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.

Figure 2-2. Carriage Motor Drive Circuit Block Diagram
Motor driver IC UDN2917EB controls the motor stepping direction and drive current with a combination of six signals supplied from the CPU. PH1 and PH2 signals control the current flow direction to determine the motor stepping position; and the I10, I11 and I20, I21 signals determine the drive current supplied to each motor drive coil. Table 2-1 lists the combinations of these signals used for the 2W1-2 phase drive control.

Operating Principles
In the Table 2-1, if the control sequence is executed in incremental order, the carriage motor rotates clockwise (CW). (The CR moves from 1st column to 80th column.) Signals output from ports P105, P106, and P107 of the CPU determine the reference trip current level used by the motor driver IC for drive current control. Table 2-2 lists the connection of the output signals and the reference trip current levels.

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
Ì Ì Ì Ì 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. 2. 3. 4. Connect the printer to the PC, and load paper in the printer. Run adjustment program CLR200.EXE on the PC. Then, follow the program instructions, and select the Bi-D alignment operation. Choose the type of head currently installed in the printer. The printer prints a Bi-D pattern with the current value. Refer to the printed alignment check pattern, and specify the compensation value. Ì To shift the even-numbered line to LEFT: Input () value. Ì To shift the odd-numbered line to RIGHT: Input (+) value.

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 Ì If the printer still works: Refer to Section 4.1.5.1 Ì If the printer does not work: Refer to Section 4.1.5.2 Refer to 4.1.5.3 Refer to 4.1.5.4 Refer to 4.1.5.3 Refer to 4.1.5.4
After replacing the C199 MAIN board.
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. Printer indicates a Maintenance Error.
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. 2. 3. Run adjustment program CLR200.EXE, and select EEPROM Data Manipulation from the main menu. Choose EEPROM DATA DUMP from the sub menu. The printer prints a dump of the data stored in the EEPROM. 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
ÌAfter completing the operation above, perfrom the Bi-D Alignment and Zig-Zag adjustments.

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. 2. 3. Replace the ink cartridge currenly installed on the printhead with a new one. Replace the waste ink pad with a new one. Reset user setting parameters (see Table 1-13 in Chapter 1).
CAUTION
ÌPerform the Bi-D Alignment and the Zig-Zag adjustments. ÌNever 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. 2. 3. Replace the ink cartridge or the printhead with a new one. Run adjustment program CLR200.EXE, and select EEPROM Data Manipulation from the main menu. 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. 2. 3. 4. 5. Replace the waste ink pad with a new one. Turn the printer off. 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. When these LED lamps start blinking, press the LOAD/EJECT button within 3 seconds and hold it down for 10 seconds or more. Then press the CLEANING button to execute the Maintenance Error Clear operation.
CAUTION
ÌBe sure to replace the waste ink pad with a new one.
