6. DRIVE SYSTEM

6.1 Construction of Drive System

The drive system drives the drum (cleaner unit), developer unit, transport belt, heat roller, exit roller,
transport roller, cassette feed roller and aligning roller.
The drive system is driven by the main motor, the aligning motor and the feed motor.

6.2 Description of Operations

• Drum drive .......................... Main motor rotation is transmitted to the drum drive pulley via the timing
(Cleaner unit)
• Developer unit drive ........... Main motor rotation is transmitted to the developer unit drive gear via
• Heat roller drive .................. Main motor rotation is transmitted to the heat roller gear via timing belt
• Transport belt ..................... Transport belt gear is driven by the heat roller gear via the idle gear.
• Exit roller ............................ Exit roller gear is driven by the heat roller gear via the idle gear.
• Aligning roller ..................... Aligning motor rotation is transmitted to the aligning roller via the timing
• Transport roller ................... Main motor rotation and feed motor rotation are transmitted to the trans-
• Cassette feed roller ............ Feed motor rotation is transmitted to the cassette feed roller via timing
