The drum is made up of two distinct, semiconductive materials on an aluminum alloy base. The outer of the two layers is called the Charge Transport Layer (CTL), while the inner layer is called the Charge Generating Layer (CGL). The PC Drum has its grounding point inside at its rear end.

The grid voltage (VG) applied to the grid mesh is selected between -650V in the normal mode and -520V in the Photo mode by the ConstantVoltage Circuit in the High Voltage Unit. The Corona Unit has a Comb Electrode which minimizes the amount of ozone produced.

The image is enlarged or reduced as necessary by changing the position of the Lens and 4th Mirror and varying the angle of the 4th Mirror.

FrameMaker Ver.5.5(PC) EP1054/EP1085/EP2030 MECHANICAL/ELECTRICAL 98.04.24 1174SBM0901A 9-1. Exposure Lamp An AC halogen lamp is used as the Exposure Lamp. As the exposure level is adjusted on the control panel, the duty ratio of the pulse of AVR Remote from the Master Board changes to increase or decrease the Exposure Lamp voltage, thereby changing the image density. In Photo mode, the voltages are varied on a level 5V lower than the manual Exposure Lamp voltages.

FrameMaker Ver.5.5(PC) EP1054/EP1085/EP2030 GENERAL, MECHANICAL/ELECTRICAL 98.04.24 1174SBM0902A 9-2. AE Sensor In the Auto Exposure Mode, the AE Sensor on the AE Sensor Board measures the intensity of the light reflected off the original, which results in the black/white ratio of a 210-mm-wide area from the reference position of the original being measured. According to this measurement, the Exposure Lamp voltage is automatically increased or decreased so that copies of consistent quality are produced.

FrameMaker Ver.5.5(PC) EP1054/EP1085/EP2030 MECHANICAL/ELECTRICAL 98.04.24 1174SBM0903A 9-3. Lamp Reflectors The Main Reflector ensures that light from the Exposure Lamp exposes all areas of the original. The Auxiliary Reflector reflects light onto the areas that the Exposure Lamp cannot illuminate when an original that does not lie flat on the Original Glass (such as a book) is being used. This reduces shadows which would otherwise be transferred to the copy.

At the start of a scan motion and other heavy load conditions, the Scanner Motor requires a large amount of current. The Current 1 or 2 signal from the Motor Drive Board is selected accordingly to vary the amount of current supplied to the Scanner Motor. ✽ The Current signal selection timing is controlled by software.

FrameMaker Ver.5.5(PC) EP1054/EP1085/EP2030 GENERAL, MECHANICAL/ELECTRICAL 98.04.24 1174SBM1101A 11-1. ATDC Sensor The ATDC Sensor installed on the underside of the Developer Mixing Chamber detects the varying toner-to-carrier ratio of the developer which flows over it in the Chamber. The copier CPU compares the detected ratio with the ratio set by the ATDC Detection Level Mode (Tech. Rep. Choice C-90) to control toner replenishment. Set T/C (%) 6.0 ATDC Output Voltage (V) 2.

FrameMaker Ver.5.5(PC) EP1054/EP1085/EP2030 MECHANICAL/ELECTRICAL 98.04.24 Toner Empty Detection The copier has no toner empty detecting sensor and, instead, the ATDC Sensor performs that function. The ATDC Sensor checks the toner-to-carrier ratio and, if it reads a T/C ratio lower than the set level for 37 copies and, further, if it next reads a ratio 1% lower than the setting, this is a toner-empty condition.

Magnet Roller The Magnet Roller of the Sleeve/Magnet Roller of this copier has the following magnetic characteristics. Part of pole S2 before the principal N1 pole (i.e., the area marked as S2b in the Fig. below) provides a very weak magnetic force.

FrameMaker Ver.5.5(PC) EP1054/EP1085/EP2030 MECHANICAL/ELECTRICAL 98.04.24 1174SBM1103A 11-3. Developing Bias A negative voltage (Vb = Developing Bias voltage) is applied to the Sleeve Roller to prevent a foggy background on the copy. The amount of toner attracted onto the surface of the PC Drum depends on how much lower the PC Drum surface potential (Vi) is than Vb (i.e., the potential difference). • When the potential difference is large, a greater amount of toner is attracted.

Paper Separating Mechanism Each Drawer has Fingers that separate the top sheet of paper from the rest of the paper stack at paper take-up. The Fingers are fitted to the right front and rear corners of the Drawer. When the Paper Take-Up Roll starts turning to take up the top sheet of paper, its turning force is directly transmitted to the top sheet of paper as it is in direct contact with the Paper Take-Up Roll.
