starts, grinds, then all lights flashing

Have had this printer several years and has worked well. Now when sent a job (or turned on) it goes from a green status light, but then there is a brief grinding sound (I think I saw the front cover push out a bit for just a second) and then all lights are flashing (stauts is red, and 4 others are yellow).

Any thoughts very much appreciated.
