It rather sounds as if there may be some bits of paper left behind in
the printer.
You don't say what make the printer is. Many of them have a paper feed
button.
If your printer does, try pressing it with paper loaded as if for
printing. Does the
paper feed through? If not, the likelihood is that paper is still
jamming the roller
and you need to try to remove it. Incidentally, do not fiddle inside the
printer
internals with the power connected!
Let us know the make and model of the printer and someone may be able to
offer further advice.
