13. TRANSFER/TRANSPORT UNIT

13.1 General Description

The transfer/transport unit consists of the following 3 sections.
• Transfer section: Separates the paper from the drum with the transfer belt, and transports the paper
to the fuser unit.
• Fuser unit: Fuses the toner onto the paper.
• Horizontal transport section: Transports the reversed paper to the intermediate transport roller dur-
ing duplex printing.
The general descriptions of the transfer section and the horizontal transport section are shown below.
(The general description of the fuser unit is written in Chapter 14.)
Transfer section:
The paper transported from the registration roller and the toner on the drum are transferred to the trans-
fer belt by a static attraction (the paper is separated from the drum here), and then the separated paper
is transported to the fuser unit. The toner adhered on the transfer belt is cleaned in the belt cleaning
mechanism, and then transported to the used toner bag. The transfer section is driven by the transfer
belt motor (M14).
Horizontal transport section:
The reversed paper for duplex printing is transported to the horizontal transport section. At the horizon-
tal transport section, the paper is transported to the intermediate transport roller. The section includes 4
transport rollers controlled by 3 clutches (CLT1/2/3). The fuser motor (M3) drives the operation of this
section.
