Paper is getting jamed as it attempts to enter the finishing unit.

must be fuser unit, look for these signs :
1- upper roller damaged
2- does not have a "polished " finish
3-lower roller has ripples /waves on it

Do NOT attempt to switch it on while disassembled! Put it back together and it will work if you cleared all stuck paper. There's bin sensor and feed sensor that activates the unit Be safe!

Well open the printer where you can(the closest point to the jammed paper) attempt to remove the jam by attempting to pull the Jamed paper in the direction it would normally exit the machine.thats about as far as I can get you with the information I have--Good Luck.

If the jam is consistent with exiting the drum, there's a chance the drum isn't secure and is the paper is getting caught on the exposed area of the drum. If this isn't the case, there may be paper caught in the feeder wheels.

Look where you remove the last jamed piece of paper closest to the fixing unit. Dose it jame when you make one copy? If it dose jam in the same place, I would have to say the problem is in the fixing unit. Look, in the unit for any pieces of paer jamed and remove them. Also, is it only happen with one paper tray and not the other. If so make sure you haze the tray and paper are set correctly.... Really need some more info.
