CHAPTER

EPSON Stylus Photo R220/R230 Revision A

1.1 Overview

This chapter describes how to identify troubles in two levels: unit level repair and component level repair. Refer to the flowchart in this chapter to identify the defective unit and perform component level repair if necessary. This chapter also explains motor coil resistance, sensor specification and error indication.

Since CR Motor and APG Motor are DC Motors, the resistance among the electric poles varies. Therefore, judge if it is normal or abnormal based on if there is no operation of the motor or not; the resistance values cannot be used to judge the abnormality. However, it is difficult to judge accurately, if it is not clear, replace the motor.

DISASSEMBLY / ASSEMBLY

CHAPTER

EPSON Stylus Photo R220/R230 Revision A

2.1 Overview

This chapter describes the procedure for disassembling and reassembling the main components of the Stylus Photo R220/R230. 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”. “CAUTION” signals a precaution which, if ignored, could result in damage to equipment. Important tips for procedures are described under the heading “CHECK POINT”. If the assembly procedure is different from the reversed disassembly procedure the correct procedure is described under the heading “REASSEMBLY.” Any adjustments required after reassembly of components or parts are described under the heading “ADJUSTMENT REQUIRED”. When you have to remove any parts or components that are not described in this chapter, refer to the exploded diagram in the Appendix. Read the next section “Precautions” fully before starting disassembly.

2.1.1 Precautions

Before starting the disassembly or reassembly of the product, read the following precautions given under the headings WARNING and CAUTION.

W A R N I N G

 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.

 To protect sensitive microprocessors and circuitry, use static

discharge equipment, such as anti-static wrist straps, when accessing internal components.

 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 physician.

 When reassembling the waste ink pads and tray, always make

sure that the waste ink tube is fitted correctly in the specified place. Fitting the ink tube in other than the specified position can cause ink leakage.

C A U T I O N

 When transporting the printer after installing the ink cartridge,

pack the printer for transportation without removing the ink cartridge and be sure to secure the Ink Cartridge to the printer cover with tape tightly to keep it from moving.

 Use only recommended tools for disassembling, assembling or

adjusting the printer. (Refer to Table 2-1 "Tool List".)

 Observe the specified torque when tightening screws.  Use the specified lubricants and adhesives. (Refer to Chapter 4

for details.)

 Make the specified adjustments when you disassemble the

printer. (Refer to Chapter 3 for details.)

 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.

2.1.2 Recommended Tools

Use only specified tools to avoid damaging the printer.

2.2 Caution regarding assembling/disassembling the printer mechanism, and how to ensure the quality of reassembled product

For the existing Low End models, it is basically forbidden to remove the Lower Housing from the Printer Mechanism. This is because the strength of the Main Frame is not strong enough, therefore, the Main Frame may be deformed when removing/ reinstalling it from/to the Lower Housing. For that reason, when replacing the Ink System or the PF Motor, it is recommended to replace not only the Lower Housing but also the Printer Mechanism.

For this printer, it is necessary that the Lower Housing be removed from the Printer Mechanism when replacing the Waste ink Pads or the Ink System Unit. Therefore, this chapter specifies the disassembly/assembly of the Printer Mechanism which the Lower Housing has been taken out in order to secure the quality of the repaired items.

 Cautions for disassembly/assembly of the Printer Mechanism

1. the Printer Mechanism with the Lower Housing

• Do not hold the Guide Plate, CR ⇒ Deforming of the Main Frame and the Guide Plate, CR may give some bad influence to PG or printing.

• Do not touch the CR Guide Shaft and the surface of the head nozzle.

• Note that the screws that secure the Main Board is M4, not M6. If you use M6 screw mistakenly, it will interfere with the Carriage.

• Be careful not to let the damper of the CDR come off as it is secured by the Lower Housing.

2. the Printer Mechanism without the Lower Housing

• Make sure the exact attaching position in all X, Y and Z directions. See the Ensuring the attaching position in X, Y and Z directions.

• Be sure to remove the Frame Support before removing the PF Roller Unit, Roller EJ, and the Front Paper Guide.

• Be sure to confirm that The Waste Ink Tube is correctly installed.

• Be sure to route the cables of the Guide and Tray Sensor correctly.

• The APG gear must be engaged properly.

 Ensuring the attaching position in X, Y and Z directions.

Installing each part or component of the Printer Mechanism accurately can be made by determining the positions of them in relation to the Lower Housing.

[When Servicing] Check that there is no gap between the Main Frame and the Lower Housing.

[Reference] In order to ensure the accuracy of installation positions, it is necessary to make sure the positions in X, Y and Z directions.

[X-axis direction]

• Check if the Main Frame is correctly set to the groove of the Lower Housing.

• Check if there is no gap between the Main Frame and the Lower Housing.

[Y-axis direction]

• Check if the slot of the Main Frame is correctly attached to the projection of the Lower Housing.

[Z-axis direction]

• Check if there is no gap between the Main Frame and the Lower Housing.

• Check if correctly secured with the tabs (2 on the left, 1 on the right, 1 on the right front) of the Printer Mechanism.

 Maintaining the perpendicularity of the Guide Rail (The Guide Rail is secured

by the Ink Cartridge Holder and the Print Head).

Deformation of the Guide Plate, CR may cause the defective print/operation.

[When Servicing] Specify the correct raising position for the Main Frame so that it will not be deformed.

 Installing the ASF Unit, the Main Board and the Paper Guide, Upper

Forces exerted on the Main Frame when installing the three components may deform the frame resulting in a malfunction of the printer or print quality problem.

[When Servicing] Hold the opposite side of the components securely, when installing them.

3. CDR Guide Assy.

 Maintaining the levelness of the CDR Guide Assy.

Deformation of the CDR Guide Assy. may cause the defective print. [When Servicing]

Disassemble/assemble carefully the CDR Guide Assy.

 Ensuring the quality of reassembled products

It can be judged that the quality of the reassembled products is ensured if the printing test with the Adjustment program is successful.

MAINTENANCE

CHAPTER

EPSON Stylus Photo R220/R230 Revision A

4.1 Overview

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

4.1.1 Cleaning

This printer has no mechanical components which require regular cleaning except the Print Head. Therefore, when serving the printer that has been sent for repair, check the following parts and perform appropriate cleaning if stain is noticeable.

C A U T I O N

 Housing

Use a clean soft cloth moistened with water and wipe off any dirt. If the Housings are stained with ink, use a cloth moistened with neutral detergent and wring out tightly to wipe it off.

 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 the components of the printer or deteriorate the quality of the printer.

 Be careful not to damage any components when you clean inside

the printer.

 Do not scratch the surface of the PF Roller. Use a soft brush to

wipe off dust. Use a soft cloth moistened with dilute alcohol to remove 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.

4.1.2 Service Maintenance

If print irregularity (missing dot, white line, etc.) or a maintenance request error (indicated as "Service Required" by the Status Monitor) has occurred, take the following actions to clear the error.

 Head Cleaning

If dot missing or banding phenomenon has occurred, use the Print Head Cleaning function and perform the Print Head cleaning operation.* This function can be performed by operating the control panel, the print driver utility and the Adjustment Program.

When performing the cleaning sequence by operating the Control Panel, first make sure that the printer is in stand-by status. (The LED of power supply is lighting.) Then, press the [Ink] button for more than three seconds. The printer will start a cleaning sequence.

When selecting the manual cleaning by the printer driver utility, the most appropriate cleaning mode will be selected.

The following is an operation process of the printer head cleaning by the Printer Driver Utility. Refer to Chapter 3 "ADJUSTMENT" for the operation of the Adjustment Program.

* This product has three modes for Manual Cleaning, and even it is in operation,

it automatically selects the best cleaning mode in accordance with the various conditions of the printer. Therefore, the consumption of the ink by the manual cleaning will vary depending on the selected mode.

 Inside the printer

Use a vacuum cleaner to remove any paper dust.

 LD Roller

When the paper loading function does not operate because friction of the LD Roller has gone down due to paper dust, remove the dust by using a soft cloth moistened with alcohol.

MAINTENANCE Overview 96

EPSON Stylus Photo R220/R230 Revision A

1. Select EPSON Status Monitor 3 in the Printer Driver Utility. Then make sure that the printer connected to Status Monitor 3 is on standby status. If it is on standby, the following will be displayed.

Figure 4-1. Display for Status Monitor 3

2. Select Head Cleaning in the Printer Driver Utility and execute the printer Head Cleaning. After the cleaning, choose "Nozzle Check" and print the Nozzle Check Pattern.

 Maintenance Request Error

Ink is used for operations such as Head Cleaning as well as printing. In that case, the ink is drained into the Waste Ink Pad and its amount is counted in the Waste Ink Counter set in the EEPROM on the control board. When the preset value is reached (Waste Ink Counter = Protection Counter A = variable between 20000 and

46750), The Waste Ink Counter detects that the Waste Ink Pad has reached its predetermined limit. The Maintenance Request Error will be displayed on Status Monitor 3 as shown below.

Figure 4-3. Maintenance Request Error Display on Status Monitor 3

If this error occurs, replace the Waste Ink Pad and reset the Waste Ink Counter stored in the EEPROM. Resetting of the Waste Ink Counter can be done only from the Adjustment Program since this product does not have the reset function for the Waste Ink Counter through the operation Panel Switch. Refer to Chapter 3 "ADJUSTMENT" for the reset procedure. During repair service, the Waste Ink Counter must be checked according to the firmware version, the Main Board checker program version and the Nozzle Check Pattern of the Nozzle Check Pattern Print. If the Waste Ink Counter is close to its limit, we recommend to replace the Waste Ink Pad since another "Maintenance Request Error" might occur after returning the repaired product to the user.
