8 Paper Discharging
The paper discharging process is where the transported paper onto which the toner
transfer has been completed is separated from the transfer drum by applying an AC
charge to the paper.
(1) Structure of Paper Discharger (Refer to Fig.4-22.)
i) The AC charger unit for discharge the paper is located as shown in Fig.4-8.
ii) The AC charger unit consists of the case and a charger wire.
iii) A high alternating voltage (VAC) is fed to the AC charger unit.
(2) Process of Paper Discharging (Refer to Fig.4-22.)
i) The paper adheres to the transfer drum in the transfer process.
ii) The paper is neutralized (discharged) in terms of any electrical charge by the
alternate voltage generated by the discharger.
iii) Paper is separated from the transfer drum and subsequently transported to the
fusing (fixing) process.
