Error when starting to print

I received the folloing message on the screen of my P1S and cannot resolve it.
HMS: 07ff-2000-0002-0004.
I thought there might be something wrong with the extrusion nozzle so have replaced it with a new nozzle and I am still receiving this error preventing me printing. Any help in resolving would be very helpful.

Usually means there is there is something stuck in the filament sensor.

Here is the wiki of how to get to the sensor.

Thank you for the link. I was able tpo pull out an inch long piece of filament from the sensor.
