ABSTRACT:
A paper feeding apparatus for a printer comprises a control means and a drive mechanism for feeding a sheet of paper to a predetermined printing position on the platen. The control means activates the drive mechanism for a predetermined period until a paper detective sensor near the platen detects a leading edge of the sheet. If the paper detective sensor detects no sheet after the predetermined period, a control means repeats the paper feed operation without requiring the operator to give a subsequent driving signal.
