(4)Transfer / Separation charger

(a)Transfer guide

This guide leads the paper transported from the feeding unit to the transfer section.

Positive (+) bias voltage is applied to the guide to prevent the transferability from being low- ered under conditions such as high humidity.

(b)Transfer charger

The transfer charger applies a charge (positive (+) charge) which is contrary to the charging polarity of the toner to the back of the paper. The toner image is transferred electrostatically on paper by performing this corona discharge.

(c)Separation charger

After the transfer process, the corona discharge applies a bipolar charge (AC) on the back of the paper to separate the paper adhering to the drum surface by an electrostatic force absorb- ing.

(5)Toner bag full detection sensor -2

This transmissive-type sensor detects the full of toner bag when the used toner has reached to the full detection position in the toner bag.

"Toner bag full" is determined when either of the toner bag full detection sensors-1 and -2 detects full of toner. Printing is interrupted upon the detection of "Toner bag full" status, however, the pa- per already fed is subject to be printed and exited.

Detecting with the toner bag full detection sensor-1 may cause the overload of the drum cleaning blade, and even the excessive toner may be fallen from the toner bag. The reason why the toner bag detection sensor-2 is installed is to detect full of toner prior to the occurrence of these prob- lems.

When the sensors are in trouble, "Toner bag full" is determined instead of "Call for service". If "Toner bag full" status is not cleared, the sensors, harnesses and LGC board need to be checked.

(6)Sub-separation fan / Exhaust fan

The sub-separation fan works to assist the separation of paper from the drum surface by absorb- ing the air from the back of the paper. The exhaust fan removes ozone generated by corona discharge with the ozone filter, and also cools down the inside of the equipment.
