Abstract:
1. A sheet finisher comprising: sheet stack forming means for sequentially stacking sheets to thereby form a sheet stack; cutting means comprising an edge for cutting the sheet stack at a preselected position; home position sensing means for sensing said edge brought to a home position; arrival position sensing means for sensing said edge has reached an arrival position remote from the home position; error detecting means for determining, when a preselected period of time elapses before said edge started moving from said home position reaches said arrival position, that an error has occurred; control means for displaying a message for a user to decide whether or not to continue a subsequent cutting job without cutting when said error detecting means has detected an error, wherein the control means proceeds with a subsequent job without cutting based on a user input to continue with the subsequent job; and guide means configured to move to a protruding position from the edge during sheet transporting and to move to a retracted position from the edge during sheet cutting, wherein the guide means moves to the protruding position after the edge cuts the sheet and returns to the home position.
