I have a Kyocera FS-3640MFP with a continual "adding toner" message, I removed the right cover and everything appears to be in place all the motors and gears seem to be turning. To rule out a maintenance kit, I took the developer unit and drum unit and swapped them into a 3540MFP and they work ( a little over-toned),however, no adding toner message. I took the FS-3540mfp drum and developing units and placed them into the FS-3640mfp and the continual "adding toner" message is on the LCD screen. The firmware I believe is current 0514 and no error massages. I did not see any tech bulletins. Any ideas?

I brought it back to the shop and watched it for about 30 min stuck in that "adding toner" cycle. It basically fills the toner waste bottle while in the process. I'm thinking possibly main board issue.
Measure to prevent the “toner
low” display immediately after
the toner container installation
The “Toner low” message may display immediately after the toner container is
installed. As a preventative measure, the toner low detection method is changed
so it will be detected according to the level of remaining toner in the container.
Originally, the “Toner low” message displays based on the toner low count
detected periodically. In the case that the remaining toner level in the container is
high, the count number before detecting the toner low condition will be increased to
stabilize the judgment on the toner low detection.
this is from the bulletin
