Image Formation System

Overview

■
Overview
Toner image is formed by the magnetic, 1-component toner projection developing method in
image formation system.
To ensure high quality print, this machine introduces the following new technologies:
•
Small-diameter toner
High resolution by fine-grained toner
• Belt transfer method
Improved transfer/feeding performance by the belt feeding
•
Twin-developing method
Improving developing efficiency by the 2-time developing. Uneven developing at the first
developing is evened out with the second development.
At the second development, if toner is excessively supplied to the drum at the first
development, the excessive toner is pulled to the cylinder. If the amount of toner on the
drum is not enough, toner shortfall is supplied to the drum from the cylinder.
•
Image Stabilization Control
Image density/gradation correction by the D-max control and the D-half control
•
The shutter mechanism is added to the Primary Charging Assembly and the Pre-transfer
Charging Assembly.
This prevents discharge products from attaching on the Drum, thus prevents image failure
just after startup.
•
Improved accessibility to the periodically replaced / durable parts provides increased
serviceability.
