Kyocera 406ci Toner empty problem

[copydocinc]

I just replaced Maintenance Kit A (Black Dev, Drum, Transfer units, Fuser, PF Tires)
Ran through all the sims for adjustments and counter resets. Tested about 20 pages.
I also replaced the black toner, since it was already saying low and I could tell the cartg was empty.
Everything seemed good and I left my customers office.
About 2 hours later, my customer calls with these problems.
K,M,Y toners empty and replace My customer replaced them.
Then it says shake the K toner, Done
Then shake the M,Y toners, Done
Then K toner is empty, opened up pulled out toner and put back in, since it was still full
Then M,Y toners empty, Opened up pulled out both toners and put back in, since they were still full
Then it starts back at shake the k toner again and so on.
This cycle keeps going and doesn't ever come to ready.
I tested the toner motor and it works, can also here it after closing the door and it says adding toner everytime,
then the toner messages start up again.
I went back and all this continued with me as well, so I had to leave and now
I'm going back to upgrade the firmware, but not feeling good that this will fix it.

Any known issues on this problem or am I going to have toner drive unit problems to contend with?

Just had thread running on a similar issue. Read this and you'll have a great understanding of how the toner system works and what may be causing your issue.

By the way, if the toners are OEM and they're full but the machine is saying that they're empty, it sounds like something is blocking the toner path or you're losing drive somewhere between the toner motor and cartridges.

did you check U155/ Sensor output?
Value ~230-250
Did you remove the toner supply cover from new bk dv unit?

I did remove the toner supply cover from new bk dv unit.
I will check the toner sensor output.

It's just weird, since this happened after installing the new MK parts, which are only black related, but have problems with 2 of the color toners as well.

I agree that it is strange that 2 of the colors are showing toner empty but there's really only 3 variables.

1. Toner chip.
2. Toner motor
3. Toner path

I suppose I should include the toner sensor, too, but I don't think that's likely.

PS - Have you tried installing the old DV unit and seeing if the problem goes away? Try putting it back in and running enough pages to see if the problem has gone away. If so, that would point to the new DV being bad, IMHO.

When you did the kit was the machine unplugged? I know they had issues with these machines that people were installing the kits with them still plugged in and the new parts would not register correctly and there would be issues. I am not saying just turned off you have to fully unplug these machines.

Good point. I read a thread on here about that. If memory serves, I think the solution was to take all the DV's and Drums out with the power off and then trun the machine back on and let it code out. Then reinstall the new supplies with the power off and then turn back on.

Its a old kyocera quirk, if thats what it is.

Take all the toner out, close the cover. Restart the machine, wait until the screen say ready to copy, then put all the toner back in.
Happens from time to time.

I think with this you will have to install new parts again if they don't register correctly.
