Filament not loaded

When I try to do my first layer calibration, I get an error saying that I need to load the filament first. However, the filament is loaded. I preheated the printer and loaded the filament. It was coming out of the nozzle and everything. But it still gives me the error. I tried unloading it and loading it and the same thing is happening. I also tried changing the type of filament but nothing works

RE: Filament not loaded

Check status of filamentsensor on LCD screen - should be 1!

I checked and it says that the sensor is on but it’s still not working

RE:

As Karl-Herbert stated: check your filament sensor. This error is caused by the filament sensor not sensing any filament in the extruder. If you loaded filament and get this error the sensor is your problem. It might be intermittent and not reproducible but it is. https://help.prusa3d.com/article/ir-filament-sensor-calibration-mmu2s_2245

Make sure FINDA works as intended too.

RE: Filament not loaded

Do you have a MMU2 installed?

Both sensors must switch stably to 0 or 1.

You can either monitor this on LCD screen or you can add an LED to the sensor, which simplifies the status control.

So, I used the linked that you guys provided, and my sensor does not change from 0 to 1 when i insert the filament. I took the extruder off and everything. The lever and ball bearing are moving. Do you believe I need a new sensor? or is there another way I can fix this.
