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.

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.

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

12. Observe the specified torque when tightening screws.

13. 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

14. 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.

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

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

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

18. 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.

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

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

21. When disassembling/reassembling this product, if you find adhesive power of the double-sided tape which

secure the parts or FFC is not enough, replace the tape with new one and attach it correctly to the specified

points where the parts or FFC should be secured.

22. Unless otherwise specified in this manual, the labels attached on the returned product should be transferred to

the corresponding attachment positions on the new one referring to the labels on the returned product.

Operating Principles Optical Sensor Control 25


2.3 Optical Sensor Control

WF-7520/7510/7010 series uses the optical sensor to control itself. The following describes the operating

principles of optical sensor control.

Control method

To ensure accurate printing, each part must be controlled to make an adequate amount (time) of movement. The

optical sensors read the amount (time) of movements as follows to printer to control it for achieving accurate printing.

1. Rotates the motors for control of the printer, and transmits drive force to the each part via the gear or the

timing belt.

2. The encoder reads the drive amount of each part from the scale one by one to printer to monitor that the part

drives for an adequate amount (time).

Controlled parts

The following table lists where the optical sensor control is used.

Note *1: See Fig. 2-1 (p22) and Fig. 2-2 (p23) for the positions of the parts.



Operating principles

The following describes the PF drive control as an example of the actual operation for the optical sensor.

The PF scale consists of light-passing and light-blocking portions on its surface, and runs through the slit between

the encoder’s light-emitting and light-receiving devices. While the printer is operating, the encoder always emits

light from light-emitting device toward the light-receiving device, and the light-receiving device detects light when

the light is transmitted through the light-passing portion of the scale, and does not detect light when the light is

blocked by the light-blocking portion of the scale. According to the counts of light-detected and non detected times,

the printer controls paper feed drive direction and amount.

When the encoder cannot read light-emitting/blocking counts correctly due to the misalignment, broken or

contaminated scale, paper jam, foreign object and increasing a load, the fatal error occurs and the printer stops.

Operating Principles Power-On Sequence 26


2.4 Power-On Sequence

This section describes the power-on sequences for this product. The preconditions are as follows.

Condition 1: Normal power-on sequence (See Table 2-6.)

Turning on the printer after turning it off without an error.

Initial ink charge has finished and every cartridge has sufficient ink.

No paper on the paper path.

The Printhead is capped with the Cap of the Ink System Assy.

The Carriage is normally fixed by the CR Lock.

Condition 2: Power-on sequence after recovering from a paper jam error (See Table 2-7.)

Turning on the printer after turning it off with a paper jam error.

There still remains paper on the paper path out of the detecting area of the PE sensor.

1. Printhead initialization

1-1.Initializes the Printhead, and checks for the fuse on the board in the Printhead.*4

2. Checking for waste ink overflow

2-1.Checks the waste ink counter if the waste ink overflow is occurring.

3. Avoiding deadlock sequence *5

3-1.The carriage moves to the 0-digit side slowly and confirms it touches the Right Frame.

3-2.The carriage slightly moves to the 130-digit side slowly.

3-3.The PF Motor rotates clockwise, and releases the CR lock.

4. Seeking the home position

4-1.The carriage moves to the 0-digit side slowly and confirms it touches the Right Frame. The position when it

touches the Right Frame is set as the origin position temporarily.

4-2.The carriage slowly moves to the CR lock set position.

4-3.The PF Motor rotates counterclockwise, and sets the CR lock.

4-4.The carriage moves to the 130-digit side slowly and confirms it touches the CR lock.

4-5.The carriage slowly moves toward the 0-digit side and reaches the CR lock set position.

4-6.The PF Motor rotates clockwise, and releases the CR lock.

4-7.The carriage moves to the 130-digit side slowly and confirms it does not touch the CR lock.

4-8.The carriage slowly moves to its home position, and the origin position is fixed.

Afterward, the carriage position is monitored according to the signals from the CR Encoder.

Note *1: The PF motor drive is not transmitted to the Pickup Roller during this power-on sequence.

*2: The rotation directions of the PF Motor are as follows.

Clockwise: Paper is fed normally

Counterclockwise: Paper is fed backward

*3: The conditions of the CR lock are as follows.

Red CR lock is set

White CR lock is released

*4: The fatal error occurs if there is a problem such as the fuse blew.

*5: Confirm that the CR lock is not get stuck in the gap of the carriage or any other parts preventing the carriage from moving.

*6: Eject paper if any.

*7: Executed when the detected temperature is under 5 oC (41oF) by the thermistor on the Printhead.

*8: The empty suction operation may occur depending on situations.

5. PF initialization

5-1.The PF Motor rotates clockwise for approximately one second.

5-2.The PE sensor detects if paper exists*6 and the PF Motor rotates clockwise for approximately 0.5 second.

6. Low temperature operation sequence*7

6-1.The carriage moves back and forth between the CR lock and the 130-digit side for two times.

7. PF measurement and PW sensor initialization

7-1.The carriage slowly moves to the 130-digit side.

7-2.The carriage moves to the VHCheck position quickly and stops; meanwhile the voltage values detected by the PW

sensor at the specified three points are recorded. At the same time, the PF Motor rotates clockwise and its load is

measured.

7-3.The carriage detects the voltage of the PW sensor at the carriage stop position (the black area at the Paper Guide

Front).

7-4.The carriage returns near its home position. At the same time, the PF Motor rotates clockwise and its load is

measured.

8. Detecting ink cartridge and initializing ink system*8

8-1.After the carriage slightly moves to the 130-digit side and checks the ink end sensor, detects the ink remaining.

8-2.The carriage slowly returns to its home position.

8-3.The carriage slowly moves to the 0-digit side to the CR lock set position.

8-4.The PF Motor rotates counterclockwise and sets the CR lock.

8-5.The carriage slowly returns to its home position.

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

of condition 1 (Table 2-6) is executed from No.6.

*2: If the paper jam error cannot be solved after repeating the power-on sequence on condition 2 (Table 2-7) twice, the printer turns

into the paper jam fatal error for the third time.

3.1.4 FAX Troubleshooting (WF-7520/7510 series only)

3.1.4.1 FAX Log

When an error related to fax occurs, it is not only indicated on the LCD but also saved as a log file. The error

code is recorded in it, and according to this log, the contents of the error can be confirmed.

Note *1: The latest communication log for all destinations are printed in a list form when the sequential broadcast is executed. Cancellation is treated as

a normal termination, therefore, if it is cancelled, the latest log is printed when the auto print setting is “always print”, and not printed when the

setting is “only when an error occurs”. If “only when an error occurs” is selected, the log is printed even when an error occurs for just one

destination.

*2: The power failure log when the sequential broadcast is being executed is not printed for the destinations to which the transmission log is already

complete then. If the power failure occurs before the scheduled sending time when a broadcast is scheduled, the scheduled sending time is

recorded.

Note *: For error codes, see Table 3-6. Error Code List (p.38).

Nonvolatile memory

Power failure log*2

(Fax Log)

The information stored in this log is the same as the communication log. However, since the

airtime is “Unknown” in this case, the result of it is recorded as “power failure”.Nonvolatile memory

The communication log is not stored under the following conditions:

When the sending operation is canceled while storing B&W image or waiting for

redialing.

In the case of a power failure during the operation of sending/polling reception including

waiting status for redial, or during receive operation.

When the receiving operation is canceled before the fax signal is detected.

If the fax signal is not detected during receiving operation.

If cancelled during the sequential broadcast.

(The log for the destinations of “not dialed yet” or “waiting for re-dial” is not saved except

for those of which the communication is complete.)

3.1.4.2 Error Code/Superficial Phenomenon-Based Troubleshooting

This section explains the troubleshooting procedures based on the error codes and superficial phenomenon.

When an error occurs, it may be displayed on the LCD panel with a message instead of

an error code. To check the error code, print out a fax log.

If the problem is not solved even after carrying out the remedy shown in the Table 3-8,

print out a protocol trace to analyze the cause of the error.

CHAPTER 5

ADJUSTMENT

Adjustment Required Adjustments 69


5.1 Required Adjustments

The table from the following page lists the required adjustments depending upon the parts being repaired or

replaced. Find the part(s) you removed or replaced, and check which adjustment(s) must be carried out.

If the EEPROM data cannot be read out from the old Main Board using the Adjustment Program when replacing the Main Board is required, the Waste Ink Tray Assy must be replaced with the Main Board at the same time.

After all required adjustments are complete, use the “Final check pattern print” function

to print all adjustment patterns for final check. If you find a problem with the printout

patterns, carry out the adjustment again.

When replacing the Main Board and the Printer Mechanism (Frame Base Assy) at the same time, the adjustment should be made after performing the initial setting.


• WF-7520 series: Epson WF-7525/Epson WF-7521/Epson WF-7520

• WF-7510 series: Epson WF-7515/Epson WF-7511/Epson WF-7510

• WF-7010 series: Epson WF-7018/Epson WF-7015/Epson WF-7012/Epson WF-7011/

Epson WF-7010

The table items and marks used in the “Required Adjustment List” provided on the

following pages have the following meanings.

• “O” indicates that the adjustment must be carried out.

• “---” indicates that the adjustment is not required.

• The “Mechanism Adjustment” should be performed just after reinstalling or

reassembling the part or unit. (See “Table 5-1 Required Adjustment List (Mechanism

Adjustment) (p70)”.)

• The “Adjustments using the Adjustment Program” need to be performed after

reassembling the printer completely. (See “Table 5-2 Required Adjustment List

(Adjustment using the Adjustment Program) (p71)”.)

If you have removed or replaced multiple parts, make sure to check the required

adjustments for the all parts. And when multiple adjustments must be carried out, be

sure to carry them out in the order given in the “Priority” row.

Adjustment Required Adjustments 70


Note 1: The mechanism adjustment is not necessary for the parts which are not mentioned above.

2: After the mechanism adjustment is performed, make sure to execute the adjustment using the Adjustment Program.

(See “Table 5-2 Required Adjustment List (Adjustment using the Adjustment Program) (p71)”.)

Adjustment Details of Adjustments 75


5.2 Details of Adjustments

This section provides adjustment procedures for which explanation in details is necessary. See “5.1 Required

Adjustments (p69)” for the adjustments not explained here.

5.2.1 PF Timing Belt Tension Check

This section describes PF Timing Belt tension check.

Tools

Sonic tension gauge

Plastic tweezers

Adjustment procedure

1. After installing the PF Timing Belt (p 62), rotate the PF Roller one turn.

2. Set the following parameters to the sonic tension gauge:

Weight: 1.1 g/m

Width: 3.0 mm

Span: 73 mm

3. Bring the microphone of the sonic tension gauge close to the upper center of the PF Timing Belt as shown in

Figure 5-1.

4. Press the “MEASURE” button of the sonic tension gauge and flip the PF Timing Belt with plastic tweezers

and measure the tension of the belt three times.

5. Check if all measured values fall within the standard range.

Within the standard range:

PF Timing Belt tension check is complete.

If any of the measured value is out of the standard range:

1. Loosen the screws (x2) of the PF Motor Plate, and adjust the position referring to Figure 5-1.

2. Tighten the screws of the PF Motor Plate, and measure the tension again.

Figure 5-1. PF Timing Belt Tension Check

This printer is designed so that each tension of the PF Timing Belt falls within the expected range if you correctly reassemble the unit according to this manual. If the result does not fall within the standard range when measuring the belt tension in this section, adjust it according to the instructions in this section.

The standard tension range of the PF Timing Belt is as follows:

• Standard: 13.5 ± 1.5 N

When performing the PF Timing Belt tension measurement, make sure of the following.

Perform PF Timing Belt tension measurement before installing the Main Board.

Bring the microphone of the sonic tension gauge within 5 mm from the PF Timing Belt but do not let it touch the belt.

5.2.2 Checking the Platen Gap

This section describes the procedure for checking the platen gap (PG) necessary when removing the Printhead or

in a similar case.

Tools

Thickness gauge: 1.5 mm (x2), 1.9 mm (x2)

Checking procedure

1. Move the Carriage Assy to the center of the printer.

2. Place the thickness gauges (1.5 mm) on the positions shown below.

Figure 5-2. Position of the Thickness Gauge

3. Pull the CR Timing Belt to move the CR Unit to both ends and confirm the CR Unit does not touch the

thickness gauges. If the CR Unit comes in contact with the thickness gauges, the PG is smaller than the

standard value, therefore, check if the unit is correctly reassembled. If not, reassemble the unit and perform

PG check again. (If the unit is correctly reassembled, replace the unit with a new one.)

4. Move the CR Unit to the center, and replace the thickness gauges (1.5 mm) with the thickness gauges

(1.9 mm) on the same positions as Step 2.

5. Pull the CR Timing Belt to move the CR Unit to both ends and confirm the CR Unit touches the thickness

gauges. If the CR Unit does not come in contact with the thickness gauges, the PG is greater than the standard

value, therefore, check if the unit is correctly reassembled. If not, reassemble the unit and perform PG check

again. (If the unit is correctly reassembled, replace the unit with a new one.)

This printer does not have any PG adjustment mechanism, however, it is designed so that

the platen gap can fall within the expected range if you correctly reassemble the unit

according to this manual. If the PG does not fall within the standard range after

performing the platen gap check described in this section, first check if the unit is

correctly reassembled following the instructions in this manual. Even if the unit is

correctly reassembled but the PG still cannot fall within the standard range, replace the

unit with a new one.

The standard range of the PG is as follows:

• Standard: 1.7 ± 0.2 mm

When checking the PG, make sure of the following.

Check the PG with the ink cartridges installed and the Housing Upper removed.

Move the Carriage Assy by pulling the Timing Belt.

Be careful not to damage the nozzle surface of the Printhead with the thickness gauge.

5.2.3 Scanner Timing Belt Tension Check

This section describes Scanner Timing Belt tension check.

Tools

Sonic tension gauge

Plastic tweezers

Measurement procedure

1. Move the Scanner Carriage to the 0-digit side.

2. Set the following parameters to the sonic tension gauge:

Weight: 1.0 g/m

Width: 2.5 mm

Span: 527 mm

3. Bring the microphone of the sonic tension gauge close to the center of the Scanner Timing Belt as shown in

Figure 5-3.

4. Press the “MEASURE” button of the sonic tension gauge and flip the Scanner Timing Belt with plastic

tweezers and measure the tension of the belt three times.

5. Check if the average of the measured three values falls within the standard range.

Within the standard range:

Scanner Timing Belt tension check is complete.

Out of the standard range:

1. Reinstall the Scanner Carriage, and measure the tension again.

2. If the result does not fall within the standard range, replace the torsion spring 43.6 with a new one and measure

the tension again. (p 62)

Figure 5-3. Scanner Timing Belt Tension Check

This product is designed so that each tension of the Scanner Timing Belt falls within the

expected range if you correctly reassemble the unit according to this manual. If the result

does not fall within the standard range when measuring the belt tension in this section,

reinstall or replace the related parts according to the instructions in this section.

The standard tension range of the Scanner Timing Belt is as follows:

• Standard: 3.95 ± 1.15 N

When performing the Scanner Timing Belt tension measurement, make sure of the following.

Perform Scanner Timing Belt tension measurement before installing the Scanner Housing Upper Assy.

Bring the microphone of the sonic tension gauge within 5 mm from the Scanner Timing Belt but do not let it touch the belt.

Flip the Scanner Timing Belt as weak as the sonic tension gauge can measure it.

Be careful not to damage the Scanner Timing belt when flipping it with the plastic tweezers.

When flipping the Scanner Timing Belt, be careful not to let the grease attach to it.

5.2.4 MAC Address Setting

Setting procedure

1. After replacing the Main Board, note down the MAC address written on a label on the Shield Plate Lower.

2. Reassemble the printer, and connect the printer and the PC with the USB cable.

3. Start the Adjustment Program.

4. Select the “Initial Setting” from the menu. The initial setting screen appears.

5. Enter the last six digits of MAC address into the MAC address entry field, and click the MAC Address input

button. (Enter the address again into the second entry field to confirm it.)

6. Select the network status sheet from the printer’s control panel, and print the sheet. Check the MAC address

printed on the sheet to see if it is correct.

Figure 5-5. MAC Address Setting Screen

This setting is not necessary when the data in EEPROM on the Main Board can be read out.

To avoid a conflict of MAC address on a network, make sure to correctly follow the MAC

address setting flowchart given on the following.

The user should be notified of the change of MAC address because of the following

reasons.

• If the user has set the printer’s MAC address on a router, the repaired printer with a

new MAC address cannot be connected to the network.

• The default printer name on a network consists of “EPSON” and the last six digits of the

MAC address. Therefore, the printer name becomes different from the previous one.

You are required to enter the last six digits of the MAC address (xx:yy:zz) on the

Adjustment Program.

MAC address example: 00:00:48:xx:yy:zz

(“xx, yy, zz” represents a value unique to each printer)

CHAPTER 6

MAINTENANCE

Maintenance Overview 80


6.1 Overview

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

6.1.1 CleaningExcept for the printhead, there are no other mechanical parts or units that require periodic cleaning. However, if

need arises, clean the component observing the following instructions.

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.

6.1.2 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 "6.2 Lubrication Points and Instructions (p81)" 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

Note *: Use tools whose specifications are specified in "6.2 Lubrication Points and Instructions (p81)".

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.
