Laser Beam

The printer has two interlock switches: the Front Cover Switch R and the Top Cover Switch. The purpose of these switches is to turn off the laser beam emission if any of t he pri nter cover s ha ve been op ened; this protects the user or service personnel from exposure to the laser beam from the ROS Assembly.

NOTE:The laser beam has a narrower frequency band and more

coherent phases than any other light (s unlight , electr ic light ). It has excellent monochromaticity and convergence. A thin laser beam reaches long distances. Because of its convergence characteristic, the laser beam converges into one point, causing high density and high temperature. A laser beam is harmful to the human body.

A laser beam may be emitted durin turn on these interlock switches simultaneously under any circumstances except in a normal operation.

W ARNING

Do not expose yourself to the laser beam to prevent injury (blindness).

Setup Menu

1. Standby Turns on/off the standby mode for saving energy while the p rinter is idle.

Enable: The standby mode is enabled. Disable: The standby mode is disabled.

When the standby mode is on, the printer enters the standby mode 1 or 2 according to the printer conditions listed below.

1) After emulation changeover, at least one printable images is completed.

2) Print request

3) Reset through the control panel

4) Warm-boot

5) “Standby” is set to “Disable”.

After any of the conditions above occurs, if a half of the specified time-out interval has passed without any occurrence of the conditions above, the printer enters the standby mode 1. While in this status, if any of the conditions above still does not occur within another half of the specified time-out interval, the standby mode 2 takes over. When any of the conditions above occurs, the energy save function is temporarily disabled (the printer returns to the normal standby mode or printing mode) to clear the total standby mode time to zero.

Standby mode 1

The printer uses less power than in the normal standby mode by controlling the fuser temperature within the specified range. This mode does not meet the energy-star requirement. Warm-up time (60 minutes to recover to the normal standby mode) is shorter than in standby mode 2.

Standby mode 2

The standby mode 2 keeps the Fuser Unit and the mechanism circuits turned off cons tantly and maximally, respectively, t o manage further energy save than the standby mode 1. This mode, complying with the energy star program (45 W or less), can minimize power consumption but requires approximately 3 00 seconds for warm-up time (standby mode 2

→ normal standby mode), which is longer than

standby mode 1.

NOTE: The remaining level of each toner is evaluated based on t he

dispense time of each toner cartridge. According to the dispense time, which is stored on the engine side, the engine generates such an error as “Toner Out”.

3. Total Pages Indicates the total number of sheets that the printer has printed on. (To be indicated only) Values within a range of 0 to 99999999 (increment: one page) are indic ated. The sheets ove r 99999999 are not counted. The printer shows the value counted on the engine side.

4. Color Pages Indicates the total number of color-print ing sheet s that the printer has printed. (To be indicated only) Values within a range of 0 to 99999999 (increment: one page) are indicated. The sheets over 99999999 are not counted. The printer shows the value counted on the controller side.

5. B/W Pages Indicates the total numbe r of B/W-printing sheets t hat the printer has printed. (To be indicated only) Since the value is a difference between the “Total Pages” and the “Color Pages”, if the total pages has exceeded 99999999, the indicated value is not correct. Values within a range of 0 to 99999999 (increment: one page) are indicated.

6. SelecType Init Clears the panel setting values to the factory setting values.

2.1 Print Process

2.1.1 Print Process Overview

This is a full-color laser printer using the Xerographic process. This process forms an image of toner (Yellow, Magenta, Cyan and Bl ack) on the surface of the drum. The image of one color is then transferred onto the IBT Belt Assembly (Belt). On the belt, this process is repeated four times, resulting in a full-color image. The print process is summarized as follows:

(1) Charge: Charges the drum surface. (2) Exposure: Exposes the image with a laser beam. (3) Development: Develops the image with the toner. (4) First transfer: Transfers the toner image on the drum to the

belt. (5) Cleaning: Cleans the drum. (6) Repeat: In the YMCBk mode, steps [1-5] are repeated

for each toner. At the end, the belt has a full-

color image. (The steps are not repeated in

the B/W mode.) (7) Second transfer: Transfers the image on the belt onto the

paper. (8) Detach: Removes the el ectrical charge from the paper. (9) Cleaning: Cleans the belt. (10) Fusing: Fixes the toner image to the paper by heat

and pressure.

drum rotation. The BCR is a conductive roll, receiving discharge voltage from the HVPS. The discharge voltage is negative DC voltage to which AC voltage has been superimposed. The discharge occurs in the very small gap between the BCR and the drum surface. The drum surface is uniformly charged (negative) with DC bias voltage. The drum surface consists of photoconductive material (on the surface) and an aluminum cylinder (inside the drum). (The photoconductive material becomes conductive when it receives light; it becomes an insulator in the dark.)

Figure 2-3. Charge

Chapter 2 Operating Principles 2-3

Page 67

EPSON ColorPage EPL-C8200 Revision A

2.1.3.2 (2) Exposure

In the exposure step, the system scans the drum surface (nega tively charged) with a laser beam and forms an invisible electrost atic latent image on the drum surface.



The printer controller outputs the data (image dat a) to the laser beam unit. As determined by the data from the printer controller, the laser beam unit emits a laser beam onto t he drum surface, the area of which is determined by data from the printer controll er. (That is, areas on the drum surface where the laser is emitted will be developed with toner; areas on the drum surface where the laser is not emitted will not be developed.) The laser beam is emitted from the laser diode in the ROS Assembly. The laser beam goes through the Scanner Assembly in the ROS Assembly, the rotating polygon mirror, fixed mirror and lens, and scans the drum surface from one end to the other in the axis direction of the drum.

The laser beam irradiated on the drum surface generates electronhole pairs in the photoconductive layer. (Excited electrons create a hole in the conductive band.) The electrons are attract ed by the electric field and move toward the inner conductor of the dr um and flow into it. The holes move toward the outside surface of the photoconductive layer and recombine with the negative charges (electrons) on the drum surface, thus decreasing the negative charges on the surface. The resultant l ess negatively char ged areas on the drum surface forms an invisible electrostati c latent image (printed image).

2.1.3.3 (3) Development

In the development step, toner particles are attracted to the invisible electrostatic latent image on the drum surface to form a visible toner image.



This printer employs the rotary and tr ickl e development methods. In rotary development, fo ur Dev elop er Ass embli es ro tate i n s equence; trickle development uses developer consisting of carrier and toner. The developer in the Developer Assembly is agitated by the Auger. (The auger is a spiral agitator.) The developer is sent to the Magnet Roll near the surface of the drum. The toner particles and carrier particles (that make up the developer) are charged by agitation; toner particles are negati vely charged, car rier particles ar e positively charged and thus electrically attracted each other. The carrier particles are magnetic and are attracted to the Magnet Roll (magnetized). The carrier particles go through the Trimmer Blade, resulting in a uniform carrier layer. The Magnet Roll surface is covered with a thin semiconductive sleeve. The HVPS applies the DB (Developing Bias) voltage to this sleeve. The DB voltage is negative DC voltage to which AC voltage has been superimposed. Using this DC voltage, the Magnet Roll retains constant negative voltage on the photoconductive layer of the drum. As a result, areas where negative potential on the drum surface has not been decreased have lower electric potential than the Magnet Roll; areas where negative potential has been decreased have higher electric potential. The AC voltage shakes developer onto the Magnet Roll so that it is easy for the toner particles to be attracted to the drum surface. The negatively charged toner particles are attracted only toward areas where negative potential on the drum surface has decreased, thus forming a toner image on the drum surface. When the toner particles adhere to the drum surface, the negative potential at that area where the toner particles are a dhering decreases, resul ting in a decrease in force in attracting toner particles to that area.



As the printer prints more pages, the toner i n the developer decreases. To maintain proper developer densi ty, it is necessary to resupply toner to the Developer Asse mbly from the Toner Cartr idge. This is called ‘Toner Dispensing.’ The Toner Dispensing mechanism uses two types of controls (PCDC and ADC). For details on PCDC and ADC, See Section 2.7.5.



To obtain a full-color image (of 4-color toner), four toner images (YMCBk) must be formed on the drum’s surface in sequence. This printer uses the rotary development method to form images. The rotary development method uses the Rotary Frame Assembly. The Rotary Frame Assembly has four Developer Assemblies which are installed every 90° (see figure below). For each image, the appropriate Develop Assembly faces the drum surface to for m an image. (For more details, see Section 2.7.7.)



The carrier looses its electrical charges. This occurs because the surface of a carrier particle may be covered with a toner particle or may be damaged by agitation. To maintain the electrical charge of carrier particles, a small amount of carrier is mixed in the toner; when the toner is dispensed, carrier is also supplied. The carrier in the Developer Assembly, however, is collected i n to a different chamber in the Toner Cartridge, so that the developer (mostly carrier) is replaced lit tle by little, resulting in a constant electrical charge being maintained. This is call ed the trickle development method. The trickle development method uses the rotation of the Rotary Frame Assembly. The trickle development process is as follows:

1. An L-shaped pipe is inserted in the developer.

2. A small amount of carrier moves into the pipe.

3. The carrier is sucked in and moves deeper into the pipe.

4. The carrier is collected in the Toner Cartridge.

2.1.3.4 (4) First Transfer (Drum → Belt)

In the first transfer step, the toner image formed on the drum surface is transferred onto the belt (Tr ansfer As sembly ) by th e 1st BTR (F irst Bias Transfer Roll).



The 1st BTR is a conductive roll, receiving positive high voltage from the HVPS. The 1st BTR touches the back of the belt. Following the rotation of the belt, the 1st BTR gives a positive charge to the back of the belt. The toner image on the drum surface (negatively charged) is attracted to the positive charge on the back of the belt. The image is transferred from the drum surface to the belt.

2.1.3.5 (5) Cleaning (Drum)

In the Cleaning (Drum) step, the residual toner on the dr um surface is scraped off and the residual charge is cleaned off.



Physical drum cleaning Toner that is not transferred in the 1st Transfer step remains on the drum surface. This residual toner is scraped of f by the Cleaning Blade. It is then tr ansport ed to the Waste Toner Box by t he Aug er in the Drum Cartridge.

Electrical drum cleaning An electrical charge still remains on the drum surface after the residual toner has been scraped off. This residual electrical charge is removed by the LED beam output from the Erase Lamp Assembly.

2.1.3.6 (6) Repeat (Forming a complete full-co lor toner image)

In the Repeat step (forming a complete full-color ton er image), the toner image of each color on the drum sur face is tr ansferred on to the belt and is repeated four times, resulting in a complet e full-color toner image on the belt.

Figure 2-11. Repeat (1)

EPSON ColorPage EPL-C8200 Revision A

2.1.3.7 (7) Second Transfer (Belt → Paper)

In the Second Transfer step, the complete image on the belt is transferred onto the paper. This is done by supplying voltage to the Contact Roll, Back Up Roll and 2nd BTR (Second Bias Transfer Roll).



The Contact Roll is a small-diameter metal roll and is in contact with the Back Up Roll. The Back Up Roll is a conductive roll and is in contact with the back of the belt. It faces the 2nd BTR where the bel t is in between. The 2nd BTR is also a conductive roll and is grounded to the frame via the metal shaft in the center.



The Contact Roll receives n egative high voltage (DC) and gives the potential to the Back Up Roll. The negative potential given to the Back Up Roll neutralizes the positive charge on the back of the belt, and induces a positive charge on the 2nd BTR through the belt and the paper. The Back Up Roll , belt and 2nd BTR have resi stance an d the paper functions as a capacitor, resulting in induction of a positive charge on the 2nd BTR. When the back of the belt i s neutrali zed, the be lt looses the abi lity t o retain toner and the complete toner image on the belt i s tr ansferred onto the paper by the positive charge induced on the 2nd BTR.



The paper (adhering to the belt) is transferred at the correct time so that the complete toner i mage on the bel t will be tran sferred ont o the paper in the proper position. When the paper reaches the point the 2nd BTR and the Back Up Roll face each other, the HVPS outputs high voltage.

Figure 2-13. Second Transfer (1)

Chapter 2 Operating Principles 2-11

Page 75

EPSON ColorPage EPL-C8200 Revision A



In the Repeat step (forming a complete full-color toner image), the toner image is transferred onto the belt from the drum surface four times. If, during these transfers, the 2nd BTR is touching the belt, the toner image created up to this point will be destr oyed. This means the 2nd BTR must touch (advance to) the belt only after the complete toner image has been transf err ed onto t he pap er. At other times, the 2nd BTR must be retracted from the belt. This Advance/ Retract switching operat ion i s ca rried out by the BTR Cam Solenoid .

2.1.3.8 (8) Detach

In the detach step, the charge on the paper is neu tralized/removed. Thi s is done when the Detach Saw gives negative DC voltage to the back side of the paper.



The Detach Saw receives high voltage from the HVPS. In the 2nd Transfer step, if there is a positive charge, the toner may scatter, resulting in a damaged image. To prevent this, the Detach Saw removes the charge on the paper.

2.1.3.9 (9) Cleaning (Belt)

In the Cleaning (Belt) step, the belt is clea ned aft er the image has been transferred onto the paper.



The belt has residual toner that was not transf erred onto the paper in the 2nd Transfer step. The residual toner is scraped off by the Cleaning Blade (in the Belt Cleaner Assembly) which i s touching the belt. The scraped toner is transferred through the Auger High Assembly to the Waste Toner Box.



In the Repeat step (forming a complete full-color toner image), the toner images are transferred from the drum surface to the belt four times. If, during these transfers, the Cleaning Blade is touching the belt, the toner image created up to this point will be destr o yed. So the Cleaning Bade must touch (advance to) the belt only after the complete image has been transferred onto the paper. At other times, the Cleaning Blade must be retracted from the belt. Thi s Advance/Retreat switching operation is carried out by the Cleaner Cam Solenoid.

2.1.3.10 (10) Fusing

In the Fusing step, the toner (image) is fused onto the paper by heat and pressure.



The complete full-color toner image transferred o nto the paper form the belt is very fragile, so it must be fused onto the paper by the Fuser Assembly. The toner is melted with heat from the Heat Roll and fused under pressure between the Pressure Roll and the Heat Roll. (The Heat Roll is heated by the H/R Heater.) As auxiliary heat, the Pressure Roll has a P/R Heater.



When the toner image is fused, the toner becomes adhesive, causing the paper to adhere to the Heat Roll. To prevent this, the Oil Roll Assembly supplies Fuser Oil to the Heat Roll. This allows the paper to be peeled off easily from the Heat Roll.



If the Oil Roll (Oil Roll Assembly) is continuously touching the Heat Roll, the Fuser Oil may degrade or cause oil spots on the paper. To prevent this, the Oil Roll touches (advances) the Heat Rol l onl y when the toner is fused; at other times it is retracted from the Heat Roll. This Advance/Retract switching operation is carried out by the Oil Cam Solenoid.

2.2 Print Data Flow

2.2.1 Data Flow

The print data (electrical signal s) from the printer controller goes through the processes shown below to form a final print image on the paper.

(Laser beam)

(On Drum) (Invisib le )

(On Drum) (Visible)

(On Belt)

NOTE:How a two-dimensional image is formed

Scanning the laser beam over the drum’s surface from one side to the other by switching the laser beam ON and OFF produces a dot image of one line. A single-color, two-dimensional dot image is produced by repeating the scanning of the laser beam for one page. To obtain a full-color image, a single-color image is generated for each color (YMCBk).

The resolution is determined by the following two factors:

- Main scanning direction: Dots/inch

- Subscanning direction: Number of scanned lines/inch

2.5.1 Paper Tray

1. Universal Tray



The End Guide can be moved toward the paper feed and holds the paper stack in place. By moving the End Guide, the moving force is transmitted to the Sector Gear and the position of the Tray Size Actuator changes. The Tray Size Actuator pushe s down (turns on) the Paper Size Switches (on the Size Switch Assembly). If the Tray Size Actuator position changes, the combinations of ON/OFF of the four Paper Size Switches change. The printer recog nizes the paper size from the ON/OFF combinations.



The Rear Guide Assembly moves in a direct ion perpendi cular to the direction of the paper feed and holds the paper stack horizontally.



The Bottom Plate Assembly pushes the paper stack onto the Feed Roll so that one sheet is pulled out by friction. The Tray N/ F Springs push up the Bottom Plate Assembly.



The bottom of the Bottom Plate Assembly has a magnet that detects the low paper state (Low Paper Sensor).



The Front Snubber pushes down a corner of the paper so that only one sheet of paper is pul led out. (Thi s mechanism us es t he stiffness of the paper to prevent more than one sheet of paper from being pulled out.)

Figure 2-26. Paper Tray

Chapter 2 Operating Principles 2-22

Page 86

EPSON ColorPage EPL-C8200 Revision A

2.5.2 Paper Feeder

1. Size Switch Assembly The Size Switch Assembly consists of four Paper Size Switches. (The switches are directly mounted on the circuit board.) When the Tray Size Actuator position changes, the ON/OFF combinations of these switches change and the printer detects the paper size and the paper tray.

2. Tray No Paper Sensor From the Tray N/P Actuator posit ion, the printe r detects paper in t he paper tray.

3. Low Paper Sensor If the paper in the paper tray gets low, the dist ance between the Bottom Plate Assembly and the Low Paper Sensor is shortened. That is, the Magnet behind the Bottom Plate Assembly gets closer; the Low Paper Sensor detects the magnetism from the Magnet, determining that the supply of paper is getting low.

4. Feed Solenoid By controlling the rotation of the Feed Gear, the operation (rotation/ stop) of the Feed Roll Assembly is controlled.

5. Feed Roll Assembly When the Feed Solenoid is act ivated, the Feed Spring f orc e caus es the Feed Gear and Feed Idler Gear to mesh. The Feed Roll Assembly then receives the driving force from the P/H Motor Assembly and starts rotating, causing the Feed Roll to pull a sheet of paper from the Paper Tray. The Feed Gear has a notch that, after it rotates once, dislodges the Feed Gear and the Feed Idler, causing the Feed Roll Assembly to stop rotating. This mechanism ensures that only one sheet of p aper is pulled out.

6. Turn Roll Assembly The Turn Roll Assembly receives the driving force fr om the P/H Motor Assembly (via the Main P/H Assembly); it rotates and sends the paper pulled out from the Paper Tray to the Main P/H Assembly.

2.5.3 Multi Sheet Inserter (MSI)

1. MSI Assembly The MSI Assembly feeds paper from the MSI Tray. The MSI Assembly consists of the MSI Edge Sensor, Pick Up Solenoid, MSI Clutch and others.

(a) MSI Edge Sensor

The MSI Edge Sensor detects the paper interval (from the bottom edge of the preceding sheet to the top edge of the next sheet) in the 2UP mode. I f the paper i nterval is too short, printing is not done properly in the 2UP mode. If the paper interval detected by the MSI Edge Sensor is shorter than the predetermined interval, the system tur ns off the MSI Clutch. This causes temporarily cuts the driving for ce to the Pick Up Roll s so that the paper transportation timing is adjusted.

(b) Pick Up Solenoid

The MSI Roll Assembly operation (r otat ion/s top) i s contr oll ed by controlling the rotation of the Pick Up Cam Gear.

(d) MSI Short N/P Sensor

When the MSI N/P Actuator position changes, the MSI Short N/ P Sensor detects paper on the MSI Assembly. The MSI Short N/ P Sensor only functions when the printer controller sends a signal indicating short paper size (shorter than 150mm) in the feeding direction.

(e) MSI Long N/P Sensor

The MSI Long N/P Sensor detects paper on the MSI Assembly by detecting the light reflected from the paper’s surf ace. The sensor is horizontally attached to the MSI Tray Assembly . It can detect light from the light emitter which is reflected on the paper’s surface. (A transparent OHP sheet can be detected by this method.) The sensor only functions when the printer controller sends a signal indicating long paper size (150mm or longer) in the feeding direction.

(g) Retard Pad Assembly

When the Pick Up Roll pulls out a sheet of paper, the friction between the paper and the Retard Pad Assembly prevents more than one sheet of paper from being pulled out.

If the paper interval detected by the MSI Edge Sensor is shorter than the predetermined interval, the paper transportation timing needs to be adjusted. If the paper interval is too short, the MSI Clutch temporarily cuts off the driving force to the Pick Up Rolls transportation timing. (to adjust the paper interval) and corrects the paper.

(h) Pick Up Roll

The MSI Roll Assembly receives the force from the Pick Up Solenoid and the MSI Clutch and starts ro tat ing and t he Pick Up Roll pulls out a sheet of paper. Both the Pick Up Gear and the Pick Up Cam Gear have a notch that, after rotating once, disengages the Pick Up Cam Gear and MSI Gear, thus causing the MSI Roll Assembly to stop rotating. This mechanism ensures that only one sheet of paper is pulled out.

Registration Rubber Roll

(a) The Registration Metal Roll and Registration Rubber Roll pull

out the paper in synchronization with the IBT Belt Assembly timing so that the paper will be positioned properly for the complete toner image on the IBT Belt Assembly to be correctly transferred onto the paper.

(b) Pre-Registration Roll Assembly transfers paper from the paper

tray or the MSI Assembly onto the Registration Metal Roll and Registration Rubber Roll. Until the top of the paper reaches the Registration Metal Roll and Registration Rubber Roll and until those rolls start rotating, the Pre-Registration Roll Assembly keep transferring the rear part of the paper by making a paper loop and correcting the skew at the top of the paper.

Registration Metal Roll. When the top of the paper reaches the Registration Metal Roll and Registration Rubber Roll it forms a loop. However, hard

paper (such as an OHP sheet) may go through the Registration Metal Roll and the Registration Rubber Roll without mak ing a loop. By turning on the Registration Brake Clutch , the Registration Metal Roll and the Registration Rubber Roll are constricted and the paper cannot go through—and that causes a paper loop.

(d) The Registration Clutch transmits the driving force from the P/H

Motor Assembly to the Registration Metal Roll and Registrat ion Rubber Roll so that the paper and the IBT Belt Assembly are properly positioned for a secondary image transf er.

(e) The Pre-Registration Clutch transmits the driving force from the

P/H Motor Assembly to the Pre-Registration Roll Assembly.

(f) The Registration Sensor detects when the top of the paper has

reached the Registration Metal Roll and the Registration Rubbe r Roll. To determine the paper size, the system detects the bottom edge of the paper. (The paper size is determined by the system keeping track of the time from when the Registration Clutch is turned on to when the Registration Sensor detects no paper.)

(g) The printer detects the front and back of an OHP sheet* fro m the

combined results of the Front OHP Sensor and the Rear OHP Sensor. (For more details, see “7.3 OHP Side Detection Control ” in Section 10.)

*The printer can use EPSON Color Laser Transparencies (S041175, S041174) only.

(h) The resistor and the capacitor installed on the front of the Main

P/H Assembly maintain the potential of the Registra tion Metal Roll at the time of image transfe r. If the Registr ation Metal Roll i s directly grounded, the potential of th e pape r escapes to the ground via the Registration Metal Roll. This means that the paper will not have enough potential for an image to be transferred correctly.

2.5.5 Xerographics I

1. ROS Assembly The ROS (Raster Output Scanner) Assembly outputs laser beam to form an electrostatic latent image on the drum’s surface. The ROS Assembly consists of the following components.



LD Assembly



Scanner Assembly



SOS PWB

(a) The image data is sent to the ROS Assembly as electrical

signals. (High and low voltage indicates dat a in the el ectrical signals.). The LD (Las er Diode) Assembly converts the electrical signals (of the image data) to optical signals (laser beam ON/ OFF). If the laser light quantity changes, a proper el ectrostatic latent image cannot be obtained. To obtain a stable laser amount, the LD Assembly (monitor circuit) always monitors and controls the LD output (LD Power). This is called the APC (Auto Power Control). For details, see Section 2.7. 4.2.

(b) The Scanner Assembly consists of the Scanner Motor and

Polygon Mirror. (The Scanner Motor rotates at a constant rotational speed; the Polygon Mirror is on the ro tational axis of the Scanner Motor.). The laser beam output from the LD Assembly is projected onto the Polygon Mirror. The Polygon Mirror has 12 reflecting surfaces; as the Scanner Motor rotates, the reflection angle of the laser beam changes. This change causes the laser beam to scan the drum’s surface in the drum axis direction. One reflecting surface of the mirror scans one line.

  

Lens Mirror Window

(d) To form a proper electrosta tic latent image on the drum sur face ,

the laser scanning timing and the writing timing of the i ma ge data must be coordinated. The SOS Sensor on the SOS PWB (Start Of Scan Printed Wiring Board) converts the laser beam into electrical signals ( SOS signals) which detect the initial position (scan start position) in each line that the laser will scan.

2.5.6 Xerographics II

1. Drum Cartridge The Drum Cartridge consists of the Xero. Cartridge, Waste Toner Box and others.

(a) The Xero. Cartridge consists of the Drum, BCR, Cleaning Blade,

and others.

• The Drum is an aluminium cylinder on which the OPC (Organic Photoconductor) material has been painted. The OPC material is photoconductive so a laser scanning the drum’s surface forms an electrostatic latent image on the drum. (Photoconductive: A photoconductive material is an insulator (holds potential in the dark) that, when it receives light, becomes conductive and the potential is grounded.)

• The BCR uniformly charges the drum surface in the Charge step in the print process.

• The Cleaning Blade scrapes off the residual t oner particles in the First transfer process in the print proces s.

(b) The Waste Toner Box collects the toner scraped off the drum’s

surface by the Cleaning Blade and the other toner sent by the Auger High Assembly (the toner scraped off from the IBT Belt Assembly by the Belt Cleaner Assembly).

5. ADC Sensor Assembly The ADC Sensor Assembly consists of the ADC Sensor, ADC Solenoid and others.

(a) ADC Sensor

The ADC (Automatic Density Control) Sensor detects the toner density of the image on the drum’s surface or toner densi ty of the drum’s surface itself, and sends the density data to the Process Control Unit. (For more details, see Section 2.7.5.)

(b) ADC Solenoid

If the ADC Sensor light emitter or receptacle is dirty with toner , the sensor cannot detect the toner density of the image or the drum’s surface. So, the ADC Sensor light emitter and receptacle are cleaned by the cleaning lever when the ADC Solenoid is activated.

2. Erase Lamp Assembly The Erase Lamp Assembly emits a light onto the drum’s surface to remove the residual charges remaining from the previous Ch arge process.

3. Waste Toner Sensor The Waste Toner Sensor detects when the Waste Toner Box is full of discarded toner.

4. Toner Box Sensor The Toner Box Sensor detects the Waste Toner Box.

2.5.7 Development

1. Used Cartridge Sensor The Used Cartridge Sensor detects whether the toner car tr idge is new or used for the color in each toner cartridge. In the trickle development method, the used developer is collected in the collection chamber in th e Toner Cartridge. A reflection seal has been pasted on a wall inside the chamber; when collected and accumulated in the collection chamber, the used developer covers the reflection seal. The Used Cartridge Sensor is a reflection type photo sensor. If it detect s a refl ected l ight f rom the Toner Cart ri dges for each color, it determines that the used developer has not filled up the collection box, meaning that the Toner Cartridge is still new. If it does not detect a reflected light from the Toner Cartridge, the Toner Cartridge is old.

2. Cartridge Sensor The Cartridge Sensor is a reflection type photo sensor. It detects a reflection light from the Toner Cartridges. If it detects a reflected light, it determines that the Toner Cartridge has been mounted. If it does not detect a reflected light, it dete rmines that the Toner Cartridge has not been mounted.

(a) The three Augers in the Developer Assembly:

• Supplies toner from the Toner Cartridge to the Developer Assembly.

• Agitates the developer in the Developer Assembly.

• Supplies the developer from the Developer Assembly to the Magnet Roll.

(b) The Magnet Roll has the following functions:

• Attracts the carrier particles.

• Forms an even developer layer.

• Supplies toner to the drum.

between the Magnet Roll and the Trimmer Blade; it forms an even developer layer on the Magnet Roll.

(d) The Tracking Roll maintains a gap between the drum and the

Magnet Roll.

5. The Toner Cartridges (Y, M, C and Bk) have toner (including carriers) and collect the used developer (carriers).

3. Rotary Sensor The Rotary Sensor detects the home position of the Rotary Frame Assembly. The Developer control is done based on the home position. (For more details, see “7.8 Developer Control.”)

4. Developer Assembly Y, Developer Assembly M, Developer Assembly C, Developer Assembly Bk The major components of each of these Developer Assemblies (Y, M, C and Bk) are the Augers, Magnet Roll, Trimmer Blade and Tracking Roll.

2nd BTR. (The IBT Belt Assembly is in the middle). When the paper passes through, the Back Up Roll provides the 2nd transfer voltage to the paper from the inside of the IBT Belt Assembly.

(d) The IBT Drive Roll Assembly transfers the driving force of the

Process Motor Assembly to the IBT Belt Assembly. (The Process Motor Assembly receives the driving force from the Process WDD Assembly.)

Process Motor runs, the transfer ref erence marks are alt ernately detected. This prevents the image from being transf erred onto the same location on the belt all the time—something that leads to image degradation.

(f) A one-color toner image on the drum is transferred onto the I B T

Belt Assembly. This process is repeated four times (for four colors). At the end, a 4-color overlaid toner image has been formed on the IBT Belt Assembly. When the complete toner image is formed on the belt, the 2nd BTR provides negative transfer voltage to the belt and the bel t tr ansfers t he image (of 4color toner) onto the paper (2nd transfer).

(e) The silver marks (TRO marks) is pasted at the rear end of the

IBT Belt Assembly. This is because t he toner images transfer red onto the IBT Belt Assembly must match precisely. The TRO Sensor detects this mark every time the IBT Belt Assembly makes one rotation. When the sensor detects the mark, the system waits for a predetermined period and then generates a TRO signal (which indicates the reference point and the image transfer reference point to form an image.) The IBT Belt Assembly has two TRO marks. As a result, every time the

2.5.10 Fusing-I

1. Fuser Assembly The Fuser Assembly fuses the toner on the paper with heat and pressure, and transfers the paper in and out, to and from the Fuser Assembly. The Fuser Assembly consists of the Main Fuser Assembly and the Fuser Tray Assembly.



Main Fuser Assembly The Main Fuser Assembly consists of the Heat Roll, Pressure Roll, H/R Heater, P/R Heater, Temperature Sensor Assembly and others.

• The Heat Roll is a cylindrical metal roll with a rubber layer on the surface. It applies heat to the paper to fuse the toner onto the paper.

• The Pressure Roll is a cylindrical metal roll with the rubber layer on the surface. It applies heat and pressure on the paper to fuse the toner on the paper.

• The H/R Heater is a halogen lamp in which hea ting coils have been sealed. (The heating coils provide the heat source for the Heat Roll.) The H/R Heater is installed inside the Heat Roll and heats the Heat Roll to the fusing temperature.

• The P/R Heater is a halogen lamp in which heating coils h ave been sealed. (The heating coils provide the heat source for the Pressure Roll.) The P/R Heater is installed inside the Pressure Roll and heats the Pressure Roll to the fusing temperature.

• The Temperature Sensor Assembly is a thermistor sensor. It always touches the Heat Roll and detects the temperature on the Heat Roll’s surface. (A thermi stor is an element that changes its resistance by temperature. ) From the detected temperature, the Temperature Sensor Assembly controls the ON/OFF of the H/R Heater and P/R Heater and prevents overheating (primary overheating prevention mechanism).

• The Thermostat is connected (in series) to the power supply circuits of the H/R Heater an d P/R Heat er. If the primary overheating prevention mechanism of the Temperature Sensor

Assembly fails, the contact point in the Thermostat opens, shutting off the power supply to the H/R Heater and P/R Heater (secondary overheating prevention mechanism).

• The Thermal Fuse is connected in series to the power supply circuits of the H/R Heater and P/R Heater. If the primary and secondary overheating prevention mec hanisms fai l, t he Thermal Fuse is melted by t he heat, shutting off the power supply to the H/R Heater and P/R Heater (tertiary overheating prevention mechanism).

• The Fuser Exit Sensor detects a paper pass from the position change of the Fuser Exit Actuator.

• The H/R Finger prevents paper from being rolled into the Heat Roll.

• The P/R Finger prevents paper from being rolled into the Pressure Roll.

2.5.11 Fusing-II

1. Fuser Assembly The Fuser Assembly fuses the toner on the paper with heat and pressure and transfers the paper to and from the Fuser Assembly. The Fuser Assembly consists of the Main Fuser Assembly and Fuser Tray Assembly.

(a) Fuser Tray Assembly

The Fuser Tray Assembly consists of the Fuser In Sensor, the Oil Cam Solenoid and the Exchange Solenoid. It transfers the paper to and from the Main Fuser Assembly.

• Fuser In Sensor The Fuser In Sensor detects a paper pass status from the position change of the Fuser In Actuator . (It detects the paper tip based on the detection timing of the Fuser Exit Sensor.)

• Fuser Chute Fan The Fuser Chute Fan pulls down the paper to the Fuser Paper Guide and the Horizontal Chute. This is necessary to position the paper correctly so that the paper is properly transferred to the Fuser Main Assembly.

• Cleaner Cam Solenoid The Cleaner Blade in the Belt Cleaner Assembly needs to touch the IBT Belt Assembly only immediately after the 2nd toner transfer. It must not touch the belt at any other time. (If the Cleaning Blade is touching the IBT Belt Assembly while the toner image is being formed on the IBT Belt Assembly, the toner image is damaged.) The Cleaner Cam Solenoid transfers the driving force from the P/H Main Assembly, via the P/H Drive Assembly, to the Cleaner Cam Assembly and the Cleaner Cam Guide, and controls the advance/retract operation of the Belt Cleaner Assembly. (Advance: The Cleaning Blade moves forward to the IBT Belt Assembly; Retract: The Cleaning Blade moves away from the IBT Belt Assembly.)

• O il Cam Solenoid If the Oil Roll in the Oil Roll Assembly is constantly touching the Heat Roll, the Fuser Oil may degrade and oil stains may

appear on the paper. The Oil Roll needs to touch the Heat Roll only during the fusing operation; at other times, the Oil Roll must remain separated from the Heat Roll. The Oil Cam Solenoid transfers the driving force from the P/H Main Assembly, via the P/H Drive Assembly, to the Oil Cam Assembly, and controls the advance/retract operations of the Oil Roll Assembly. (Advance: The Oil Roll of the Oil Roll Assembly moves forward to the Heat Roll; Retract: The Oil Roll moves away from the Heat Roll.)

• Exchange Solenoid After fusing, the paper may be ejected face up or face down. The Exchange Solenoid switches the Exchange Chute and controls the paper ejection modes.

• Exit-1 Roll Assembly The Exit-1 Roll Assembly transfers the fused paper from the Fuser Main Assembly.

2. Oil Roll Assembly The Oil Roll Assembly has an Oil Roll in which Fuser Oil has been impregnated. The Oil Roll in the Oil Roll Assembly follows the Heat Roll rotation and applies the Fuser Oil evenly onto the Heat Roll surface. The Fuser Oil prevents the following:

• Paper from being rolled into the Heat Roll.

• Heat Roll wear caused by contact with the Temperature Sensor Assembly and the H/R Fingers.
