Product Description 1.4 OPERATIONS This section describes the basic operations of the printer. 1.4.1 Control Panel The control panel for this printer has 2 non-lock-type push buttons, and 3 LED indicators for easy operation of the various printer functions. Power Paperout...
Product Description 1.4.3 Default Settings The printer can save some printer setting parameters that define its functions at initialization. You can change these parameters using the printer’s default setting mode. 1.4.3.1 Default Setting Items You can use default setting mode to change settings listed in the table below. Activate default-setting mode by holding down the Load/Eject and Cleaning buttons while turning on the printer.
User is requested to operate 2 buttons watching 3 lights on the control panel. The lights turn on and off, and blink in one or the patterns described in the guidance sheets (language selection sheet and printer setting sheet) which are printed out at first in the setting mode. Please refer these sheets for the feature and character selection.
Product Description 1.4.4 Error Conditions The printer can detect various errors and indicate them with LEDs. Refer to Table 1-14. 1.4.5 Printer Initialization There are three initialization methods: power-on initialization, software initialization and operator initialization. 1.4.5.1 Power-On Initialization This initialization of this level is activated by power-on or cold-reset command(remote RS command).
Epson Stylus Color 200 /Epson Stylus 200 1.5 MAIN COMPONENTS The main components of the Stylus Color IIs are: Printer mechanism (M-4C11) Main control board (C199 MAIN Board) Power supply unit (C160 PSB/PSE Board) Control panel board (C160 I/F Board) Housing 1.5.1 Main Control Board (C199 MAIN Board)
The power supply board (C160 PSB/PSE Board) consists of an RCC switching regulator circuit. This board does not have a power switch connected to the secondary circuit like the Stylus Color series. Thus, if the printer is turned off, it cannot continue to operate in order to perform the head capping operation.
Figure 1-11.M-4C11 Printer Mechanism 1.5.5 Housing The Epson Stylus Color 200/Epson Stylus 200 housing consists of the printer cover, upper case, and lower case. Attached to the housing are the front paper support and ejected paper support with paper separator.

EPSON Stylus COLOR 200 / EPSON Stylus 200 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.
Make specified adjustments when you disassemble the printer. (See Chapter 4.) 3.2 DISASSEMBLY AND ASSEMBLY This section consists of the subheads shown in the diagram below. See the exploded view of the printer in the Appendix, if necessary. Follow the precautions in Section 3.1.1 when disassembling the printer.

EPSON Stylus COLOR 200 / EPSON Stylus 200 4.1 OVERVIEW This section describes adjustments required when the printer is disassembled and assembled for repair. After removing an ink cartridge, always install a new cartridge immediately. During adjustments and testing, use cartridges designed exclusively for service :...
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.
Run adjustment program CLR200.EXE, and select Head Angle Adjustment. Then follow program instructions. 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.
Remove the upper case, and place a thickness gauge (commercially available) on the paper guide plate at the adjustment position on the left side of the printer, as shown in the figure below: Move the carriage unit manually onto the thickness gauge.
EPSON Stylus COLOR 200 / EPSON Stylus 200 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.
Page 54
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.

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.

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.

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 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.
Page 69
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.
The printer must be lubricated properly when it is disassembled for component replacement, or if mechanical noise exceeds a certain level. EPSON recommends only the lubricants listed in table below for this printer. They have been tested extensively and found to comply with the requirements of this printer mechanism.
