Selects the Paper Source that matches the specified Paper Size from the Paper Sources where the Paper Type specified by the mode matches the setting value for each tray as shown in the above table.

Paper Source = MP, LC1, LC2, LC3 :

Selects the specified Paper Source.

 Paper Type = Thick, ExtraThk, Trnsprnc, Coated :

The Paper Source always selects the MP Tray.

 Engine control

Engine control is performed giving priority to the Paper Type settings. When Paper Type is set to Normal, engine control is performed with the setting value of the selected tray. The Paper Type, that is determined when selecting Paper Source, is specified only by the ESC/Page, ESC/Page-Color or LJ4 commands. The Paper Type setting does not use Bond to avoid confusion with Thick.

1.14.6.3 Printing Menu

RITECH

This is an outline correction function which is equivalent to that of a monochrome page printer in B/W printing. In color printing, the outline correction function is accomplished by the CRIT function.

PAPER SOURCE

Selects the paper source when Paper Type = Normal.

Auto : Feeds paper from the paper source that loads paper of the specified

paper type and paper size.

MP : Feeds paper from the MP Tray.

LC1 : Feeds paper from the LC1.

LC2 : Feeds paper from the LC2.

LC3 : Feeds paper from the LC3.

When Page Size is set to envelopes (IB5, C10, C5, DL, MON, C6), Paper Source always selects the MP Tray. When Paper Type = Thick, ExtraThk, Trnsprnc, Coated, Paper Source is always set to the MP Tray.

QUANTITY

This menu sets the number of copies printed by collating a set of sequential pages (Collate printing), and it is specified prior to the Copies setting. Therefore, when Quantity is set to 2 or more, the setting value of Copies becomes invalid. Collate printing is performed by the RAM or HDD. Unless any HDD is installed, the driver uses the Quantity setting when the printer's RAM size is 64 MB or more. This setting is specified only by PJL and EJL, or the ESC/Page and ESC/PageColor commands, and the printer cannot store the setting value. If data for one job cannot be stored in the printer, the printer displays the "Collate was disabled" warning and prints only one copy.

TONER SAVE

During color printing, by controlling the halftone growth and by printing with a low density, toner consumption is reduced.

LCD CONTRAST

This function adjusts the display density of LCD by adjusting the contrast voltage of LCD. When 0 is selected, the LCD display is lowest contrast and weakest. When 15 is selected, the LCD display is highest contrast and darkest. Selecting the Up button makes the contrast higher, while selecting the Down button makes it lower. Pressing the Up or Down button changes the contrast without pressing the Enter button. By pressing the Enter button, the setting is determined and becomes effective. The timing when this setting is made effective after turning the printer on is in the on-going system check, therefore the LCD shows the default value 7 just after powering on. When the panel setting value is set to 0 and the display is too light to be visible, initialize the panel setting by restarting the printer pressing the Job Cancel button.

EPSON AcuLaser C4000/C4100/C3000 Revision F

2.1 Print Process

2.1.1 Print Process Overview

This printer is a “full color laser printer” that uses the principle of electrophotographic recording. Each YMCK color (yellow, magenta, cyan, black) has its own special drum and developer that are used in tandem, three Intermediate Data Transfer rollers are coordinated (2 IDT 1 rollers, 1 IDT 2 roller), and at the end of the process the layered color toner images produce a full color print.

The major steps of the print process are described below:

1) Charging: The drum surfaces are charged with electricity.

2) Exposure: Image areas are exposed on drums with laser radiation.

3) Developing: Image areas on drums are developed with toner.

4) Primary transfer: The toner image on drums is transferred to transfer rollers (IDT1).

5) Secondary transfer: The toner images on primary transfer rollers (IDT 1) are transferred to the secondary transfer roller (IDT 2).

6) Cleaning: Primary transfer rollers (IDT 1) are cleaned.

7) Tertiary transfer: The complete four-color toner image on the secondary transfer roller (IDT

2) is transferred to the paper.

Figure 2-1. Print Process Overview

8) Cleaning: Secondary transfer roller (IDT 2) is cleaned.

9) Electrical charge removal: The electrical charge of the paper is discharged.

10) Fusing: Toner on the paper is fixed with heat and pressure.

11) Cleaning: Residual toner on the drums and transfer rollers is collected.

2.1.3 Print Process Technical Explanation

2.1.3.1 Charging Process

This process gives an electrical charge to the surfaces of the photoconductive drums.

2.1.3.2 Exposure Process

This process uses laser light to expose the imaging drums and form an invisible electrostatic latent image on the drum surface.

2.1.3.3 Developing Process

This process builds up the images on the drum surfaces, using the toners.

2.1.3.4 Primary Transfer Process

This process transfers the toner images that have been built up on the drums, to the Primary Intermediate Transfer Drums (IDT1).

2.1.3.5 Secondary Transfer Process

This process transfers the toner images from the Primary Intermediate Transfer Drums (IDT1) to the Secondary Intermediate Transfer Drum (IDT2).

2.1.3.9 Electrical Carge Removal

This process neutralizes / removes any positive electrical charge that remains on the back of the paper due to the “tertiary transfer”, through the provision of a negative bias (negative voltage) by Detack Daw. The removal of this electrostatic charge helps to prevent the paper from sticking to, coiling around or being attracted toward the paper pathways, the fuser and the paper eject tray. In addition, this procedure prevents image disturbances that may be caused by electrical discharges and electrostatic noise.

2.1.3.6 Cleaning

This process cleans the Primary Intermediate Transfer Drums (IDT1).

2.1.3.7 Tertiary Transfer Process

This process transfers the complete 4-color toner image from the Secondary Intermediate Transfer Drum (IDT2) onto the paper.

2.1.3.8 Cleaning

This process cleans the Secondary Intermediate Transfer Drum (IDT2).

Operating Principles Print Process 2-58

EPSON AcuLaser C4000/C4100/C3000 Revision F

2.1.3.10 Fusing Process

The “Fusing” process fixes the toner to the paper using heat and pressure.

 The toner image that is transferred to the paper by IDT 2 can be easily

smudged by even a light touch of a finger, so the toner image is fixed to the paper by the FUSER ASSY (PL9.1.1). With the Heater Lamp as its heat source, the Heat Roll melts the toner, then components inside the Belt opposite the Heat Roll applies pressure to the paper and the toner is fixed in place.

 The fusing method of the AcuLaser C4000 differs from previous heat-roll

and pressure-roll fusing methods. By using a pressure method with the belt:

• Contact area for the Heat-Roll is expanded.

• Nip pressure is reduced by expansion of contact area.

• Heat transferability is improved by thinner Heat-Roll, reducing warm-up time and fusing time.

2.1.3.11 Cleaning Process

This process recovers any excess toner that remains on the image drums and on the intermediate transfer drums.

Operating Principles Print Process 2-59

EPSON AcuLaser C4000/C4100/C3000 Revision F

2.1.3.12 Cleaning (Full)

The “Cleaning (Full)” process removes residual toner from the HTC, Refresher, IDT 1 Cleaner, and IDT 2 Cleaner after the complete toner image has been transferred to the paper.

 Toner that is not transferred during the “Secondary Transfer” and “3rd

Stage Transfer” processes is retained on the IDT 1 Cleaner and IDT 2 Cleaner. The polarity also changes and toner returned to the drum is retained on the Refresher. Any toner that slips by the Refresher adheres to the HTC. The toner in these locations is cleaned after completion of the print. The method used to collect the toner on IDT 1 Cleaner and IDT 2 Cleaner is different from the method used on the Refresher and HTC.

1) IDT 1 Cleaner, IDT 2 Cleaner

The same high voltage used during the print transfer process is applied to IDT 1, IDT 2 and BTR. By applying zero volts to the IDT 1 Cleaner and IDT 2 Cleaner, any remaining toner (negative polarity) on the IDT cleaners is transferred by electric charge to IDT 1 and IDT 2. From that point, as with the print transfer process, the electric potential difference of IDT 1, IDT 2 and BTR causes the remaining toner to be collected on the BTR surface.

Figure 2-5. Cleaning 1

Operating Principles Print Process 2-60

EPSON AcuLaser C4000/C4100/C3000 Revision F

2) Refresher, HTC

High voltage opposite that used during the print transfer process (negative) is applied to IDT 1, IDT 2 and BTR. The drum surfaces are negatively charged by contact with IDT 1 rollers. By applying zero volts to the Refresher and HTC, residual toner (positive polarity) on the Refresher and HTC is transferred by electric charge to the drums. From that point, as with the print transfer process, the electric potential difference of IDT 1, IDT 2 and BTR causes the remaining toner to be collected on the BTR surface.

 Toner picked up by the BTR surface is scraped off by the Scraper and

collected in the toner collection space inside the BTR ASSY (PL9.1.2).

2.5.8.1 Main Functions

ROS ASSY (PL11.1.1) The ROS ASSY (Raster Output Scanner Assembly) is an exposure device that sends out laser radiation to form electrostatic images on the surface of the drum. In this manual, items related to the ROS ASSY are simply called ROS.

The ROS ASSY is constructed of the following main components:

• Quad Beam Laser Diode

• Scanner Motor Assy

• SOS PWB

• Lens

• Mirror

• Window

 PHD ASSY (PL11.1.3)

The PHD ASSY is constructed of the following components:

• Drum (Y) • Developer (Y)

 CHUTE ASSY REGI (CLUTCH REGI) (PL10.1.1)

The CHUTE ASSY REGI is constructed of the CLUTCH REGI (PL10.1.12), the ROLL REGI RUBBER (PL10.1.10) and the ROLL REGI METAL. Driving force is transferred from the DRIVE ASSY MAIN (PL14.1.2) to the ROLL REGI RUBBER by the CLUTCH REGI (PL10.1.12), and the paper is conveyed toward the PHD ASSY from either the Tray path or the MSI path. In addition, when the leading edge of the paper reaches the CHUTE REGI (PL10.1.14), the CLUTCH REGI becomes a retaining loop for the paper until the ROLL REGI RUBBER begins rotating, and it corrects skew of the paper edge to ensure proper feed.

 SENSOR REGI (Regi Sensor) (PL10.1.20)

Detects the leading edge of the paper when it reaches the CHUTE REGI. (Paper present: sensor receiving)

 SENSOR OHP (PL10.1.16)

Regular paper scatters radiated light, and the SENSOR OHP catches that reflected light, detecting the paper. OHP (Over Head Projector) transparencies do not scatter much direct light, so the SENSOR OHP cannot catch any reflected light. This method determines if the sheet being fed from the MSI is an OHP transparency or regular paper.

2.7 Mode

2.7.1 Print Mode

There are three print modes: Normal Mode, High Resolution Mode, and High Gloss Mode. These modes have sub-categories based on resolution (600 dpi/ 1200 dpi) and process speed (full speed/half speed). When process speed is set to half speed, video data transfer speed to the ROS is double the 600 dpi speed, yielding 1200 dpi resolution.

1. Use Normal Mode to print at 600 dpi

2. Use High Resolution Mode to print at 1200 dpi on plain paper

3. Use High Gloss Mode at 600 dpi with half speed to improve gloss on plain paper

Relationships of resolution, process speed, paper and print mode are shown below.

2.8.2 Paper Supply Selection Control

When not actively controlled by the Printer Controller, TRAY 1 is selected as the paper supply when the power is turned ON.

NOTE: “TRAY 1” is used as the name for the printer’s internal paper

supply, “TRAY 2” is the first level of the optional TRAY UNIT and “TRAY 3” is the second level of the TRAY UNIT.

2.8.3 ROS Light Control

Image data enters the laser diode of the ROS ASSY as an electric signal (data is expressed by high/low condition of the voltage), and the laser diode converts that electric signal to a light signal (data is expressed by on/off condition of the light). Occurrence of variations such as fluxuations in laser radiation quantity, irregularities in the optics (such as the lens) or variations in the sensitivity of the drum can prevent the formation of a suitable electrostatic image, so the laser diode monitors the laser radiation quantity and controls it in order to always obtain a suitable electrostatic image. The ROS in this printer has four separate laser diodes, one each for yellow, magenta, cyan and black, and quantity of laser radiation is automatically adjusted for each.

2.8.4 PROCESS CONTROL

In order to render a stable print, timely correction of image formation parameters is needed. Control of the entire process that includes parameter adjustment control is called “PROCESS CONTROL”.

The following two items are the main controlling functions:

• Potential Control

• Toner Density Control

The controlling functions above are supplemented by the following functions:

• High Area Coverage Mode

• Admix Mode

• SENSOR ASSY ADC (PL6.1.11) LED Light Quantity Setting

2.8.4.1 POTENTIAL CONTROL

In order to obtain stable print image density, POTENTIAL CONTROL regulates the drum charge voltage and the developer DC voltage to match the fluctuating developer capability moment by moment. Adjusted drum charge voltage and developer DC voltage is monitored, and a fixed level of print image density is maintained.

An overview of POTENTIAL CONTROL is shown below.

1) Temperature and humidity is measured by the SENSOR HUM TEMP (PL4.2.4) and target values are set for drum charge voltage and developer DC voltage.

2) A POTENTIAL CONTROL patch for each color (yellow, magenta, cyan, black) is formed and transferred to the BTR surface. (The shape of the patches is shown below.)

POTENTIAL CONTROL performs its functions just before printing starts under the following conditions:

• When printing the first page after power has been turned on

• When the number of pages lined up for printing is 16 or more

• When performing a cleaning cycle between a series of pages to be printed

3) Density on the portion of the BTR surface not holding toner and density of the patch are both measured by the SENSOR ASSY ADC (Density Sensor).

4) Density measurements taken at Step 3) are compared with target values set in Step 1). Adjustments to drum charge voltage and developer DC voltage for each color are made according to the difference in the values.
