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. The capacitors on the Main Board may be electrically charged right after the power turns off or after driving motors which generates counter electromotive force such as when rotating the PF Roller or when moving the CR Unit. There is a risk to damage the Main Board if the Head FFC is short-circuited with the capacitors on the Main Board electrically charged, therefore, after the power turns off or after motors are driven, leave the printer untouched for approximately 30 seconds to discharge the capacitors before starting disassembly/ reassembly.

6. To prevent the circuit boards from short-circuiting, be careful about the following when handling FFC or cables.



When handling FFC, take care not to let the terminal section of FFC touch metal parts.

 When connecting cables/FFC to the connectors on circuit boards, connect them straight to the connectors to avoid

slant insertion.

Confidential

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

8. 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.

9. 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.

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

3-2.The CR Unit moves to the 0-digit side slowly.

3-3.After the PE Sensor checks if paper exists, the PF Motor rotates clockwise for one second and releases the CR lock.

3-4.While checking if the CR Unit does not touch the Change Lever (CR lock) or the foreign material, the CR Unit

moves to the 80-digit side slowly until it touches the Left Frame.

3-5.The distance from the position where the CR Unit touched to the Left Frame is regarded as the standard distance

from the origin position, and the home position is fixed. From then on, the CR Unit position is monitored according to the signals from the CR Encoder.

3-6.The CR Unit moves to near its home position quickly.

4. Detecting ink cartridge and initializing ink system

4-1.To detect ink, the CR Unit moves back and forth between near the Change Lever and near the Left Frame for two

times.

4-2.The CR Unit returns to its home position.

5. Low temperature operation sequence

5-1.The CR Unit quickly moves back and forth between near the Change Lever and near the Left Frame for two times.

Note 1: The rotation directions of the PF Motor are as follows.

Clockwise: Paper is fed normally Counterclockwise: Paper is fed backward

Operation

Executes No.1 to No.3 on the normal power-on sequence (Table 1-1).

4. Detecting remaining paper

4-1.5.The CR Unit returns to its home position.

4-2.The CR Unit moves to the 80-digit side and confirms there is no paper.

4-3.The CR Unit quickly returns to its home position, and displays on the LCD or with flashing LEDs that the paper jam

error occurs.

When the user removes the paper and releases the paper jam error by panel operation, the normal power-on sequence from No.1 (Table 1-1) is executed

again.

Note *1: “Paper exists” is detected when the CR Unit touches the paper. When “paper does not exist” is detected, the power-on sequence

of condition 1 (Table 1-1) is executed from No.4.

 To recover from the maintenance error, the dedicated software that can be downloaded

from the web site which can be accessed from STM3 is required.

 The printer operation related to the maintenance error recovery is as follows.

• When the waste ink counter reaches the threshold value (1) for the first time and the maintenance error occurs, the counter threshold of the maintenance error is changed to threshold value 2 after performing recovery from the maintenance error.

• After the threshold value (2) is enabled, the warning; to notify the possibility of ink leakage out of the printer, is displayed every time the waste ink counter increases by 1%.

• If the waste ink counter reaches the threshold value (2), the maintenance error occurs. Then, the waste ink counter is changed back to the threshold value (1) after recovering from the maintenance error, and the warning is displayed repeatedly according to the increment of the waste ink counter until the maintenance error occurs when the threshold value (2) is reached. (Recovery from the maintenance error can be performed up to the specified number of times.)

2.1.5 Checks and Precautions before Disassembling

2.1.5.1 Factors which Affect the Print Quality

HOW TO PLACE THE INK TANK ASSY WHEN DISASSEMBLING/REASSEMBLING

The film under sealing film attached on the Ink Supply Tank Assy of this printer is ventilation film. The ink in the ink tanks is vented to atmosphere through this film to keep ink supply to the Printhead stable. If the film gets wet with ink, the ink in the tanks is not properly vented and printing may not be capable.

In order to prevent this from occurring, make sure to place the Ink Supply Tank Assy as shown below after removing it.

Revision A

Ink Supply Tank Assy

Do not place the Ink Supply Tank Assy with its film side down. Otherwise, ink in the Ink Supply Tank Assy may reach and cover the ventilation film, and the printing failure may occur.

MEANS DO TO MINIMIZE THE INK SPILL

Even observing the points described in this section, ink may spill in the following situations. Therefore, be careful not to contaminate the inside of the printer or its surroundings by preparing the container to receive the leaked ink, or the like.

 When removing the Ink Supply Tank Tube Assy (w/Valve Assy), some ink will spill from

both ends of the tube even the Valve Lever is closed.

 When removing the Ink Supply Tube Assy, all the ink in the tube will spill.

Before disassembling, confirm that the printer is in the following condition.

 Choke Valve is closed

Do not turn the Valve Lever too much when closing the Choke Valve, otherwise, the Valve Lever and/or Valve Assy may get damaged.

Before disassembling:



Turn the Valve Lever and be sure to close the Choke Valve.

 After reassembling is complete:

Open the Choke Valve to perform the print inspection.

 Before returning the printer to the user after repairing:

Make sure to turn the Valve Lever up to the choke position to close the Choke Valve before packing the printer.
