Epson Stylus Color 200 /Epson Stylus 200 Product Description 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 main control board (C199 MAIN Board) consists of an M37721S2BP 16-bit CPU. The E05B32 gate array operates with 25MHz clock speed and controls various memories.
Product Description Epson Stylus Color 200 /Epson Stylus 200 1.5..2 Power Supply Board (C160 PSB/PSE 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.
Epson Stylus Color 200 /Epson Stylus 200 Product Description 1.5.4 Printer Mechanism (M-4C11) The M-4C10 printer mechanism is equipped with a replaceable 64-nozzle black printhead and 60-nozzle color (CMY) printhead, and it can print at a high resolution (720 dpi) using the special coated paper. 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.

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.
Operating Principles EPSON Stylus COLOR 200 / EPSON Stylus 200 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.
EPSON Stylus COLOR 200 / EPSON Stylus 200 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. Table 2-2.

EPSON Stylus COLOR 200 / EPSON Stylus 200 Adjustments 4.1 OVERVIEW This section describes adjustments required when the printer is disassembled and assembled for repair. CAUTION ❒After removing an ink cartridge, always install a new cartridge immediately. During adjustments and testing, use cartridges designed exclusively for service : Monochrome:1023206 CMY (Color):1029341 Table 4-1. Required Adjustments Service Performed Adjustment Needed After replacing the M-4C11 printer mechanism.
Adjustments EPSON Stylus COLOR 200 / EPSON Stylus 200 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.
EPSON Stylus COLOR 200 / EPSON Stylus 200 Adjustments 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.
Adjustments EPSON Stylus COLOR 200 / EPSON Stylus 200 4.1.4 Platen Gap Adjustment This adjustment is required after you have removed the carriage unit from the main unit or replaced the carriage unit. Adjust the distance between the printhead nose and the paper surface to 1.18 mm. 1. 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: 2.
EPSON Stylus COLOR 200 / EPSON Stylus 200 Adjustments 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.
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).
