I: Varied by value under ‘30’ of service mode (registration adjustment).
II: Used for measuring the length of copy paper.
length of copy paper (mm) = 96 (mm/s) × II (s) + 11 (mm) -10 (mm)
96 (mm/s): speed at which copy paper is moved.
11 (mm): distance between pre-registration roller paper sensor and registration roller.
10 (mm): length of actuator of the pre-registration roller paper sensor.
