Pre-Transfer Led - KIP 9000 Service Manual

Pre-transfer LED

The potential of non-toner area of the Drum is -XV even after the Development process, which is
so high that the print media may not be separated smoothly from the Drum on later Separation
Process as it is strongly attracted to -XV area by the static force, and may result in a jam in the
worst case. To reduce the static force in advance before Separation Process, the Pre-transfer LED
throws light onto the Drum to remove the negative electric charges some degree from non-toner
area. The potential of non-toner area is increased from -XV to about -80V by Pre-Transfer Process.
