Contact-release solenoid off

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.
NOTE: 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 upon the following facts:
• The copier takes a shorter time to heat the hot roller when the roller is not turning.
• The temperature of the hot roller surface may become uneven when the hot roller
temperature is low and the roller is not turning.
