Abstract
A system for indicating fault conditions in an automated banking machine includes a journal printer (12). The journal printer is supplied with paper from a paper supply roll (16). The paper supply roll is supported on a spindle (22). The spindle is engaged to the paper roll by spring arms (60). The spindle further includes a spring loaded retainer member (42) and a flange portion (34) which act to apply a drag force on the spindle to prevent overrunning. The spindle also has an encoder member (40) thereon. Rotation of the encoder member is sensed by an opto-electrical detector (70). A diameter of the paper supply roll is sensed by a second opto-electrical detector (78) positioned between the spindle and the printer. The detectors are connected to an electronic circuit (74) including a processor (76). Fault signals are generated by said electronic circuit responsive to said detectors sensing conditions representative of paper jam, paper low and paper out conditions.
