Paper Lift - Tray 2 (2)
Lifting stops when
the actuator leaves
the lift sensor
Lift Sensor
This is the same as the B234 series (Katana-C1).
The lift sensor detects when the paper stack is at the correct height.
As paper is used up, the lift sensor and lift motor keep the top of the stack at the
correct height for paper feed.
There is no paper height sensor in tray 2. However, the cpu calculates the
amount of remaining paper from the angle that the lift motor has turned (this is
explained again later in Remaining Paper Detection).
¾ Tray 1 has paper height sensors. These will be described later.
