ABSTRACT:
A sheet feeder feeds a continuous form in a reverse feeding direction to the normal feeding direction from a position detected by a first sheet sensor. A timer counts a predetermined interval until the continuous form is surely fed by the distance from the sensor to the exterior of the printer. An additional sensor, downstream of the first sheet sensor and close to the sheet outlet in the normal printing direction, is used with the timer and appropriate counting intervals to detect paper jams as the reversely fed continuous form passes through the printer. A controller stops the reverse feeding upon the detection of a jam, and displays a jam error message on a display provided to a control panel. The sheet feeder is alternatively a pair of rollers or a tractor unit.
