Intermediate Transfer Unit

Function of the intermediate transfer unit

The intermediate transfer unit consists of the transfer belt, belt
cleanser and waster toner bottle in which cleaned toner is collected.

The transfer belt is made of an electrically conductive resin. The
toner image, when placed on the organic photoconductor (OPC)
drum is transferred onto the transfer belt by an electric field. The belt
makes four turns, so that four color toner images, yellow (Y),
magenta (M), cyan (C) and black (BK) are transferred onto the belt.
The color image is formed on the transfer belt and the entire image
is transferred onto paper by the transfer roller forming the color
image on the paper.

Note: While the four color toner images are still on the transfer belt
the transfer roller, discharge roller and cleaning roller are pulled
away from the transfer belt. An optical reflector is attached on one
edge of the outer circumference of the transfer belt and is used by
the home position sensor to detect the position of the belt. After the
image is transferred to the paper, any toner remaining on the belt is
cleaned by the cleaning roller and transferred through the transport
coil into the waste toner bottle in the belt unit. When cleaning the
remaining toner, after the image has been transferred to paper, the
transfer roller, discharge roller and cleaning roller, touch the transfer
belt.
