EPSON Stylus COLOR 200 / EPSON Stylus 200 Operating Principles

2.1 OVERVIEW

Since the printer mechanism of the EPSON Stylus COLOR 200 is the same as for the EPSON Stylus COLOR IIs, this section only describes the differences in electrical circuitry.

2.1.1 C199 MAIN BOARD

The main control board for the EPSON Stylus COLOR 200 is the C199 MAIN board. The major difference between the electrical circuitry of the C199 MAIN board and C160 MAIN board (used in the EPSON Stylus COLOR IIs) is that the new board incorporates a new CR drive circuit. The figure below shows a block diagram of the C199 MAIN board circuitry.

2.1.1.1 Carriage Motor Driver Circuit

Carriage motor driver IC UDN2917EB (IC8) outputs a constant current to drive the carriage motor. CPU M3772152BFP (IC2) determines the motor phase and speed, and then sends a signal to the UDN2917EB carriage motor driver IC (IC8) via a 4-bit signal transmission line. The carriage motor is controlled by a 2W1-2 phase drive method. The figure below shows the carriage motor driver circuit block.

4.1.1 Bi-D (Bidirectional Printing) Alignment Adjustment

The bidirectional alignment adjustment is required when the printer mechanism, main board, or printhead (or printhead board) is replaced. Performing this adjustment determines the compensation value needed to rectify any deviation in the print position. This deviation could be caused by the different print speeds, which are due to tolerances in the mechanical components, or to differences in print timing between odd-numbered lines and even-numbered lines in bidirectional printing. The printer stores the compensation data in the EEPROM on the C199 MAIN board and refers to this data when performing bidirectional printing.

Bidirectional Adjustment is Necessary

❒ After replacing the C199 MAIN board. ❒ After replacing the printer mechanism. ❒ After disassembling the printer mechanism (for example, to replace the carriage motor). ❒ After replacing the printhead.

Adjustment Procedure

1. Connect the printer to the PC, and load paper in the printer.

2. Run adjustment program CLR200.EXE on the PC. Then, follow the program instructions, and select the Bi-D alignment operation.

3. Choose the type of head currently installed in the printer. The printer prints a Bi-D pattern with the current value.

4. Refer to the printed alignment check pattern, and specify the compensation value.

❒ To shift the even-numbered line to LEFT: Input (–) value. ❒ To shift the odd-numbered line to RIGHT: Input (+) value.

4.1.2 Head Angle Adjustment

The adjust lever on the carriage unit calibrates the printhead mounting position on the carriage unit. You must adjust the position of this lever properly to compensate for deviations in the carriage unit and the printhead.

Head Angle Adjustment is Required

❒ After replacing or disassembling the carriage unit. ❒ When a blank space (white line) is visible between the dotted lines printed by adjacent dots within

single print pass.

Adjustment Procedure

1. Run adjustment program CLR200.EXE, and select Head Angle Adjustment. Then follow program instructions.

2. Check the pattern printed by the printer. If the alignment is not correct, as shown in the figure below, change the position of the adjust lever on the carriage unit.

❒ To move the reference line UPWARD: Move the lever to the FRONT. ❒ To move the reference line DOWNWARD: Move the lever to the REAR.

Figure 4-2. Angle Lever Operation

3. When the adjustment is complete, return to the program’s main menu, and turn the printer off.

4.1.3 Zig-Zag Adjustment

If a vertical line (for example, the vertical strokes of the character “H”) is jagged, adjust the deviation in the print timing control to align the printed dot properly on the paper.

1. Run the adjustment program CLR200.EXE, and select Zig-Zag Adjustment.

2. Check the printed pattern. If it is jagged, enter an appropriate adjustment value and confirm the pattern.

3. When the adjustment is complete, return to the main menu, and turn the printer off.

4.1.5 EEPROM Reset Procedure

Like other EPSON ink jet printers, this printer is equipped with an EEPROM on the main board. This EEPROM stores status information and ink system management parameters. Since the ink system status is unique to each printer mechanism (and the printhead or ink cartridge installed), the information stored in the EEPROM must be consistent with the printer mechanism actually connected to that board. This section provides the procedures to maintain the consistency of the ink status during repair of the printer.

Table 4-3. EEPROM Operation

Service Performed Operation Required

❒ If the printer still works:

After replacing the C199 MAIN board.

Refer to Section 4.1.5.1

❒ If the printer does not work:

Refer to Section 4.1.5.2

After replacing the ink cartridge with a new one (without encountering an Ink End Error).

After replacing the waste ink pad (without encountering a Maintenance Error).

After replacing the printhead with a new one. Refer to 4.1.5.3 Printer indicates a Maintenance Error. Refer to 4.1.5.4

Refer to 4.1.5.3

Refer to 4.1.5.4

4.1.5.1 Writing Data to the EEPROM

If the main board needs to be replaced (even if it still works correctly), you need to print out all the data stored in the current EEPROM and write and save the settings to the EEPROM on the new board. This is particularly important to maintain consistency in the status information stored in the EEPROM and the actual status of the printer mechanism.

1. Run adjustment program CLR200.EXE, and select EEPROM Data Manipulation from the main menu.

2. Choose EEPROM DATA DUMP from the sub menu. The printer prints a dump of the data stored in the EEPROM.

3. When the dump print is complete, choose EEPROM DATA RESTORE from the sub menu and input all data printed out. If an EEPROM address is shown on the PC as “—-,” it is a reserved address and no data input is necessary.

CAUTION

❒After completing the operation above, perfrom the Bi-D Alignment and Zig-Zag adjustments.

Rev. A 4-5

Adjustments EPSON Stylus COLOR 200 / EPSON Stylus 200

4.1.5.2 EEPROM Initialization for Main Board Replacement

If the main board malfunctions and is unable to read out the contents of the EEPROM, replace the main board with a new one, and follow the steps below.

1. Replace the ink cartridge currenly installed on the printhead with a new one.

2. Replace the waste ink pad with a new one.

3. Reset user setting parameters (see Table 1-13 in Chapter 1).

CAUTION

❒Perform the Bi-D Alignment and the Zig-Zag adjustments. ❒Never perform the EEPROM clear operation described in Table 1-13 of Chapter 1, because it

clears all data stored in the EEPROM, including parameters definable only at the factory.

4.1.5.3 Ink System Initialization

If you replace the ink cartridge or printhead during repair, you must also initialize the ink system status stored in the EEPROM. Since the ink system is managed using status information stored in the EEPROM (i.e., ink consumption, number of flushing operations, etc.), status information becomes inconsistent if you replace the ink cartridge or the printhead without initializing the ink system, and this can cause incorrect error indications or ink system malfunctions.

1. Replace the ink cartridge or the printhead with a new one.

2. Run adjustment program CLR200.EXE, and select EEPROM Data Manipulation from the main menu.

3. If you replaced the ink cartridge, choose INK COUNTER CLEAR from the sub menu, or if you replaced the printhead, choose INITIAL-CHARGE FLAG RESET.

4.1.5.4 Maintenance Error Clear

The ink system monitors the amount of unused ink discarded to the waste ink pad, and when the amount reaches a predefined limit, the printer warns the user by indicating a Maintenance Error. This means the waste ink pad needs to be replaced. If the waste ink pad needs to be replaced, whether or not a Maintenance Error is indicated, follow the steps below to clear the error.

1. Replace the waste ink pad with a new one.

2. Turn the printer off.

3. Turn the printer on while holding down the LOAD/EJECT and CLEANING buttons on the control panel. The Ink End and Paper Out LED lamps start blinking.

4. When these LED lamps start blinking, press the LOAD/EJECT button within 3 seconds and hold it down for 10 seconds or more.

5. Then press the CLEANING button to execute the Maintenance Error Clear operation.

CAUTION

❒Be sure to replace the waste ink pad with a new one.

Epson Stylus Color 200 /Epson Stylus 200 Troubleshooting

5.1 OVERVIEW

This section describes troubleshooting at the unit level and for abnormal printing(missing-aligned dots). The EPSON Stylus Color 200/Epson Stylus 200 uses a new print head that is different from the previous Stylus Color print head. Because of its designs, the status monitor indicates when the cartridge is low or out of ink. If you remove or even partially remove a cartridge unit before it is out of ink, air invades the print head nozzle(s) and the ink cartridge. Once air bubbles clog the nozzle(s), they are very difficult to eliminate. Refer to the Section 5.5 to attempt to clear clogged nozzle(s).

CAUTION

The ink out sensor on the printer is monitored by the firmware counter. If you replace an ink cartridge before its ink sensor is activated, you must clear the EEPROM first.

5.5 Dot missing Trouble shooting Guide

This section describes how to recover the clogged nozzle when you receive the dot-missing printer. Since the print head of this printer is the new system, it is very difficut to eliminate the invaded air bubble from the print head unit or the ink cartridge so that, never use again if you remove once a ink cartridge from the main unit. Also, we prepair the special ink cartridge exclusive for your service side. Please refer to the following table for low price ink cartridge.

Table 5-6. Ink Cartridge exclusive for the service side

Ink Cartridge Code

Black ink cartridge 1023206 Color Ink cartridge 1029341

WARNING

❐Do not re-use a removed ink cartridge when you return the printer to your user. ❐Since the ink end sensor is counted by the firmware counter, there is a possibility that “Ink low”

or “Ink out” error indications might appear. Therefore, make sure to reset the EEPROM (firmware counter) after the ink cartridge is replaced. Also, the waste ink drain pad should be replaced according to its conditions.

CAUTION

❐Only when the printhead is installed for the first time, indiviual dummy CL sequences for black and color head need to be done initial charge. However, once initial charge is done, it can not be done unless the inital charge flag in the EE-PROM is reset. Therefore, either perform this initial charge by using adjustment program or reset the EEPROM by the panel operation. It is encouraged to use the adjustment program sicne the panel reset requires additional adjustmens. ❐There are two reset methods to clear the EEPROM. Select a proper method according to the following conditions.

*Maintenance error status: Reset by the panel

*Normal status (No-error status): Reset by the adjustment program

5.5.1.3 Performing the CL operation for 2 ~ 3 times

This section describes the cleaning operation if you find a print missing on the 360-DPI check pattern. You need a confirmation either the CL opeartion is correctly performed or not in this function..

[Step1] Perform the CL operation. (Under the pause state, pressing the Clening button) [Step2] Pay attention to the sponge in the cap either the ink is correctly supplied or not ( In case of color

head installed, the color of YMC becomes clear from the right side. In case of black head installed, the sponge becomes black evenly.)

[Step3] If an ink is not correctly supplied, check the under items before you advance to next step

before going to the next step on the main flow chart.

■ Observing the cap from above, make sure there are not any bents , holes or scars on the surface.

Note:

If you can not find any problems about the pump unit system or the above contents, there is a possibility that an ink in the ink cartridge has already emptied in spite of any counter values, so that it is necessary to replace to the brand-new ink cartridge Also, if user perform removing or installing with the same ink cartridge, it will not recover the dot-missing every time you perform the CL operation, because the constructure of the print head is very complex as compair to previous head system. Therefore, replace to the brand-new ink cartridge at this time.

5.5.1.4 Is the Head angle correct?

This section describes either the head angle condition is correct or not. Refer to Section 4.1.3 for the acrual adjustment.

[Step 1] Perform the head angle adjustment. (Refer to Section 4.1.3.) Note: If the head angle condition is wrong, white or color banding problem will be appeared on the

graphic pattern.

5.5.1.5 Initial charge operation

Since the status, whether the initial charge operation has been performed or not, is stored in the EEPROM, you have to clear this with the adjustment program to perform the initial charge operation again on the same printer.

[Step 1] Execute the adjustment program “CLR200.EXE” and select “EEPROM Data Manipulation”. [Step 2] Choose “INITIAL-CHARGE FLAG RESET” from the sub menu. [Step 3] Install new printhead and new ink cartridge on the printer. Then turn the printer on to

start the initial-charge operation.

5.5.1.6 Replace to new ink cartridge

It is necessary to replace the print head unit if you can not recover alogged nozzle by performing the initial ink charge, CL operation and replacing the new ink cartridge. If you replace to new ink cartridge, do not re-use a removed ink cartridge again.

Epson Stylus Color 200 /Epson Stylus 200 Maintenance

6.1 PREVENTIVE MAINTENANCE

This printer must be lubricated only O-11 when you need a lubrication for carriage guide shaft. If you lubricate with another oil, it could permanently damage the print head unit.. Although this printer requires no specific maintenance on a regular basis, recommends that you clean the following thoroughly whenever you get a chance.:

❏ Outer case

Use a soft, clean cloth, dampened with mild detergent, if necessary.

❏ Auto sheet feeder

If the inside of the auto sheet feeder is dirty (dusty), carefully brush away all dust and dirt using a soft brush. If the pickup roller of the sheet feeder is dirty, clean its surface with a soft, clean cloth.

❏ Inside the printer

If you notice any dust or dirt that has accumulated inside the printer when you open the outer case for repair, remove all dust and dirt using a small vacuum cleaner designed for such purposes.

WARNING

❏ Use only O-11 oil when lubricationg the carriage guide shaft. If you lubricate with another oil, it could permanently damage the print head unit. ❏ Never use paint thinner, trichloroethyylene, or ketone-based solvents for cleaning. These chemicals can damage the components the printer.

❏ Do not use a hard or abrasive brush for cleaning. ❏ Be careful not to damage the components of the printer when using a vacuum cleaner. ❏If ink gets into your eyes, flush them immediately with clean water and ask for medical attention. ❏Disconnect the printer from the power source when you clean inside the printer.

CAUTION

❏Once removed ink cartridge must be replaced to the brand-new cartridge when the printer is sent back to the user.(Regfer to the following ink cartridge code)

●Black: 1023206 , Color: 1029341 ❏When the printer is sent back to the user or during the transport, the cartridge should remain to

be installed in the main unit. Since protective material is required to protect carriage during the transport, it should be ready for avilability. ❏It is encouraged to use the adjustment program to adjust the head angle and location when the print head is replaced.

6.1.1 Printhead Cleaning

If print quality deteriorates, clean the printhead using the built-in printhead cleaning function. The printer also has an automatic printhead cleaning cycle to ensure proper nozzle operation for ink ejection and to preserve the printhead in the best condition. Performing the cleaning more often wastes ink.

1. Turn the printer on and press the Cleaning button. The Power light flashes during this cycle and then stays on when it is finished.

2. Turn off the printer.

Rev. A 6-1

Maintenance Epson Stylus Color 200 / Epson Stylus 200

3. Hold down the Load/Eject button as the printer is turned back on. This prints a demonstration page in order to check the result.

4. Turn off the printer to exit demonstration mode.

CAUTION

If the cleaning operation is performed more than 4 times continuously, ink is not absorbed because of dummy CL sequence function. Threfore, if cleaning operation is required more than 4 times, it should be restarted after printing something out once, such as self-test or demonstration page.

6.1.2 Waste Ink Drain Tank Replacement

The printer counts the total amount of ink drained to the waste ink tank, and this information is stored in the EEPROM on the main board (Protect counter A) for ink system operation management. If the value of this counter reaches a predetermined value, all three lights blink and indicate error status. (“Maintenance request,” see Chapter 1, Error indications, Table 1-15). When this error is displayed, replace the waste ink drain pad and reset the protect counter.

1. Remove the printer mechanism (Refer to3.2.5) and replace the waste ink tank located in the waste ink

tank.

2. After reassemble the printer, take following steps in order to reset the protect counter.

3. ➮ Turn the printer on while holding down the Clening and Load/Eject buttons.

➬ Within 3 seconds after ➮ prcedure, hold down Load/Eject button for 10 seconds.(until Ink out and Paper out lights start blinking)

4. Under this condition, press the Cleaning button, then initialize operation will be automatically

perforemed.

CAUTION

❐Since the value of conater is stored in EEPROM, the waste ink pad must be replaced when the main board is replaced. Ohterwise, ink might leak from the waste ink tank while printing.
