Title:
AUTOMATIC JAM REMOVAL DEVICE
Document Type and Number:
Japanese Patent JPH0577500
Kind Code:
A
Abstract:
PURPOSE: To remove a jam at the time of paper feeding.
CONSTITUTION: A detection sensor 30 is disposed upstream of a printing part 18, and a detection sensor 28 is disposed downstream of the printing part 18. A feed roller PF2 is disposed between the printing part 18 and the detection sensor 30. A feed roller PF1 is disposed upstream of the detection sensor 30. On paper to be fed, marks 26 are equidistantly arranged at the same interval as a distance between the detection sensors 28, 30. If the detection sensor 28 fails to detect a mark while the upstream detection sensor 30 detects a mark 26, the feed roller PF1 is reversely rotated.
