Paper conveying apparatus, jam detection method, and computer-readable, non-transitory medium

A method for determining a jam comprising;

• driving a moving member driven in relation to conveyance of a paper;
• acquiring a sound signal corresponding to a sound which a paper generates during conveyance;
• determining, by a computer, whether a jam has occurred based on the sound signal;
• and
• stopping conveyance of a paper when determining that a jam has occurred,
• wherein the computer controls so that the sound jam detector determines whether a jam has occurred by a determining method different from a determining method used while the drive module is not driving the moving member, or the sound jam detector does not determine whether a jam has occurred, while the drive module is driving the moving member, in the determining step.

A computer-readable, non-transitory medium storing a computer program, wherein the computer program causes a computer to execute a process, the process comprising:

• driving a moving member driven in relation to conveyance of a paper;
• acquiring a sound signal corresponding to a sound which a paper generates during conveyance;
• determining whether a jam has occurred based on the sound signal;
• and
• stopping conveyance of a paper when determining that a jam has occurred,
• wherein the computer controls so that the sound jam detector determines whether a jam has occurred by a determining method different from a determining method used while the drive module is not driving the moving member, or the sound jam detector does not determine whether a jam has occurred, while the drive module is driving the moving member, in the determining step.
