Composition/Operation
11. Image transfer section
11.1 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
transfer.
