(2) Image Transfer Corona
• The Image Transfer Corona, employing the corotron system, applies a DC positive
corona emission to the inside of the Transfer Film to attract the negatively charged toner
on the surface of the PC Drum onto the surface of the paper.
• Since image transfer takes places four times in the full color mode, the output from the
Image Transfer Corona is made higher each time than the preceding one.
• The corona output is varied according to the temperature and humidity inside the copier
and the type of paper being used.
• The corona output is controlled by High Voltage Unit 3 HV3.

(3) Charge Neutralizing Cloth

• An electric discharge occurs when the paper leaves the PC Drum after image transfer. At
this time, the positive charge on the surface of the Transfer Film is discharged onto the
PC Drum, disturbing the toner image on the paper. The Charge Neutralizing Cloth pre-
vents this from occurring.
