubricate the chuck and slider to make the action nice and smooth. Whilst you're in there check the mylars on the hopper cap haven't gone walkabout.

2/If the handle isn't stiff, then take the hopper out of the machine and put the bottle to one side. Look down into the chuck or as I prefer to call it the "cat's anus" (you know what I'm talking about ) whilst you operate the handle, make sure that the anus opens fully when the green handle is fully up. If the anus isn't opening fully, then it won't be gripping the bung to open the toner bottle. Cure is pretty much the same as point 1.

3/ When you said you'd replaced the Drum unit, did you just replace the drum or did you replace the entire Drum/Dev assy with the Type 320 PCU? If you did then disregard the rest of this point.

Check the neoprene seal on the pcu entrance hasn't gotten chewed and ended up in the toner path

Check that the plastic arm that opens the PCU entrance shutter hasn't got snapped off. If it has then just remove the shutter door and it'll work anyway.

If there's a pile up of toner in and around the PCU entrance, then separate the drum unit from the dev unit and check the dev unit auger gears. The 3227 PCU is pretty much the same as the 1015/1018. If dev gets into the auger gears it chews them to bits and the mixing augers won't be moving the dev around.

4/ If all of that draws a blank, trick the front door and either turn the toner bottle motor in output mode, or let the machine go through it's "add toner" process. Shine your torch down the toner hopper cavity and see if you can see the bottle motor turn. If it doesn't then you'll need a new motor and more than likely a new IOB.
