*1: For feeding speed, see 'Fixing Speed' under 'Controlling the Fixing Speed.'
The feeding speed of the pre-fixing feeding belt is changed as soon as paper has left the separation
sensor (PS15) and reaches the pre-fixing feeding belt. Thereafter, the speed returns to its initial speed when
the paper has left the internal delivery sensor (PS35).
The speed of the fixing roller, on the other hand, is changed as soon as the leading edge of paper
reaches the separation sensor (PS15); it returns to its initial speed as soon as the paper has left the internal
delivery sensor (PS35).
