OPERATION SEQUENCE OVERVIEW (FRONT ASF)

ASF motor (CCW)

The operation of the front paper feeding mechanism is described below. 1. Spur gear18.5

3. ASF Planetary gear CCW: to drive Pick-up roller CW: to drive LD roller

2. Combination gear 25.5, 20.8, 11.2

1.

The condition before starting paper feeding is like below due to the power-on sequence or the previous paper feed sequence. Front position sensor L (Front Retard Home) Rear Home sensor L (Rear Home) Rear position sensor H (Rear Pos.) In this condition, Rear ASF is in its home position and the Front Retard roller is in the Home position (down). At this time, RASF Planetary gear is free from the cam of the Spur gear 34.4, so the ASF Sub motor can cause either the Rear ASF hopper to drive or the Front Retard roller to move up/down. See Flowchart 2-4 (p.37)/ Figure 2-3 (p.27)/ Flowchart 2-7 (p.40).

2.

When starting paper feed from the Front ASF, the PF motor rotates clockwise a specified number of steps to move the FASF Planetary gear toward the Idle roller side. See Figure 2-14“PF motor drive force transmission” (p.37).

3.

The counterclockwise rotation of the ASF Sub motor moves the RASF Planetary gear toward the Front Retard side. The ASF Sub motor keeps counterclockwise rotation to lift up the Front Retard. At this time the Front Position sensor is monitored. When the Front position sensor becomes High state, the rise of the Front Retard is completed and the ASF Sub motor stops. In this manner the Front Retard comes into with the Idle roller. This allows the paper to be fed by the rotation of the Idle roller. See Flowchart 2-4 (p.37)/ Figure 2-15 (p.39).

The rotation of the Pick-up roller feeds the paper to the Idle roller/Front Retard roller in the cassette. When the ASF motor rotates a specified number of steps, the paper reaches the Idle roller/Front Retard roller. Then those rollers which are started to rotate in step 4 transport the paper until it is detected by the PE sensor. At this time the ASF motor is decelerated to stop the rotation of the Pick-up roller.

4.

The clockwise rotation of the PF motor causes the Idle roller/Front Retard roller to rotate. Then the printer starts to monitor the paper with the PE sensor.

7.

5.

The rotation of a specified number of steps of the PF motor causes the ASF motor to rotate counterclockwise to move the ASF Planetary gear toward the pick-up roller side. The ASF motor keeps counterclockwise rotation monitoring load to drive the pick-up roller, and the front feeding is started. (If a high load is detected while the ASF motor rotates a specified number of steps, the printer judges that no paper is loaded and indicates the Paper Out error.) See Flowchart 2-6 (p.38).

When the PE sensor detects the paper presence, the paper is moved forward a preset number of steps to the print position. With this step the Front paper feeding operation is completed. Then the PF roller which is rotated by the PF motor starts the further paper feeding operation.

8.

After the Front paper feeding operation is completed, the ASF motor rotates counterclockwise to bring the Front Retard roller down so that it returns to the home position. When the Front Position sensor goes to Low state, the ASF Sub motor is stopped.

Revision B

ASF motor (CW)

4.

The clockwise rotation of the ASF motor moves the ASF Planetary gear toward the LD roller to start the rear feeding. From this time the printer starts to monitor the feeding operation using the PE sensor. At the same time the PF motor starts to rotate clockwise to rotate the PF roller. See Flowchart 2-8 (p.41).

5.

When the PE sensor detects the paper presence, the ASF/PF motor is driven to correct the paper skew. Then the paper is moved forward in a preset number of steps to the print position. With this step the rear paper feeding operation is completed. In the next step, the PF roller driven by the PF motor starts the paper feeding process.

6.

While the printer monitors the Rear Position sensor, the ASF sub motor rotates clockwise to cause the hopper release cam to move the hopper toward the print position and the Paper Back cam lifts the Paper Back lever up to avoid double feed.

OPERATION SEQUENCE OVERVIEW (REAR ASF) The operation of the rear paper feeding mechanism is described below. 1.

Before starting the Rear ASF paper feeding, the Rear ASF is in its home position as it does before the front feeding. (Step 1.“ Operation Sequence Overview (front ASF) (p.38)”)

2.

The clockwise rotation of the ASF Sub motor moves the RASF Planetary gear toward the Hopper, and the printer starts to monitor the Rear Position sensor. The Rear Position sensor goes to low state after the ASF Sub motor starts to rotate. The motor stops when the sensor becomes high state. See Flowchart 2-7 (p.40).

3.

The driving force of the ASF Sub motor causes the Paper Back cam to press down the Paper Back lever, and the Hopper Release cam lifts the hopper so that the hopper s the LD roller. See Flowchart 2-7 (p.40).

The driving force from the PF motor causes the Planetary gear in the Duplex unit to move so that the paper is fed inside the Duplex unit. Both the rotational directions of the motor cause the operation, however, to reduce wear of rollers and motor load, the driving force from the clockwise rotation of the PF motor is not transmitted to the Duplex unit (this is referred to as “Duplex Auto Shutoff” in this manual) in cases listed below. (The counterclockwise rotation of the PF motor always moves the Duplex unit.)

1.

Paper rear edge detection for setting the reverse standard position After the printing on the front side is completed, the PE motor transports the paper until its Rear edge is detected by the PE sensor. Because the Duplex unit is in the “Duplex Auto Shutoff” state, the PF motor clockwise drive is not transmitted.

2.

Drying the front printed side The PF motor pauses for a fixed time period specified by the printer driver for drying the paper (1st dry process) and the printer indicates on the LCD that it is in the drying process. Then, the PF motor rotates clockwise to transport the paper until its rear edge reaches the EJ roller, and pauses again for drying the paper for a fixed time period specified by the driver for 2nd dry process.

Detection of the rear edge of the paper after drying After the drying sequence, the drying indication on the LCD disappears and then the PF motor rotates counterclockwise until the PF sensor detects the paper presence.

4.

Transporting into the Duplex unit After the PF sensor detects the paper, the PF motor rotates a specified number of steps to transport the paper to the reverse start position and then stops. At this time the printer quits the Duplex Auto Shutoff state so that the clockwise rotation of the PF motor is transmitted to the Duplex unit.

5.

The state of the CDR guide is controlled by the flag and the CDR mode sensor. If the misalignment with the CDR guide is detected, the CDR retrying sequence is performed to correct the misalignment by moving the CDR guide up/down according to the state of the flag. The operational sequences of the CDR guide Up/Down are described below. † Lifting the CDR guide (CDR printing position) 1.

The PG position is switched to the CDR guide drive position by the APG mechanism to release the lock of the CDR Planetary gear. See Figure 2-27.“Switching of CDR Link arm and Planetary gear (When lifted)”(p.47).

4.

After the moving down the CDR guide is completed, the PF motor rotates counterclockwise a specified number of steps to release the pressure of the CDR Planetary gear. Then the PG position is switched to the PG(-) by the APG mechanism. In this manner the CDR Planetary gear is locked so that the driving force of the PF motor is not transmitted.

The Ink system consists of the mechanisms shown below.

The Cap unit is provided to keep the airtightness inside the cap by capping the surface of the printhead when the ink is absorbed by the Pump unit. When the carriage unit moves to the absorbing position on the edge of HP side, the carriage causes the cap to slide so that the cap goes up and adhere to the head.

Wiper

Also the Cap unit contains the Carriage Lock unit and the Wiper unit. When the carriage is in the carriage lock position/wiping position, the carriage lock set/reset and wiper set/ reset operations are conducted by the driving force of the PF motor.

LED

The Scanner unit consists of the Scanner Carriage unit, CR motor, CR encoder sensor, etc. See Figure 2-4.“Motors/sensors layout (scanner unit)”(p.27). Following describes the mechanism of the components. CIS

† Scanner Carriage Unit The Scanner Carriage unit consists of the CIS board, the Rod Lens Array, and the LED (light source). The following explains about each of the components. „

CIS Board

Scanner Carriage Unit

The CIS Board contains the sensing elements that are placed across the entire width of an original. The sensing elements, which does not install a color filter, read an original through the Rod Lens Array by turning on red, green, and blue light emitting diodes (LEDs) alternately. It is not the CIS Board but the Main Board that converts the analog light signal read by the Rod Lens Array into digital signal. „

Rod Lens Array A number of rod-shaped lenses, which are arranged on the sensing elements, are also placed across the entire width of an original. The light source (LEDs) emits light, and these lenses read the light reflected off the original, and the information to the sensing elements. Compared to conventional CCD method, this optical system allows the focal length (distance between sensor and image scanned) to be shallow. Therefore, an original to be scanned should be brought close to the document glass. The optical system, in addition, is 1:1, (there is no optical reduction or enlargement) and this results in a scanner offering the solid performance in of accuracy.

The parallel printing is realized by the adoption of SOC06H which has one main processor and six processors for image processing

„

The wide memory access is realized by mounting the 166Mhz DDR1SDRAM on the local side as the image processing memory.

„

The ASIC with a built-in U is adopted for card controlling. The connection method with SOC is changed from the previous U bus connection to the USB Host connection to improve the card access speed. This IC has the threeports USB2.0 HUB function and using one port for the external USB Host I/F realizes the USB2.0 Host function.

„

Installing the IC which adopts to Multi-common reduces the number of printing paths so that the printing process time is shortened.

„

The costs for the logic power supply and the drive of motors are reduced by installing A6651, a motor driver with a built-in power source.

2.4 Banding Reduction System (BRS) / Paper Feed Amount Profile Correction (PFP) † Overview In order to ensure high print quality and high print speed, this product incorporates the Banding Reduction System (BRS) and Paper Feed Profile (PFP) Correction system. The overview of them is described in the table below. Table 2-15. Overview of BRS and PFP Type

BRS

Conventional models perform overlapping printing (2-path or 4path print) to reduce banding problem. Printers that incorporate the Banding Reducing System do not perform the overlapping printing. They carry out 1-path printing correcting ink drop amount for each raster mode in order to avoid making a gap between each path (printed line). This enables to achieve both high print quality (less banding) and high print speed.

PFP

In the conventional method to improve paper feed accuracy, the adjustment value is calculated based on a value obtained at a certain point of paper. Therefore, correcting the total paper feed amount (from when paper is fed and to when finishing printing) was impossible. The Paper Feed Amount Profile Correction offers more precise control over the paper feeding. Paper feed errors are measured at various points and a correction value is calculated for each of the points. This enables to ensure print quality in the target print mode.

5.3 Adjustment without Using Adjustment Program

CAUTION

This section explains the adjustment procedure without using the adjustment program.

„ „ „

5.3.1 PG Adjustment Described below is the platen gap (PG) adjustment. † Purpose: Adjust the distance between the head surface and the Paper Guide Front Assy (platen) properly and adjust the parallelism on the 0th column side and on the 80th columns side to ensure reliable print quality. Once the Carriage Assy and/or Adjustment Bushes have been removed or whenever necessary for any other reason, make this adjustment to correct the deviation of the platen gap. Table 5-5. PG Positions Position

Application for Printing (selected from PG flag list for normal/head rubbing)

PG Size (mm)

CHECK POINT

„

„

The thickness gauge to be used must be free from dust and dirt and from deformation. Be sure to clean it before use. Take care that the Print Head is not soiled or scratched. To ensure high accuracy of adjustment, install new ink cartridges in the carriage, and move the carriage right and left by pulling the belt without holding the carriage. Make this adjustment after installing the mechanism unit in the Lower Housing. (Install the Linear Scale after adjustment.) Refer to “4.5.4 Printer Mechanism” (p.114) With EPSON Stylus Photo RX680/RX685/RX690, four stages of PG setting are available by means of the APG Mechanism. However, make this adjustment with the mechanism in the minimum PG position (PG-: 1.2 mm). (Refer to “4.5.7 APG Assy/Sub Board/ASF Encoder/Retard ASF Assy” (p.120) and below.)

The display on the LCD may not change at all even if the belt is flipped. In this case, flip the belt again after a few seconds. Carry out this adjustment in a quiet place to avoid inaccurate measurement results due to the surrounding noise. Some measurement results may differ greatly because of inaccurate measurement. In such case, flip the belt again to obtain the two results whose values are most close to each other. The errors are within the range between 1/100 and 5/100, which ensures high reliability of measurement results. Standard value: 9.3 ± 1.5N Screw tightening torque of PF Motor: 4 ± 0.5 kgf.cm

CHECK POINT

Depending on the sensor type of the scanner to use for the adjustment, drying time required after the BRS adjustment pattern has been printed differs. For PFP adjustment pattern/PFP check pattern, drying time is not required. „ For “CCD” sensor: Printed pattern can be scanned straight away. (Drying time of about 2 minutes is recommended.) „ For “CIS” sensor: Printed pattern needs to be dried more than 5 minutes. Calculate correction value

† Specified Scanner to perform the adjustment CAUTION

MAINTENANCE


Revision B

6.1 Overview

6.1.2 Service Maintenance If any abnormal print (dot missing, white line, etc.) has occurred or the printer indicates the “Maintenance request error”, take the following actions to clear the error. (This error is displayed in EPSON Status Monitor 3 and in the LCD .)

This section provides information to maintain the printer in its optimum condition.

6.1.1 Cleaning This printer has no mechanical components which require regular cleaning except the Print Head. Therefore, when returning the printer to the , check the following parts and perform appropriate cleaning if stain is noticeable. CAUTION

„

„ „

„ „

Never use chemical solvents, such as thinner, benzine, and acetone to clean the exterior parts of the printer like the Housing. These chemicals may deform or deteriorate the components of the printer. Be careful not to damage any components when you clean inside the printer. Do not scratch the coated surface of the PF Roller Unit. Use soft brush to wipe off any dusts. Use a soft cloth moistened with alcohol to remove the ink stain. Use a soft cloth moistened with alcohol to remove the ink stain. When using compressed air products; such as air duster, for cleaning during repair and maintenance, the use of such products containing flammable gas is prohibited.

6.1.2.1 Print Head cleaning When dot missing or banding appears on images, run the Print Head cleaning cycle.* The cleaning be activated from the control , the printer driver utility or the Adjustment program. Note * : This printer has three manual cleaning modes. The appropriate cleaning mode is automatically selected and performed according to various conditions. The ink consumption amount for manual cleaning varies depending on the mode.

6.1.2.2 Maintenance request error Ink is consumed also for cleaning and flashing operations. When the ink is used for cleaning and flashing operations, the ink is drained to the Waste Ink Pads via the Pump. The amount of the waste ink is stored as the waste ink counter into the EEPROM. When the waste ink counter has reached the limit of the absorbing capability of the Waste Ink Pads, the maintenance request error is displayed. This printer takes the ink evaporation amount into consideration, therefore the counter limit differs depending on how often printing is made. CHECK POINT

† Exterior parts Use a clean soft cloth moistened with water, and wipe off any dirt. If the exterior parts have ink stain, use a cloth moistened with neutral detergent to wipe it off. † Inside the printer Use a vacuum cleaner to remove any paper dust. † LD Roller/Retard Roller/Idol Roller/Front Retard Roller When paper loading function does not operate because of a drop in friction force of the LD Roller and the other rollers above due to paper dust, use a soft cloth moistened with alcohol to remove the paper dust.

MAINTENANCE

For display of Maintenance request error, see the following. „ Chapter3 "TROUBLESHOOTING" (p.55)

When the maintenance request error appears, replace the Waste ink pads with a new one and reset the waste ink counter using the Adjustment program. If the waste ink counter is close to its limit, recommend that the Waste ink pads will be replaced with new one. This is because the “Maintenance request error” will may occur after returning the repaired product to the customer.
