*This is the jam detection timing for the 1st bin.
Timing depends on the bins used.
– Sorter Jams –
The sorter stapler main control board detects jams when the following
conditions are detected. In these cases, a jam signal is sent to the copier,
then the copier stops the paper feed and indicates a sorter misfeed.
– Normal (Proof) mode –
J1: The entrance sensor has not turned on 700 ms after the copier exit
sensor turns on.
J2: The entrance sensor stays on for more than a certain number of pulses
(for example, 280 pulses for A4 sideways).
J3: The proof exit sensor has not turned on 300 pulses after the entrance
sensor turns on.
J4: The proof exit sensor stays on for more than a certain number of pulses
(for example, 280 pulses for A4 sideways).
– In Sort/Stack or Staple Mode –
J1 and J2: Same as Normal mode.
J5: The bin jam sensor has not turned on for 600 pulses after the entrance
sensor turns on.
J6: The bin jam sensor stays on for more than a certain number of pulses (for
example, 280 pulses for A4 sideways).
J7: The bin jam sensor is still on when the bin drive motor turns on.
