- 1. A printer with a sheet feeding apparatus comprising a printer body which incorporates a printing mechanism, a cutter which cuts continuous forms to a predetermined size, a sheet stacker which accommodates a stack of cut sheets, a sheet feeding path which is located between said sheet stacker and said cutter and which feeds said cut sheets at a rate higher than the feed rate of said printing mechanism, a sensor which detects the presence of said sheets in said sheet feeding path, a sheet length setting means which sets the length of each sheet to be cut, a time limiting means which sets an allowable time in which to detect a single sheet and another allowable time in which to detect a sheet-to-sheet interval, both time settings being based on the sheet length set by said sheet length setting means, and a judging means which compares the output of said time limiting means with that of said sensor to generate a judgment signal for indicating whether the sheet feed operation is normal or being jammed.
