According to the paper interval with the previous paper, the
timing of speed reduction is varied to adjust the paper interval.
However, speed reduction must be completed before reaching

2. Paper empty detection
When the rotation plate lifts and stops at the paper feed enable
position, paper empty in the tray is detected during paper feed
operation by the paper empty detector (D1PED).
