7.3 Backup Functione Backup Memory Card function provided in the Setup mode allows the user to ke a backup copy of a memory card on a media in an external device. Printing the ked up images directly from the external device also can be made. Writing back a backed up on the external media to a memory card cannot be made. e available media for the backup are as follows.

HECKPOINT

Due to the file system restriction, a backup of a memory card that has eight or more levels deep in folder hierarchy cannot be made on an ISO 9660 Level1-formatted CD-R.Due to the logical format of the CD/DVD, the pathname length is restricted as described below;•Destination media

ISO9660: up to 255byte Joliet: up to 240byte

•Source media: Memory card (FAT12/16/32): up to 260byte

HECKPOINT

The maximum number of writing times• FAT12/16-formatted media: up to 512 times (001 to 512)

If any files other than backup folders exist in the route directly, the max. number of writings becomes less than 512 due to the MS-DOS restriction. When more than 512 times of writing history of an inserted MO is detected, the printer handles it as a backup error (file name, to folder hierarchy error).

• CD-R: 640MB: up to 47 times 700MB: up to 50 times

This is because each session information must be saved.• DVD-R: 4.7GB: up to 274 times

This is because each session information must be saved.

2.4 Paper Loading/Feeding Mechanisme paper loading mechanism consists of Front ASF, Rear ASF and CDR guide. This chanism transports the paper from each ASF or CDR guide to the paper feeding chanism such as PF roller. When the optional Duplex Print unit is installed, omatic duplex printing is available. After printing on the front side, the paper is omatically reversed in the Duplex Print Unit to print on the back side.e outline of the paper loading/feeding mechanism is described below.

en a print job is started from the printer driver or the control panel, the printer cks the selected paper path and print data for any error. Then the printer sets the PG ition using the APG and moves the carriage toward 80 digit side from its home ition. The motors of the ASF mechanism then start to move to load the paper or CD.

e fed paper is transported to the PF roller and its skew is corrected, and the paper is nsported to the print position. Then the paper feeding mechanism starts, and the er is transported up to the paper ejecting process. This printer is equipped with three es of paper feeding mechanism; Front ASF, Rear ASF and CDR guide.

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.

ERATION SEQUENCE OVERVIEW (REAR ASF)

e operation of the rear paper feeding mechanism is described below.

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)”)

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).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 contacts the LD roller. See Flowchart 2-7 (p.40).

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

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

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 pass 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 terms of accuracy.

LED

Stylus Photo RX680/RX685/RX690 use three color LEDs (red, green, and blue) to illuminate the line to be scanned in the document. Unlike cold cathode fluorescent lamp used in CCD method, usage of LEDs requires no warm-up time and allows the CIS to be highly power efficient.

PERATING PRINCIPLES Electrical Circuits Operating Principles

3 Electrical Circuits Operating Principlese electric circuits of the Stylus Photo RX680/RX685/RX690 consists of the lowing boards.

3.1 FeaturesThe 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 DDR1-SDRAM on the local side as the image processing memory.

The ASIC with a built-in CPU is adopted for card controlling. The connection method with SOC is changed from the previous CPU bus connection to the USB Host connection to improve the card access speed. This IC has the three-ports 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.

The MW buffer size is reduced to one-third compared to that of Stylus Photo RX700 by installing UBEC (Ultra Block Encode).

The color LCD (2.5 inch TFT display) is installed as standard.

PERATING PRINCIPLES Banding Reduction System (BRS) / Paper Feed Amount Profile Correction

4 Banding Reduction System (BRS) / Paper Feed Amount Profile CorrectOverview

order to ensure high print quality and high print speed, this product incorporates the Banding Reduction System (BRS) and Parview of them is described in the table below.

Adjustment/Correction method

rrection values of the BRS and the PFP are automatically calculated when a pattern printed by the printer is scannedlues are stored into the serial flash ROM on the main board, and applied when printing in the target print mode.

Table 2-15. Overview of BRS and PFP

Type SummaryTarget Print Mode

Paper Type Paper Size

BRS

Conventional models perform overlapping printing (2-path or 4-path 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.

DISASSEMBLY AND ASSEMBLY Overview 88

4.1 OverviewThis section describes procedures for disassembling the main components of the Stylus Photo RX680/RX685/RX690 .

Unless otherwise specified, disassembled units or components can be reassembled by reversing the disassembly procedure.

Procedures which, if not strictly observed, could result in personal injury are described under the heading “WARNING”.

Precautions for any disassembly or assembly procedures are described under the heading “CAUTION”.

Chips for disassembling procedures are described under the heading “CHECK POINT”.

If the assembling procedure is different from the reversed procedure of the disassembling, the procedure is described under the heading “REASSEMBLY”.

Any adjustments required after disassembling the units are described under the heading “ADJUSTMENT REQUIRED”.

When you have to remove any units or parts that are not described in this chapter, refer to the exploded diagrams in the appendix.

Read precautions described in the next section before starting.

4.1.1 PrecautionsSee the precautions given under the heading “WARNING” and “CAUTION” in the following column when disassembling Stylus Photo RX680/RX685/RX690 .

WARNING Disconnect the power cable before disassembling or assembling the printer.If you need to work on the printer with power applied, strictly follow the instructions in this manual.Wear protective goggles to protect your eyes from ink. If ink gets in your eye, flush the eye with fresh water and see a doctor immediately.Always wear gloves for disassembly and reassembly to avoid injury from sharp metal edges.Use static discharge equipment such as anti-static wrist straps when accessing internal components to protect sensitive electronic components and circuitry.Never touch the ink or wasted ink with bare hands. If ink comes into contact with your skin, wash it off with soap and water immediately. If irritation occurs, contact a physician.Make sure the tip of the waste ink tube is located at correct position when reassembling the waste ink tube, or it will cause ink leakage.

CAUTION When transporting, do not remove the ink cartridges. Pack the printer with the cartridges installed. Use only recommended tools for disassembly, assembly or adjustment of the printer. (Table 4-1 "List of Tools" (p.89))Be sure to tighten the screws to the specified torque.Apply lubricants and adhesives as specified. (See Chapter 6 "Specified Lubricant" (p.175) for details.)Make the specified adjustments when you disassemble the printer. (Chapter 5 contains additional information on adjustments.)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.Be careful not to scratch or damage the coating on exterior surface of the product during disassembly and reassembly.

MAINTENANCE Overview 174

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

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

Exterior partsUse 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 printerUse 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.

6.1.2 Service MaintenanceIf 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 panel.)

6.1.2.1 Print Head cleaningWhen dot missing or banding appears on images, run the Print Head cleaning cycle.* The cleaning be activated from the control panel, 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 errorInk 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.

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.

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.

CHECKPOINT

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



6.1.3 LubricationThe type and amount of the grease used to lubricate the printer parts are determined based on the results of the internal evaluations. Be sure to apply the specified type and amount of the grease to the specified parts during servicing mentioned below.
