2.4.1.1 Overview
LBP3100 / LBP3010B
The image formation system is the core of this equipment; it forms toner images on papers.
The image formation system is comprised of the following components.
The engine controller controls the laser scanner unit and high-voltage power supply circuit and forms images based on the video signals on papers.
The following are the details of print process for this equipment and the functions of image formation.
Fixing unit
Pressure roller

2.4.1.2 Print Process
LBP3100 / LBP3010B
This explains the basic process of the operations that a printer executes for image formation.
The print process of this equipment is divided largely into 5 blocks, 7 steps.
Toner images are formed on papers by executing the steps of each block in order.
The following are the blocks of print process and the steps.
1. Static latent image formation block
Step 1: Primary charging
Step2: Laser beam exposure
2. Development block
Step 3: Development
3. Transfer block
Step 4: Transfer
