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, fo r 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.

2.1.4 Checks and Precautions before Disassembling

2.1.4.1 Factors which Affect the Print Quality

VENTILATION FILM GETS WET

The ventilation film is under the sealing film of the ink tank unit. The atmosphere in the ink tank is vented to the outside through this ventilation film in order to keep the ink supply to printer head stably. If the ventilation film gets wet, the atmosphere in the ink tank can't be vented to the outside and maybe have a trouble for printing.

Figure 2-1. Ventilation film

 How to check the ventilation film gets wet

 If the ventilation gets wet, the tank should be replaced. Because we can’t judge the

ventilation film wet by visual evaluation, we can check the air chamber where the ink reach.

DIFFERENT KINDS OF INK MIXTURE IN THE INK TANK

The different ink could have been mixed due to the ink refilling mistake. If the printing quality issues occur, maybe it is the ink mixture mistake and refer to the following details.

Different kinds/Different colors ink mixture mean as bellow. Different kinds: Mix pigment Black ink with dye color ink. ・Head nozzles with ink coagulations. Different colors: Mix dye color ink with other dye color ink. ・Printing quality issues occur, but it doesn’t have ink coagulation.

Because the power ink flushing uses a lot of ink, the Maintenance Box will be full soon and SEC recommends that the user’s Maintenance Box is removed.

 How to handle the different kinds/different colors ink mixture.

In the case of ink mixture, the head and ink supply unit should be cleaned(Ink tank - Adapter).Both of handling procedures are shown as below.

 Replace CISS system (Ink Tank - Adapter)

1. Replace CISS system.

(See "2.1.4.3 How to remove the CISS system (p34)")

2. Remove the user's Maintenance Box and attach the new Maintenance Box.

3. Fill the CR02 into the ink tank in order to clean the printer head.

4. Execute Power ink flushing in Adjustment Program.

5. After Power ink flushing, confirm Blank printing (printed by CR02). If Blank printing can’t be confirmed, repeat Power ink flushing.

6. Discharge CR02 in Ink tank and fill the new ink into ink tank.

(See "2.1.4.4 Discharging procedure (p43)")

7. Execute Power ink flushing and confirm print quality.

removing the Printhead, take care not to let the terminal of the disconnected FFC touch the area around the section A. When reassembling the Printhead, be careful not to let the terminal of the disconnected FFC touch the area around the waste ink pad. Take care in the same way when replacing the Printer Mechanism and transferring the Printhead. If you connect the FFC to the connector with waste ink attached on the terminal, the circuit board may be short-circuited. Therefore, if any waste ink is attached on the terminal, make sure to wipe the ink off completely with a dry cloth or the like.

APG Driven Shaft

Because the disassembly/reassembly of the APG Driven Shaft should be done in a very narrow space, take care not to damage the gears of the APG Driven Shaft or APG Unit by hitting them with the edges of the frame or the like.

Install the APG Driven Shaft as follows.

1. Insert the gear of the APG Driven Sha ft int o the s pac e between the APG Unit and Main Frame Unit.

2. Insert the protrusion of the APG Driven Shaft into the hole on the Main Frame Unit.

3. Align the phases of the gear of the APG Driven Shaft and the Spur Gear 32.4 on the APG Unit, then attach the APG Driven Shaft.

3.2.2.2 Preparation

This section describes how and what to prepare for the preparation before starting the PG adjustment.

 Modification of the thickness gauges

 The Printhead of this printer has an integral structure of the Printhead Cover and

Printhead nozzle surface. Therefore, if the thickness gauge touches the nozzle surface in the same way as performed in the traditional procedure, the nozzle surface may be damaged. When performing the PG Adjustment or checking the platen gap, make sure to apply Teflon tape (Part Code: 1706715) on all the thickness gauges used for the adjustment or check in advance.

 When applying Teflon tape on the thickness gauges, make sure no bubbles or foreign

material remain under the tape.

Application procedure of Teflon tape



1. Clean the surfaces of the thickness gauge using alcohol, and make sure no dirt or contamination remains on the surfaces.

2. Apply Teflon tape on the thickness gauge as shown below.

3.2.2.3 PG adjustment procedure

When performing the PG adjustment, make sure of the following.

 Move the CR Unit by pulling the top pf the CR timing belt.  Be careful not to damage the nozzle surface of the Printhead with the thickness gauge.  When make the Printhead touch the thickness gauge, be careful not to let the Printhead

run onto the gauge.

 The standard range of the PG is the same as the predecessor (WF-7620/7610/7110 Series),

so it is necessary for this CISS model to keep the same condition of CR unit weight. If they are empty adapters, it is not the same weight of CR unit as the WF-7620/7610/7110 Series. Please make sure to keep the CR unit as below.

Adjustment of the 0-digit side

1. Loosen the screws (x4) on the CR Guide Frame and the screws (x2) on the PG adjustment cams (L/R) on both sides of the printer. (See " CR Guide Frame Assy (w/CR Unit) (p61)", Figure 3-9.)

2. Move the CR Unit in the middle of the printer, then place the 1.6 mm thickness gauge with Teflon tape applied at the position A shown in Figure 3-9.

Figure 3-9. Placement of the Thickness Gauge

3. Move the CR Unit to the thickness gauge and check if the CR Unit touches the gauge. If it touches the gauge, adjust the PG as follows. If not, go to the next step.

1. Bring the CR Unit back to the middle of the printer, and increment the PG adjustment cam on the 0-digit side

4.1 Cleaning

4.1.1 Cleaning the CR Unit

In this product, ink may be attached on the CR Unit by structure of Printhead and CR Unit. So, head short circuit may arise due to ink attachment on the terminal of the head FFC when replacing the printhead.

 This cleaning should be carried out only when replacing the printhead.  When installing the Printhead, make sure the Head FFC is not contaminated with ink

beforehand.

 Tool



Cotton swab or soft dry dust-free cloth

 Cleaning procedure

1. After pulling out the head FFC while holding the printhead from the carriage, confirm the ink attachment on the CR Unit.

2. If ink attached on the CR Unit, wipe it off with a cotton swab (or a soft dry dust-free cloth).

Epson L1455/ET-16500 Revision A

4.1.2 Cleaning the Exterior Parts/inside of the printer

This section describes how to clean the sections other than the carriage.  Instructions for cleaning

Exterior parts such as housing



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

 Inside of the printer

Remove paper dust with a vacuum cleaner.

 Rubber or plastic rollers such as an Pickup Roller used to feed paper

If 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.

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

cloudy.

 When wiping paper dust off the Pickup Roller/Middle 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.
