This printer is a "Full-color laser printer" which applies the principal of an electrophotographic recording system. The tandem system comprising a drum and developing unit respectively for each color of yellow, magenta, cyan and black (Y, M, C and K) places toner image of each color on paper producing full-color prints finally through 3 intermediate transfer units (IDT 1: 2, IDT 2: 1).

Printing processes of this printer is composed of the basic steps as follows.

1) Charging with electricity: Drum surface is charged with electricity.

2) Exposure: Image unit is exposed to laser beams.

3) Development: Image is developed with toner.

4) Primary transfer: Toner image is transferred to the intermediate transfer unit (IDT 1).

5) Secondary transfer: Toner image on the intermediate transfer (IDT 1) is transferred

to the intermediate transfer unit (IDT 2).

6) Cleaning: The intermediate transfer (IDT 1) is cleaned.

7) Tertiary transfer: Four-color finished toner image on the intermediate transfer unit

(IDT 2) is transferred onto the paper.

8) Cleaning: Intermediate transfer unit (IDT 2) is cleaned.

9) Static elimination: Electric charge of the paper is eliminated.

10) Fixing: Toner on the paper is fixed by heat and pressure.

11) Cleaning: Remaining toner on the drum and intermediate transfer units are

collected.

1.3 Description of Printing Process Techniques

1.3.1 Charging with electricity

In the charging process, the drum surface rotating at a constant speed is charged uniformly with negative electricity by discharging of HTC (Hechima Tube Charge: Charged film). This process is performed in parallel for yellow, magenta, cyan and black colors.

• The HTC is kept in contact with the drum and rotates following the rotations of the drum.

HTC is a conductive roll, receives discharge voltage from HVPS (High Volume Power Supply) and discharges at minus DC voltage.

• The drum surface is uniformly and negatively charged with DC bias voltage.

The drum surface is optical conductor (which is insulator in a dark place and conductor when receiving light) and the drum inside is composed of conductor.

• The Refresher is a conductive brush, and it receives negative DC voltage from the HVPS to catch the toner of reverse polarity returned to the drum via IDT. Also, it removes discharge products.

1.3.2 Exposure

In the exposure process, the drum surface charged negatively is scanned by laser beams to form invisible electrostatic latent image on the drum surface. This process is performed in parallel for yellow, magenta, cyan and black colors.

• Laser beams are emitted from the laser diode in the scanner ASSY. By the rotating polygon mirror, fixed mirror and lens attached to the scanner ASSY of the scanner ASSY, each color of drum surface is scanned from end to end in the axial direction.

• The laser beams are emitted based on the print data (image data) from the printer controller.

When the print data instructs to print pixel points, laser beams are generated and when the print data instructs not to print, no laser beams are generated. (On the areas which are developed by toner, the laser beams light up and areas which are not developed by toner, laser beams go out.) The laser beams emitted on the drum surface generate a pair (electron <=> hole) in the optical conductive layer. [Electrons are excited on the conductive zone, causing holes at the valence band.] Electrons are induced by the electric field, moved toward the inside metallic part and flow into it. The holes move toward the outer surface of the optical conductive layer, are combined with the minus charge (electron) on the outer surface again and decrease negative charge. As a result, on the drum surface where the electric potential increases, invisible static latent image (print image) is generated.

1.3.3 Development

In the development process, toner is electrically attached to the invisible statistic latent image on the drum surface to form visible toner image on the drum. This process is performed in parallel for yellow, magenta, cyan and black color respectively.

• The toner in the toner cartridge is agitated by the agitator in the toner cartridge and fed into the toner holder. Further, the toner is fed to the developer by the auger in the toner holder and the auger in the tube that connects the toner holder and the developer. The agitator and auger are spiral agitating components and they are driven by the toner motor provided on the rear of toner cartridge. The toner to be consumed according to the print count is calculated and fed into the developer. This is called "toner dispensation", which is controlled by two types of control, "PCDC" and "ADC". For the PCDC and ADC, see 7.4 Process Control in this chapter.

• The toner fed into the developer and the carrier in the developer are agitated by the auger, and supplied to the magnet roll arranged in the vicinity of the drum surface. The toner and carrier are charged by friction due to the agitation (toner in negative, carrier in positive), and they are absorbed each other electrically. As the carrier is a magnetic substance, it is attracted to the magnet roll having a magnetic force and a homogeneous layer is formed by the trimmer rod and the paddle.

• The magnet roll is covered by a thin semi-conductive sleeve over the surface. DB (Developing Bias) voltage is supplied to this semiconductor sleeve from HVPS. DB voltage is negative DC voltage combined with AC voltage. The magnet roll is kept at constant negative voltage against the optical conducting layer of the drum by DC voltage. Therefore, at the area on the drum surface where the negative electric charge does not decrease, potential is lower than the magnet roll, while the potential is higher than the magnet roll at the area where the negative charge on the drum surface decreases. The AC voltage shakes the developer on the magnet roll surface pressing the toner to fly to the drum.

Thus, the toner charged negatively is attracted only by the area where the minus

charge has decreased on the drum surface from the magnet roll (static latent image) and the toner image is formed on the drum.

When the toner is attached, minus charge at that portion increases, potential decreases, and force to attract the toner decreases.

1.3.4 Primary transfer (drum -> IDT 1)

In the primary transfer process, toner image formed on the drum surface is transferred onto the surface of the IDT 1 (Intermediate Drum Transfer 1: intermediate transfer roll 1). Two IDT 1 are provided: yellow and magenta, and cyan and black are respectively transferred to their IDT 1.

• IDT 1 is a conductive roll and receives supply of high positive voltage from HVPS. The toner image (negatively charged) on the drum is attracted to the IDT1 positively charged, and transferred from the drum to the IDT1 surface. At this time, electric charge of the drum surface is neutralized by the IDT1.

1.3.5 Secondary transfer (IDT 1 -> IDT 2)

In the secondary transfer process, the toner image formed on the IDT 1 surface is transferred onto the surface of the IDT 2 (Intermediate Drum Transfer 1: intermediate transfer roll 2). Two color toner image transferred onto the 2 IDT 1 is transferred to the IDT 2. Thus, 4 color toner image are compiled on the IDT 2 as finished toner image.

• IDT 2 is a conductive roll and receives supply of positive high voltage from HVPS. Both the IDT 1 and IDT 2 are positively charged. Voltage is higher on the IDT 2 and toner image is attracted to the IDT 2 surface and transferred onto the IDT 2.

1.3.6 Cleaning (IDT 1)

In the cleaning process (IDT 1), toner remaining on the IDT 1 after the toner image is transferred to the IDT 2 is temporarily stored in the IDT 1 cleaner.

• The IDT 1 cleaner receives positive high voltage from the HVPS with a conductive roll brush. The IDT 1 cleaner is placed in contact with the IDT 1 at the position through which it passes after the toner image having been transferred from the drum is transferred to the IDT 2. Toner remaining on the IDT 1 is electrically scraped and stored. The toner stored is collected upon completion of printing or at the time of cleaning cycle. (Refer to1.3.11 Cleaning (general).)

1.3.7 Tertiary transfer (IDT 2 - paper)

In the tertiary transfer process, finished toner image formed on the IDT 2 surface is transferred onto the paper under the voltage supplied to the transfer roll cartridge.

• Transfer roll cartridge is composed in the transfer roll cartridge ASSY. Transfer roll cartridge is a conductive roll and receives positive high current from HVPS. When paper passes through between IDT2 and transfer roll cartridge, plus potential is given to the back side of the paper so that the toner on the IDT 2 is transferred onto the paper. At this time, potential on the transfer roll cartridge is higher than that on the IDT 2.

1.3.8 Cleaning (IDT 2)

In the cleaning process, toner remaining on the IDT 2 after the toner image is transferred onto the paper is temporarily held at the IDT 2 cleaner.

• The IDT 2 cleaner is a conductive roll brush and receives positive high voltage from HVPS. The IDT 2 cleaner is placed in contact with the IDT 2 at a position through which it passes after the toner image having been transferred from IDT 1 is transferred onto the paper. Remaining toner on the IDT 2 is electrically scraped and held at the IDT 2 cleaner. The toner held is collected upon completion of printing or at the cleaning cycle. (Refer to 1.3.11 Cleaning (general).)

1.3.9 Static elimination

In the static elimination process, negative DC voltage is given to the back side of the paper from the detack saw (static elimination board) to neutralize and eliminate the charge of paper.

• The detack saw receives high voltage from HVPS. The positive charge caused in the tertiary transfer process generates image quality troubles by. scattering toner. Static electricity of the paper is eliminated by discharge of the detack saw preventing those image quality troubles.

1.3.10 Fixing

In the fixing process, toner is fixed on the paper by heat and pressure.

• Finished toner image transferred from the belt is easily broken only by touching it with fingers. The toner image is fixed on the paper with the fuser ASSY (fixing unit). The toner melts by heat of the heat roll with the heater lamp as the heat source and is deposited on the paper under pressure given by the belt opposed against the heat roll.

1.3.11 Cleaning (general)

In the cleaning (general) process, toner stored in the IDT 1 cleaner and IDT 2 cleaner after the finished toner image is transferred onto the paper and the toner remaining on the transfer roll cartridge are removed.

• The toner not completely transferred in the "secondary transfer" and "tertiary transfer" processes is held temporarily in the IDT1 cleaner and IDT2 cleaner. Also, the toner of which polarity is reversed and returned to the drum is held in the refresher. Further, the toner that passes the refresher may stick to the HTC.

These toners are cleaned at the completion of the printing. The recovery method is

different between the toner held in the IDT1 cleaner and IDT2 cleaner and the toner held in the refresher and HTC.

1) IDT1 cleaner and IDT2 cleaner High voltage equivalent to the voltage at the printing transfer is applied to the IDT1,

IDT2, and transfer roll cartridge. The toner (negative polarity) remaining in the IDT1 cleaner and IDT2 cleaner are moved to the IDT1 and IDT2 electrically by transforming the IDT1 cleaner and IDT2 cleaner to 0V. Then, in the same manner as in the printing transfer, the residual toner is collected to the transfer roll cartridge surface by potential difference between IDT1, IDT2, and transfer roll cartridge.

The toner (positive polarity) remaining in the Refresher and HTC are move to the drum electrically by transforming the Refresher and HTC to 0V. Then, in the same manner as in the printing transfer, the residual toner is collected to the transfer roll cartridge surface by potential difference between IDT1, IDT2, and transfer roll cartridge.

• Toner attached to the surface of transfer roll cartridge is scraper off with the transfer roll cartridge cleaner which is in contact with the transfer roll cartridge and collected into the collection space in the transfer roll cartridge unit ASSY.
