Sharp AL1631 copier - line down center of copies made with toner residue
Hi there. Ok, open the door on the right side of the machine. You should see a unit and feel a lot of heat coming from it if the machine has been switched on. If you pull the black flap toward you it will reveal two rollers, a metal one (upper) and an orange one (lower). It's likely that one or both are damaged, this unit fixes toner to paper and if there is a scratch in the upper roller or a groove in the lower one, it will cause the symptom you describe. A qualified engineer could replace these though if you want to part with a bit more cash you may get a complete fuser unit for the machine which is relatively straight forward to change if your feeling adventurous.
Good luck

When I changed the drum
yes, this piece is from inside the drum unit. I just had the same issue, but luckily had another drum already for comparison from a different machine...

The U2-40 error can possibly be cleared. Press P, *, C, * to enter the service simulation. Enter 16 using the keypad, then the Copy Start button. Press Execute on the screen. Replace the toner cartridge if the error persists.

Paper jam
It sounds as if the paper is jamming in the fusing unit, which is where the heat roller melts the toner into the paper. This can be due to the heat roller starting to go bad. If it looks like there is toner build up on the roller, or if the teflon coating is starting to wear off, this will happen. Also make sure that the little fingers that ride on top of the heat roler, which prevents the paper from sticking to it, are seated correctly. The fusing unit may need to be replaced, or rebuilt.
