I was going to suggest the bulletin as already noted by another tech but also....remember to shake the toners when they are put in. People tend to store toners on their end and they cake up. Can cause false codes. I have also seen a bad toner motor on these before where it seems to work until you put a load on the motor and then it wont turn. Just a couple FYI.

Seen this issue a couple of times, with the same symptom where it ejects the toner.

BUT only on 50/60 models. Sometimes it helped with a new toner, though most of the cases it's been the sensor on the Middle Toner Hopper Unit.

This is a 3060 though, but maybe it can shine a light in the matter.

Check to make sure that the toner add hole in the developer unit isn't clogged up. I had one recently that kept telling them that the toner was empty, ejecting toner cartridge, throwing error codes, etc. Turned out to be a blockage where the toner enters the developer unit.
