8.2.1.1 Controlling the Fixing Film Speed
0020-4141
The rotation cycle is measured with reference to the mark provided at the end of the fixing film to rotate the fixing drive motor at the optimum speed, thus keeping
the paper feed speed constant. Measurement of the cycle of each rotation (excluding the initial rotation and post-rotation) of the fixing drive motor starts when 1
second lapses after the motor starts rotating and ends when the trailing edge of the last sheet has passed through the fixing nipper.
