[Misc] M3655 unknown toner

[Dark Helmet]

Howdy folks

Have a M3655 being temperamental with it's toner. We only use toner provided by Kyocera. No knock off stuff. Keeps showing up in KFS as unknown toner installed. Customer hits continue and the machine will function. We sent them another toner and she changed it and that one is saying unknown toner as well.

Would the drum cartridge do this? It has the little board on the left corner with 4 wires and 2 contacts that read the CRUM.

Thanks!

I have a UTAX branded M2040DN doing exactly the same thing.

Always genuine toner and parts.

So frustrating as it no longer reports toner levels in KFS. For the time being I have just sent an extra toner to the client and they email me when they swap. The device is over an hour away and my client is OK with this for now, so won't be doing a deep dive on it until I need to attend for a service call.

Sorry I have no further input, but I am interested in what others say on the matter.

First thing I would do - check with another drum unit.
