Customer asked me to look at his 951 . I take care of his Canons. According to him , The wrong tyoner was out in machine. He had someone come out and clean out developer unit and replace developer and wrong toner . Machine ran fine ,but copies got lighter and lighter . The toner was being used up in developer unit but not replenished.all toner feed motors working .So I ordered a tds sensor , thinking that the tech may have zapped it while vacuuming developer out.before leaving I filled developer with toner so customer could use. Came back put sensor in , no change. I have fresh developer to install, but before I do, how can I check to see if the patch sensor and or drum isn't bad, because ,to get him limping along I filled developer with toner again but now its throwing 2412.Im not very familier with Konicas. But he feels hes been beat up by the other company and only wants me to work on his equipment. So any info would be greatly appreciated . I have service manual . But I feel experience is best with this issue due to cicumstances.Thanks for taking time to help

Re: Bizhub 951 pro error 2412
Did your tech also clean out the toner hopper, vacuum pump, tubing, and sub-hopper? There's another two to three cups of toner in the system that probably did not get cleaned out.
It's the same basic procedure, just clean out all of the wrong toner, from the toner bottle all the way up to the sub-hopper and all the tubing, then developer and new toner, then stir. It doesn't take much wrong toner to screw up the whole process. =^..^=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.

Re: Bizhub 951 pro error 2412
I think like on the ricoh machines you have to goto multi output mode to "bleed" the system after clearing it out else the toner does not get to the dev tank in time?WhateverComment

The TCR Sensor is easily popped with a vacuum. I always remover them prior to changing developer. Try doing the developer calibration under drum peculiarity. I have found that if the sensor is shot, the calibration completes very quickly. It should take around 5 minutes or so if the sensor is working correctly.Comment

Codes related to toner delivery are locked just like a fuser code. Reset dip switch 3-1 to a 0 and it will reset the code. I also highly recommend that you purge all the toner tubes, and pumps (pumps are not interchangeable so don't swap them), and make sure that the cone shaped hopper under the toner bottle is clean and empty. Once a backup occurs it can wreak havoc on the entire toner system.
Good luck

Re: Bizhub 951 pro error 2412
Thanks so much Lee . I actually did reset that , but im not sure i did it right ? I found dip switch 3-1 entered 0 and turned machine off then back on? Did i miss a step? II guess the code isn't stored in the print controller bd? I assume if it was locked into a code that changing that would eliminate that but I guess not. So after entering 0 at 3-1 what would be next step?Comment

Re: Bizhub 951 pro error 2412
Once you change switch 3-1 to a 0(Off) and power the machine off and back on it should come to life. I just confirmed in the SM that C-2214 is indeed locked in switch 3-1.
C-2214 would indicate an obstruction between the main hopper (under the bottle), and the hopper that feeds the DV unit. The reason it allows 8 minutes is because it can take a while to prime the system from empty. I can't stress how important it is to purge all the toner tubes, motors and the cone shaped hopper. That cone hopper is a mixing section for air and toner. It shouldn't be full of toner. If you have a problem with that gear it is likely full and the system will never mix properly.Comment

Re: Bizhub 951 pro error 2412
If the toner concentration in the developer is to low it will continuously give the error and the toner transport will not get time to function.
Now it makes me ask the question if the developer was initialized or the right amount used?
Make sure there is a good brush on the mag roller.
You may need to tone up the developer and re-initilize the developer to get it going or use a new box of developer.
Add a table spoon of toner to the devtank at a time and repeat initialize until image density is ok.
Just to much toner and you will get a background.
The plug for the devtank caught me a couple of times before.WhateverComment
