1103* Fusing Idling
This program decides the action of the Fusing Drive Release Mechanism (
6.13.2). When you select "1," the contact/release control is disabled and the drive
power is always transmitted to the fusing unit. As a result, the machine takes a
longer time to warm up the fusing unit. Use SP1-103-001 if fusing quality is low
even when the room temperature is not very low.
