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 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.

1.3 Unit Level Troubleshooting

You can identify the troubles by using the checklist in this section after confirming the LED/LCD indication on the control panel or the error message displayed on STM3 of the PC connected to the printer. As a result, you can save the whole repair time. When finding any faulty parts, refer to Chapter 2 "ASSEMBLY/DISASSEMBLY" and replace them. Following tables describe the error conditions (LED/LCD and STM3) and their possible cause.

The following is the example of how to use the tables. Example) When "Carriage Unit" is out of the home position at the power on timing,

the Fatal Error may be caused by the failure of "CR Motor". Moreover, there are 3 possible causes on "CR Motor" failure.

(Note) When individual part that makes up "Roller EJ Assy.", "PF Motor" and "Ink System Assy." is defective, replace the Printer Mechanism with a new one basically. However, if an individual part needs to be replaced urgently, execute the necessary operation by referring to Chapter 2 "ASSEMBLY/DISASSEMBLY".

Check Point Remedy

1. Connect "Power Supply Board cable" to the CN2 on "Main Board".

2. Replace "Power Supply Board" with a new one.

EPSON Stylus Photo R200/R210 Revision A

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

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

o Caution for disassembly/assembly of Printer Mechanism

1. "Printer Mechanism" with "Housing, Lower"

• Do not hold "Guide Plate, CR" Þ Transforming of "Frame, Main" and "Guide Plate, CR" may give some bad influence to PG or printing.

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

2. "Printer Mechanism" without "Housing, Lower"

• Manage the standard values for installation. (See below)

• First, remove "Support Plate, Frame, Main". Then, remove "Roller PF Unit", "Roller EJ Assy." and "Paper Guide, Front".

• Make sure to manage "Waste Ink Tube".

• Be careful with the interconnection of "Star Wheel/CDR Sensor" connector cable.

• Assemble "Cam, CR, Left" while gearing with the APG gear.

n Management of the reference position for installation

[Reason] Accurate installation for each comp onent of "Prin ter Mechanism" is on a basis of "Housing, Lower".

[Support for Service] Check if there is no gap between "Frame, Main" and "Housing, Lower".

[Reference] In order to ensure the accuracy for installation, it is necessary to manage the reference position for installation in X, Y and Z direction.

[X-axis direction]

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

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

[Y-axis direction]

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

[Z-axis direction]

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

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

n Management of the perpendicular accuracy of "Guide Plate, CR" (The

standards of the guide rail's perpendicular direction is on the basis of the hooks of "Carriage Unit" and "Print Head".)

[Reason] Deformation of "Guide Plate, CR" may cause the defective print/operation.

[Support for Service] Specify the correct raising position for "Main Frame" so that it will not be deformed.

DISASSEMBLY AND ASSEMBLY Caution regarding assembling/disassembling the printer mechanism, and how to ensure the quality of reassembled product 34

EPSON Stylus Photo R200/R210 Revision A

n How to install "ASF Unit", "Main Board" and "Paper Guide, Upper"

[Reason] When installing these three components, too much force can be given to "Frame, Main", therefore, it may be deformed and cause the defective print/ operation.

[Support for Service] Hold the opposite side of the components securely, when installing them.

3. CDR Guide Assy.

n Management of the level accuracy of "CDR Guide Assy."

[Reason] Deformation of "CDR Guide Assy." may cause the defective print.

[Support for Service] Disassemble/assemble carefully "CDR Guide Assy.".

o How to secure the quality for reassembled products

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

MAINTENANCE

CHAPTER

EPSON Stylus Photo R200/R210 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 returning the printer from the user, check the following parts and perform appropriate cleaning if stain is noticeable.

C A U T I O N

o Housing

Use a clean soft cloth moistened with water and wipe off any di rt. If th e Housi n gs are stained with ink, use a cloth moistened with neutral detergent to wipe it off.

o Inside the printer

Use a vacuum cleaner to remove any paper dust.

n 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.

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

the printer.

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

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

4.1.2 Service Maintenance

If print irregularity (missing dot, white line, etc.) has occurred or the printer indicates "Maintenance Error", take the following actions to clear the error.

o Head Cleaning

If dot missing or banding phenomenon has occurred, use the 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 Progra m.

When performed by operat ing the C ont ro l Pan el, first mak e sure that the printer is in stand-by status. Then, select the cleani ng mode by pres sin g the Maintenance button on the Control Panel. The message, "Beginning head cleaning" will be displayed on LED. By pressing the OK button, the printer will start the cleaning sequence.

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

The following explanation is the 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 mode s for Manual Cleaning, and it automatically selects

the best cleaning mode in accordance with the various con ditions and perf orms the operation. Therefore, the consumption of the ink by the manual cleaning will vary according to the selected mode for the condition.

o 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 bruch or soft cloth moistened with alcohol.

MAINTENANCE Overview 87

EPSON Stylus Photo R200/R210 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. If repeating the Print Head cleaning operation without choosing "Nozzle Check", CL1, the weakest cleaning, will be repeated.

o 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 = Waste Ink Pad Counter A = variable between 20000 and 46750), The Waste Ink Counter detects that the Was te 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 occurs, replace the Waste Ink Pad and res et the Waste I nk Counter set 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. Because another "Maintenance Request Error" could occur after returning the repaired product to the user, if the Waste Ink Counter is close to its limit, it is recommended that the Waste Ink Pad be replaced.
