IRA-C5240 Black printing light Developer unit problem?

[copyhere]

Hi on a customers machine I was getting light black copies on the pages doing auto grad adj so i changed the black developer unit from a different machine and everything was good for 2 days then the customer calls back with the same problem the black is too light.
In the mean time i put the bad black developer unit in my own machine to try to troubleshoot it and it is doing the same thing light black image I tried doing toner stir for black multiple times auto grad adj. multiple times finally i tried black dev init and auto grad. and got no change. I was thinking that the customers machine may have a problem with the black toner hopper and is not adding black toner to the dev unit thats why the used unit I installed worked ok for a couple of days.
My question is does the toner stir function actually add toner to the dev unit or does it just stir it? I am at the point that changing the dev unit fixes the problem but it does not last and then the new developer unit becomes bad. Anyone know what the heck is going on with this machine. Thanks

It should add toner when running stir. I would guess that the black toner hopper needs to be replaced.

I Brought the original developer unit back and put it in the original machine that it was working in and now it is making almost completely blank black copies I tried auto grad adj and now a good dev unit is bad. I tried to make 300 sky shot copies to try fill with black toner from the good machine but all copies are coming out blank. So I dont think the problem is the toner hopper of my customers machine.

After everything that i have tried to solve this problem I am thinking what if bad toner was put in the machine when you replace the developer unit the bad toner could make the new unit bad. If that is the case the toner hopper has to be replaced or cleaned out. is there a way to empty it through service mode or does it have to be physically removed?

What's the life on the dev assy if was other dev assy done the same thing straight away its properly the plastic drive coupling. When swapping over dev units you need to iniset

The replacement one worked perfect for 2 days then got bad thats why i suspect it is bad toner. then when i brought back to my good machine it stayed bad.
What do you do when a customer puts in bad toner and you have to fix it? I dont know if thats what happened but im pretty sure bad toner is the problem.

My friend it is not a starter issue (Dev issue) , it seems a toner issue as u specified . you can easily open the developing units and see that the toner level is very low .

Bad Toner will damage the hopper and cause such problem . you will need to change the hopper along with its motor .

If you will return the old dev to his machine soon it will give black images also .

Stir Doesnt add toner to the developing unit . it only stirs the toner inside it for some time .

If you can find Sply-H make sure only set to the black . perform it, it will take some time . then manually check the dev if it is filled with toner . if not then change what i specified for you above.

You might need another good developer. but i prefer not , it might work without it .

Good Luck

You don't have starter on this machine it's a complete dev assy.
If you have a faulty dev assy with bad TD settings if you replace with used dev assy it will use the same readings for TD sensor you need to set up as new. I would replace with new Dev assy then go to toner hopper assy as the dev assy would be the most common fault.

Good luck

Re: IRA-C5240 Black printing light Developer unit problem?

there is starter in all developer units , but they dont come as separate parts if that what you mean.

Developer units fail if the starter becomes weak , or any damage to the magnet roller .

at this point of the issue , if you are willing to risk another developing unit would be your choice .

I suggested him some troubleshooting to narrow up the issue more with the least risks.
