Theory of Operation Ver. 1.0 Nov. 2005
C. Operation flow
1. The initial fusing speed is set to the low speed, thereby forming a loop in the paper
between the 2nd Transfer Roller and Fusing Rollers.
2. When the length of the loop formed in the paper becomes greater, the Fusing
Paper Loop Sensor (PS8) is activated (blocked).
3. While the Fusing Paper Loop Sensor (PS8) remains activated, the fusing speed is
kept at the high level.
4. When the Fusing Paper Loop Sensor (PS8) is deactivated, the fusing speed is
immediately switched to the low level.
5. The sequence of these operations is repeated so that the fusing speed is changed
automatically according to the loop length. This effectively makes for the difference
between the fusing speed and paper conveyance speed during image transfer.
