Safety Precautions

All safety procedures described here shall be strictly adhered to by all parties servicing and maintaining this product.

DANGER

Strictly observe the following cautions. Failure to comply could result in serious bodily injury or loss of life.

1. Always disconnect the product from the power source and peripheral devices when servicing the product or performing maintenance.

2. When performing works described in this manual, do not connect to a power source until instructed to do so. Connecting to a power source causes high voltage in the power supply unit and some electronic components even if the product power switch is off. If you need to perform the work with the power cable connected to a power source, use extreme caution to avoid electrical shock.

WARNING

Strictly observe the following cautions. Failure to comply may lead to personal injury or loss of life.

1. Always wear protective goggles for disassembly and reassembly to protect your eyes from ink in working. If any ink gets in your eyes, wash your eyes with clean water and consult a doctor immediately.

2. 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.

PRECAUTIONS

Strictly observe the following cautions. Failure to comply may lead to personal injury or damage of the product.

1. Repairs on Epson product should be performed only by an Epson certified repair technician.

2. No work should be performed on this product by persons unfamiliar with basic safety knowledge required for electrician.

3. The power rating of this product is indicated on the serial number/rating plate. Never connect this product to the power source whose voltages is different from the rated voltage.

4. Replace malfunctioning components only with those components provided or approved by Epson; introduction of second-source ICs or other non-approved components may damage the product and void any applicable Epson warranty.

5. In order to protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static wrist straps, when accessing internal components.

6. Do not tilt this product immediately after initial ink charge, especially after performing the ink charge several times. Doing so may cause ink to leak from the product because it may take some time for the waste ink pads to completely absorb ink wasted due to the ink charge.

7. 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 you have a skin irritation, consult a doctor immediately.

Confidential

8. When disassembling or assembling this product, make sure to wear gloves to avoid injuries from metal parts with sharp edges.

9. Use only recommended tools for disassembling, assembling or adjusting the printer.

10. Observe the specified torque when tightening screws.

11. Be extremely careful not to scratch or contaminate the following parts.

Nozzle plate of the printhead

CR Scale

PF Scale

Coated surface of the PF Roller

Gears

Rollers

LCD

Scanner Sensor

Exterior parts

12. Never use oil or grease other than those specified in this manual. Use of different types of oil or grease may damage the component or give bad influence on the printer function.

13. Apply the specified amount of grease described in this manual.

14. Make the specified adjustments when you disassemble the printer.

15. When cleaning this product, follow the procedure described in this manual.

16. When transporting this product after filling the ink in the printhead, pack the printer without removing the ink cartridges in order to prevent the printhead from drying out.

17. Make sure to install antivirus software in the computers used for the service support activities.

18. Keep the virus pattern file of antivirus software up-to-date.

2.2 Revision FDetails of Adjustments

This section provides adjustment procedures for which explanation in details is necessary. See " 2.1 Required Adjustments (p24)" for the adjustments not explained here.

2.2.1 TOP Margin Adjustment

Three adjustment patterns are printed on the top of the paper as shown in Figure 2-1.

Figure 2-1. Top Margin Adjustment Printout Pattern

How to Judge

Check if the top edge of the paper is within -3 to +3 steps from the standard line.

Additional Information

If it is not within the OK range, select the adjustment value (-4 to +4 steps) on the adjustment program to adjust the top edge of paper until it becomes within -3 to +3 steps from the standard line. Then, print the adjustment pattern again to check the result.

The patterns are printed on three sections. If those three patterns are in different position to the top edge of paper, the paper was fed on a skew. Set the papers correctly and print it again to adjust the top margin correctly.

The following pattern is printed with the optimal adjustment value.

MAINTENANCE

3.1 Overview

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

3.1.1 CleaningExcept for the printhead, there are no other mechanism components that require periodic cleaning. However, if need arises, clean the component observing the following instructions.

Instructions for cleaning

Exterior parts such as housingWipe dirt off with a soft clean cloth moistened with water. For parts with glossy surfaces or transparent parts, use of unwoven cloth is recommended to avoid scratching those parts.

Inside of the printerRemove paper dust with a vacuum cleaner.

Rubber or plastic rollers such as an LD roller used to feed paperIf paper dust adhered to the rollers decreases the frictional force of the rollers and the rollers cannot properly feed paper, wipe off the paper dust with a soft cloth moistened with diluted alcohol.

Instructions for cleaning ink stains

Wipe the stains off with a cloth wrung out of diluted alcohol.

3.1.2 LubricationThe type and amount of the grease used to lubricate the printer parts are determined based on the results of the internal evaluations. Therefore, refer to " 3.2 Lubrication Point (p29)" for the repairing procedures below, and apply the specified type and amount of the grease to the specified part of the printer mechanism.

Grease

Tools





Do not use alcohol for cleaning the transparent parts. Doing so may cause them to get cloudy.

When wiping paper dust off the LD roller, be careful not to rub against the surface asperity.

To minimize the effect on the parts, use diluted alcohol such as 70% diluted ether. After using alcohol for cleaning, make sure to wipe the part off with a soft dry dust-free

cloth to remove alcohol traces fully.
