Ricoh mp c6000 toner add light

[stevel]

started with a add magenta light, decided to change entire toner assy from parts copier, then copier ran about 400 perfect color prints then went light and said needed black and yellow toner and black went under toned. re-installed original toner assy and got the black back looking fairly good but now it ask for new yellow toner.
is this a problem with several pumps being out on two toner assy's? having problem forcing on toner pump clutch. marked all for but when i tell it to run all only several turn.
any ideas?

Are you calling the unit that holds all 4 toner cartridges the toner unit?? If this is so, the toner supply clutches on this unit are known to fail. The either stick on and over fill the toner hopper or never turn on and do not add toner at all. This was also a known issue on the c6000's predecessor.........

yes i am talking about installing another toner unit assy which is the whole thing even had 4 oem toners. both the original unit and the used unit has a problem with wanting a new toner just different colors at different times. both unit i marked the pump clutch and then turned them on in the service mode and only a couple turn. i was going to get a pwb but ran out of time. the schematic shows all the clutches, sensors and motors go to a pwb in the rear lower side of copier. i guess i will return monday A.M. and try to troubleshoot each color at a time and then look into the pwb.
any other thoughts?

Sorry, we can't see your machine or what you've done unless you tell us.
So I have to ask, how's the quality of the voltage being supplied to the machine by the outlet you have it plugged into? Kind of sounds like it's not that great.

I would bet that you end up having to completely re-do the devs for the affected colours. seen it before.

your right, thanks for your understanding. i do need to ck the outlet. the copier is in a country town and they did not have copier on surge protector and prone to storms and not the good type. re-read service manual yesterday and they could give more info. i am going to start from scratch and check each color one at a time from developer to toner bag and clean sensors above drums. i will let you know. thanks

it is odd when i had the toner end shut off the black developer went under toned. i re-installed the original toner box assy and as i ran copies the black came back to being almost in spec when i left friday night.
this copier has been severely neglected and slowly bringing it back to good condition. this has lead to many problems and the customer is on a budget.
i am starting over from the start and clean all drums and sensors and toner box assy. i will keep the developer in mind as the drum does make a patch for the add toner to developer procedure.
any more info a help. thanks

My thoughts, this model range is not one that can be run on a budget! You are setting yourself up for non stop problems. You would be much better off trying to get in a good used MPC 5501 into this site. Did you sell the customer the original machine. This model range has to be serviced by the book, and even then you would be lucky to get half the rated life of most PM parts. i work on hundreds of these and their even more troublesome brother the 6501 / 7501 series.

For what it is worth, from what I've seen anyway, rust on a clutch means that clutch is done. As in the two metal pieces that connect to transfer drive are worn to the point that they won't connect.
I've tried knurling the surface of the clutch's flat plate, that used to work pretty well but not anymore. I've also tried reversing the flat plate as I had some success doing that with older doc feeder feed clutches, but that doesn't work any more, either.
If the rust came from something other than the clutch though, you should ignore this, as it is an unhelpful waste of time in that case.

your so right, budget and this model copier is bad. the life of the drums and related parts are also bad. plus she is using for all black and white copies as her ricoh 2090 is worn and wasted, needs rebuild. double punishment. i did try something new, brought back a toner assy and removed the pump for magenta and super cleaned it. put it back together and stuck a vacuum gauge on it and hooked up my drill to drive shaft. rotated it on low speed and high speed and it has vac so i reversed it and it also pushes air. so if this was a fuel pump it would be good.
thanks for the help, still trying to resolve, thinking board problem because clutched dont turn in service mode. will update. thanks
