Check Toner Cartridge TaskAlfa 3510i

[CiroB]

Good morning,
I have a problem with a TaskAlfa 3510i.
As soon as it starts it reports error to check the toner cartridge.
I have replaced 3 toners (original) but it still reports this error.
I have replaced as per the technical bulletin the cartridge sensor present in the belly of the MFP.
I have replaced the engine board.
I have replaced the main board.
I have replaced the power supply board.
All did not lead to the resolution of the problem.
Any other suggestions?
Thank you.

does the machine attempt to fill the developer at all before giving up or is the error immediate?
Is the machine in a smoky or dusty environment?

The machine attempts to fill the developer after which the error appears.
The machine is currently stopped in our service center.

try a developer.
also check that the developer is actually turning, same for the toner container by putting a mark on the drive gear.

This problem is generated by the sensor opt and the sw push behind the toner. You can try to clean them or chance directly.

Can I check this in u150?
