Description of Operations
Paper brought from the fuser unit to the bridge unit is then transported to either the upper or lower exit
tray of the paper exit unit by means of bridge unit transport rollers-1, -2 and -3, and bridge unit exit
rollers-1 and -2. To transport paper to the upper exit tray, transport path switching solenoids-1 (SOL1)
and -2 (SOL2) are turned ON in order to lower flappers-1 and -2. To transport it to the lower exit tray,
only transport path switching solenoid-1 (SOL1) is turned OFF in order not to lower flapper-1. The
paper transported from the bridge unit to the paper exit unit is then made to exit by the upper or lower
exit roller.
When the duplex printing mode is selected, first the print data of the back side of the original are printed
on the back side of the fed paper, and then the printed paper is transported from the fuser unit to the
bridge unit. At this time transport path switching solenoid-1 (SOL1) is turned ON in order to lower
flapper-1, and transport path switching solenoid-2 (SOL2) is turned OFF in order not to lower flapper-2,
so that the paper will be transported to the reverse path section. When the reverse sensor (S59) of the
bridge unit detects the trailing edge of the paper, the reverse roller is driven to switch back the paper to
the duplexing unit via the duplexing bridge unit. Then the print data of the front side of the original are
printed on the front side of the paper that was transported from the duplexing unit to the registration
section. After printing on the both sides of the paper is completed, the paper is made to exit by the
bridge unit and the paper exit unit.
Paper jams on the upper transport path are detected by means of the reverse sensor (S59) of the
bridge unit and the upper paper exit sensor (S61) of the paper exit unit. Paper jams on the lower
transport path are detected by means of the bridge unit path entrance sensor (S55), bridge unit path
exit sensor (S56) and lower paper exit sensor (S63). Paper jams on the reverse path are detected by
means of the reverse path sensor (S57). The reverse section stationary jam detection sensor (S58) of
the bridge unit and another reverse section stationary jam detection sensor (S60) of the paper exit unit
detect where the jammed paper lies on the reverse path.
