The ETB unit transfers toner into paper while feeding the paper.
The ETB unit consists of the ETB, ETB tension roller, ETB feed roller, ETB slave roller, attraction roller, and transfer roller.
The ETB motor (M5) rotates the ETB feed roller, and this drive rotates the ETB. All of other rollers are driven by the ETB.
At the time of printing, the fed paper is attracted to the ETB by the attraction roller, and transported according to the rotation of the ETB. During transportation,
toner is transferred by the photosensitive drum and transfer roller of each color. After the toner is transferred, the paper is separated from the ETB by the ETB feed
roller.
Especially at the time of color printing, high accuracy is requested for paper feeding by the ETB because one image is formed with four color toners overlapped.
The ETB is also used for image stabilization control. When image gradation corrective control or color displacement corrective control is executed, the pattern
image for color displacement or image gradation correction is written on the ETB.
The ETB unit executes the following three major controls.
- Automatic bias control
- ETB cleaning
- Transfer roller engagement/disengagement control
