Hot Roller Drive
Left: Contact-release solenoid off
Right: Contact-release solenoid on
Mechanism
The main motor [A] drives the hot roller [D] through a gear train. One of the gears in the gear train is the
contact-release gear [B]. This gear is linked to the contact-release solenoid [C]. When the contact-release
solenoid is on, it separates the contact-release gear from another gear [E] in the gear train. As a result, the
drive power of the main motor is not transmitted to the hot roller.
The drive power of the main motor is not transmitted to the paper exit roller [F]. This roller is driven by the
duplex motor.
Contact/Release Control
The contact-release solenoid turns on when the following conditions are all met:
• The copier is warming up the hot roller.
• The hot roller temperature is 16°C or higher.
• The fusing idling (SP1-103-001) is “No.”
This control is based on the following facts:
