What is wrong with my printer?

Question

The cartridge speeds along to the right hand side slamming into the side hard enough to make the printer move.
It is a Lexmark Z735.
Started to happen after I changed the cartridge.

Answer 1

Is the cartridge the same type you had in there? If not you have the wrong cartridge, if so, make sure all the clips are in place. It might have been inserted wrong and needs to be readjusted.
