Image Transfer And Paper Separation - Ricoh D009 Service Manual

Image Transfer and Paper Separation

the transfer belt motor rotates half a complete rotation. The contact lever, riding on the cam,
is lifted up and the springs [E] push the belt into contact with the drum.
The transfer belt HP sensor [F] detects the home position of the cam (this is when the belt is
away from the drum). The belt must be released from the drum between copy jobs in order
to prevent the ID sensor pattern from being rubbed off and to prevent contamination of the
drum from the surface of the belt.
6.14.4 IMAGE TRANSFER AND PAPER SEPARATION
MECHANISM
When the paper enters the gap between the belt and the drum, the high voltage supply
board [A] applies a high positive current to the belt to transfer the image to the paper.
After receiving the image from the drum, the paper is fed by the belt. The paper moves to the
end of the transfer belt unit, where it separates from the belt as the belt curves away. Then
the paper moves on to the fusing unit.
