Hello and welcome to Just Answer. My name is Wes and I will be assisting you today.
It sounds like the print carriage is jammed, if you can open the access door to the print head, you can try to carefully move it left or right to see if it unjams. If it doesn't and shows no signs of movement the printer will likely need to be replaced.
I have taken the top off but without a diagram I cannot see where the print head is. I have tried prodding whatever moving parts I can see without success
any chance you can take a picture of the area inside and post a picture by using the attach feature in chat? You should see a paper clip icon below that will let you attach pictures
