I realize english is not your first language, so I am trying to better
understand what you are asking. If you are having difficulty in writing
in english, or in understanding my reply, you can try using one of the
one line translators. Just cut and paste my response into it and it
will translate, or type your message and translate the other direction.
These translators do a good job.
This one is pretty good:

When you say that once you print a paper, the printer asks for another
paper, do you mean the first paper is printed on normally, and then the
printer asks for yet another page of paper, or are you saying that the
first paper is not printed on, and the printer asks for another paper
even though the first paper is not printed on?
This may be the paper transport is slipping, so the paper is not
advancing properly, and the paper sensor is indicating the paper isn't
there, or the paper sensor may have failed.
