The fuser is not warming up.
On that machine under the web there is a thermal fuse on a white plastic mount, it has one screw through it.
It is most likely blown. Possibly caused by a jammed paper in the fuser.
That fusable link needs to be replaced.

hi you have a waste toner error code, the waste toner is apart of the drum unit in these machines so you will need to order a new drum unit for it.
easiest way to fix the problem.
