Abstract

As sheet 10 is advanced in the direction of arrow 12 by endless belt conveyor 14, it engages actuator 16 of switch 18. Sheet 10 forces actuator 16 to pivot in a downwardly direction rotating magnet 20 to close the reed switch indicating the presence of a sheet of support material on belt 14, Belt 14 is entrained about a pair of opposed spaced rollers 22, one of which rotates to advance belt 14 in the direction of arrow 12. After sheet 10 passes over actuator 16, magnet 20 pivots to the opened position indicating the absence of sheet 10 on belt 14. Switch 18 is periodically interrogated to determine if it remains in the closed position beyond a preselected time duration, indicating a sheet jam.

As sheet 10 is advanced in the direction of arrow 12 by
endless belt conveyor 14, it engages actuator 16 of
switch 18. Sheet 10 forces actuator 16 to pivot in a
downwardly direction rotating magnet 20 to close the
reed switch indicating the presence of a sheet of
support material on belt 14, Belt 14 is entrained
about a pair of opposed spaced rollers 22, one of
which rotates to advance belt 14 in the direction of
arrow 12. After sheet 10 passes over actuator 16,
magnet 20 pivots to the opened position indicating
the absence of sheet 10 on belt 14. Switch 18 is
periodically interrogated to determine if it remains
