sty/ua Cubf S9wke Manual Opfating Pfincipies 2.2.1 Printer Mechanism The printer mechanism of this printer uses a dropmnde-d inkjet system similar to the system used on all other EPSON ink jet printers. However, the printhead in this system is mmpletely redesigned to make it more mmpact and ensure a high level of reliability. The figure below shows the structure of the printhead and ink supply system. ■ M-L-P MLP is the abbreviation for Multi-Layer Piezoelectric element.

Sryhs color Sewka #anuaf Op9mthg Principks The Stylus Color printer has a special printing mode, called microwave mode, for printing raster graphics. This printing mode can be selected from the custom driver. Using the microwave mode can improve the quality of output because it elimina tes the banding that can sometimes Occurin normal mode. In microwave mode, the paper feed ogration is performed after each print pass, thus eliminating the pitch variation as the paper feed that causes the banding.

Operating Principles Sty/us Color Service Manual 2.3.2 Operating Principles of the Main Control Circuit The main control circuit of this printer is the C137 MAIN board. This circuit is controlled by the 16-bit CPU H8/3003 (ICI), running at 14.7456 MHz. This CPU has a unique architecture capable of handling data on the data bus at either an 8-bit or 16-bit bus width. Because of this, a 16-bit or 8-bit data bus width-type ROM is used on this board, increasing the internal processing speed.

Sty/us Cc#of &mdce Manual Opemting Principles 2.3.2.1 Reset Circuits The C137 MAIN board contains 2 reset circuits: the +5V monitor reset circuit and the +35V monitor reset circuit. The +5V monitor reset circuit monitors the voltage level of the +5V line, using reset IC PST592D (IC12), and outputs a reset signal to the E05A96 gate array (IQ when the voltage level drops below +4.2V.

Operating Principles Sty/us Color service Manual 2.3.2.3 Carriage Motor Drive Circuit The carriage motor drive IC SLA7041MS (IC15) outputs a constant current to drive the carriage motor for the printer mechanism. Gate array E05A96EA (IC2) decides the motor phase and speed and then sends a signal to the carriage motor driver IC (SLA7041MS) using the 4-bit serial transmission line. The first bit indicates the direction of the motor rotation.

Adjustments Stvlus Co/or Sewkw Manual 4.1 OVERVIEW This section describes the adjustments that are required when the printer is disassembled and assembled after repair. Since this printer has both the black head and color head, it needs new adjustments not required fix previous printers. Perform the suitable adjustments by referring to the following table. ■ The adjustments must be performed in the order indicated. Always follow the correct order.
PAGE 82
Stylus Color Service Manual Adjustments 4.1.1 Destination Data Writing Operation The setup value that specifies the destination setting is stored into the EEPROM on the C137 MAIN board. Therefore, this setup value must be written into the EEPROM when the MAIN board or the EEPROM chip is replaced. r.. . 1. Comect the PC to the target printer and turn the printer on. 2. Execute BASIC on the PC and runtheprogram “VERxxx.BAS”. 1. Destination Setting 2.

Adjustments Stylus Color Service Manua/ 4.1.2 Bi-D (Bidirectional Printing) Alignment Adjustment The bidirectional alignment is required when the printer mechanism, the MAIN board, or the printhead (board) is replaced. By perfo rming this adjustment, a compensation value is determined to compensate for the deviation in the print position.
PAGE 84
Stylus Color sefv~ce #?hnua/ Adjustments 4.1.3 Head Gap Adjustment (Black and Color head) The head gap printing alignment adjustment is required when the printer mechanism, the MAIN board, or the printhead (board) is replaced or disassembled. This adjustment adjusts the head drive timing between the black head and the color head. If this adjustment is not made, the vertical ali~ent will not be completed. 1. Connect the PC to the target printer and turn the printer on. 2.
PAGE 85
Stylus Color Service Manual Adjustments 4.1.4 Black Head Angle Adjustment The black head angle adjustment is required when the black head is replaced or disassembled. If this adjustment is not correct, the white banding problem might occur or the color head timing might not match the black head timing. The following figure illustrates the black head angle adjustment. The black head angle is adjusted by the linear spacer and the angular spacer.

Removing the Rubber Cap Afier replacing the spacw, always install new ink cartridges before returning the pn”nter to the user.
PAGE 88
Adjustments Stylus Color Semicp Manual 11. After replacing the angular spacer, reassembly the ink cartridge holder and reinstall the ink cartridges. Use the BASIC program to veri$ the black head angle. Confirm the angle condition by re-performing the step 1 to step6, and if the angle condition is wrong you must perform this adjustment until the head angle becomes correct. H The angular spacer comes in fi”ve thicknesses.
PAGE 89
Stylus Color Service Mhnual Adjustments 4.1.5 Black - Color Head Vertical Adjustment TMS adjustment adjusts the vertical position between the black head and the color head. (Join the top nozzle of both the #l nozzle of the black head ~d the #l nozzle of the color head.) This adjustment can be made only by using the linear spacer of the black head side. This adjustment is required when the black head or the color head is replaced or disassembled. The following figure illustrates this adjustment.
PAGE 90
Adjustments Stylus Color service Manual 4. In Figure 4-8, the vertical position is correct when both the magenta line and the black line are aligned [as in position OK (0)]. If the vertical position is correct, turn off the printer. If the black and magenta lines are not aligned, perform the vertical adjustment as described in steps 5-10. ■ The number shown in the sample indicates the thickness level compared with the current linear spacer (see step 5), and the linear spacer is prepared with 11 kinds.

Adjustments Stylus Color service Manual 4.1.6 Color Head Angle Adjustment The color head angle adjustment is required when the color head is replaced or disassembled. If this adjustment is not correct, the white banding problem occurs or the black head timing will not match the color head timing. The following figure illustrates the color head angle adjustment. The color head angle is adjusted by the angular spacer. The angular spacer is fixed to only left side of the base head.
PAGE 93
Stylus Color Service Manua/ Adjustment The angular spacer for the color head come in five thicknesses, each having its own shape. The following figure shows the relation of the shape and the thickness level. Since the color head is not equipped with a linear spacer, the angle adjustment is decided only by the angular spacer (exclusive use for color head), which is placed under the left side of the base head.
