NOTE: 1) P1-P4 represent the four positions on the width sensor board. ON
indicates the presence of the terminal plate in a given position. “Original
Width-1” and “Original Width-2” are the outputs from the sensor board to
the DF main board. The state of these outputs (L or H) depends on the
position of the terminal plate on the sensor board (P1, P2, P3, or P4).
For example, if the terminal plate is at P4, both outputs are L.
2) A reading of “L” on either of the width sensor outputs indicates that the
terminal plate is connecting the GND pattern with the width sensor
output signal line.
3) The machine cannot detect more than one size of originals in the same
job.
