GP 15 Image Transfer
Overview
•
The toner image formed on the surface of the PC Drum during the developing process is
transferred onto the paper.
•
This printer adopts the roller image transfer system, in which the image transfer roller is used
to transfer the image onto the paper.
•
In the roller image transfer system, the paper is pinched between the PC Drum and the image
transfer roller at all times during the print cycle. This results in a very little amount of ozone
being produced and there is a little chance of a double transferred image occurring.
•
To clean the image transfer roller, reverse bias is applied to the image transfer roller.
•
The cleaning sequence is carried out when the printer is started, a print command is issued, a
print cycle is completed, and when the printer is started after a misfeed has been cleared.
•
There is the charge neutralizing needle installed for neutralizing the paper after image trans-
fer.
