The light emitting from the LED Head will be exposed to the negative charged image drum. When the
surface electric potential of exposed part of the image drum goes to decrease, the electrostatic latent image complying with image signal is formed.
Image drum is coated by basic layer (UL), charge generating layer (CGL), charge transferring layer (CTL)
on the basic material aluminum. The thickness of the organic light sensor (OPC) that is consisted by CTL and CGL is approximate 20µm.

2. Operational explanation
fiction electricity occurs between the image developing roller and toner; toner is attracted to the image-developing roller.
2. The toner that has been attracted to the image-developing roller is dropped down to the developing plate to make a thin toner film on the image developing roller side.
3 The toner is attracted by the exposed part (Low electrical potential part) of the image drum
when the image drum contact the image developing roller, so as to see the electrostatic latent image.

2.2 Printing process
The paper fed from Tray 1 and Tray 2 is conveyed by feeding roller, conveying roller, and resist roller. When feeding paper is from MPT, it is conveyed by MPT, feeding roller, and resist roller. After that the feeding paper that is conveyed by image drum and the nip part of transfer roller forms toner image on the paper through electrophotographic process. And then, the toner on the paper is fused by the heat and pressure as the fuser unit passing through. The paper that fused the toner image is ejected from the face down stacker of the ejecting roller. In the case of face up ejecting, it needs to open the backside cover and install face up stacker. (It is unavailable for duplex printing while it is face up ejecting.)
The above is about the operations at simplex printing, yet the below explains the operations at duplex printing. While duplex printing, the paper, which firstly passed through the fuser unit after the backside printing, is conveyed to the inward of Duplex Unit, by the reverse operation of the second ejecting roller that is a certain time after removing the first ejecting roller of the paper rear side. Paper, is conveyed by conveying roller of Duplex Unit, and then merges to the same route with the feeding paper that is from
the tray. Onwards, it is the same with the simplex printing operation by the feeding paper from tray.

2.3 Toner entrance detection
• Equipment Toner entrance detecting equipment consists the agitating gear that agitating the agitating bar at a
certain speed and magnet that is on the agitating bar.
Operation Detecting the toner low by monitoring the congruous time intervals between the magnet that is set on
the sensor plate and the magnet attached on the agitating bar,
2. Operational explanation
Operation in toner full status
The crack part of agitating gear meshing with the
projection portion of agitating bar, the agitating bar rotates in accordance with the rotating of gear.
Even after the magnet part of the agitating Bar reaches
the highest position, it still rotates at the same speed by the pressure of the agitating gear due to the toner resistance.
Operation in toner low status
When the magnet part of the agitating bar reaches the
highest position, because there is no resistance from toner, the agitating bar drops earlier than the gear by the gravity itself, and stops by that status.
For this reason, the time that the magnet of agitating
Bar magnetic attracts the magnet of sensor plate becomes longer. The toner low status can be inspected
by monitoring this time.

Risk of Electric Shock
3. Parts replacement
There is a risk of electric shock during replacement of the low voltage power supply. Use insulating gloves or avoid direct contact with any conducting part of the power supply, and caution should be
exercised during replacement. The capacitor may take one minute to complete discharge after the AC cord is unplugged. Also, there is a possibility
that the capacitor doesn’t discharge because of a breakage of the PCB, etc., so remember the possibility of electric shock to avoid electric shock.
(b) Reconnecting the printer by the following procedures. i) Connect the AC cord and interface cable to the printer. ii) Connect earth wire to the AC socket. iii) Connect the AC insert plug to the AC socket. iv) Turn on the power switch of the printer. (

3.3.17 High voltage / Low voltage power board
There is a risk of electric shock during replacement of the low voltage power supply. Use insulating gloves or avoid direct contact with any conducting part of the power supply, and caution should be
exercised during replacement. The capacitor may take one minute to complete discharge after the AC cord is unplugged. Also, there is a possibility
that the capacitor doesn’t discharge because of a breakage of the PCB, etc., so remember the possibility of electric shock to avoid electric shock.
