Chapter 1 Product Description 1.4 Control Panel Since EPSON Stylus Color 600 does not require many buttons since printer driver can start various settings and motions. Therefore, there are only 2 non-lock type push switches, 1 lock type push switch and 4 LEDs.
EPSON Stylus Color 600 1.4.2 Panel Functions Table 1-19. Panel Function Switch Function Load/Eject Loads or Eject the paper. (Pushing within 0.5 seconds*) When the carriage is on the Ink Cartridge change position, return the carriage from Ink Cartridge change position.
Initialization of I/F selection (returns to AUTO) WARNING EPSON Stylus Color 600 does not have “EEPROM All Clear” function like other printers. If the printer does not function well and falls into fatal error condition, replace the main board to see if the problem is rectified.
This thickened ink goes into the head and clogs ink path in the head or nozzle and may cause serious head damage. As standard specification for EPSON Stylus Color 600, ink consumption counter is reset when the ink cartridge is removed. If an ink cartridge is removed and re-installed unnecessarily the value on the ink consumption monitor which the user can check will be wrong and printer may keep printing even though the ink cartridge is installed empty.
Chapter 1 Product Description 1.5.4 No Ink-Cartridge Error Following reasons can be the causes when printer goes this error mode. When the printer is turned on for the first time. (This is a normal error state and it returns to the normal state after installing an ink cartridge according to the ink cartridge exchange operation.) Ink cartridge exchange operation is done correctly.

Also, if the user changes the settings in the Panel setting, Default setting or Remote command setting, values or settings which are possible to be stored are initialized as initialization settings.
Chapter 1 Product Description 1.7 Main Components EPSON Stylus Color 600 has following major units. Also, it is one of the major characteristics that the bottom of the Printer mechanism plays the role as lower case at the same time.
EPSON Stylus Color 600 1.7.2 C200 MAIN Board The C200 MAIN board controls whole mechanism operations and a data processing operation. Most of the functions of the circuit are integrated into single ASIC; E05B43YA (IC2) and this makes the board design very simple and reliable.
Chapter 1 Product Description 1.7.3 C206 PSB/PSE Board The C206 PSB/PSE board is a switching regulator type power supply unit and constantly supplies stable logic and power voltages to the printer mechanism and the main control board. Also, since this C206 PSB/PSE board has the power switch in the secondly side of the circuit, it is possible to keep supplying electricity to the C200 MAIN control board for 30 seconds even after the power switch is turned off.

Stylus Color 600. 2.1.1 Printer Mechanism Unlike previous EPSON Ink Jet printers, printer mechanism of Stylus Color 600 does not have exclusive mechanism to change over paper feeding and Pumping operation. In stead, this control is done by the turning direction of paper feed/pump motor and position of carriage at that time.
EPSON Stylus Color 600 As major printer mechanisms in the figure 2-1, there are four major mechanisms as they are listed below. 1) Printing mechanism 2) Carriage unit 3) Paper pick up mechanism 4) Pump drive mechanism 2.1.1.1 Printing Mechanism Basic principles of the print head which plays major role of printing mechanism is the same as previous models;...
Chapter2 Operating Principles 2.1.1.1.1 Printing Process Following figures indicate the sectional drawing of normal state and ejecting state of print head. (1) Normal State: When the print signal is not output, PTZ also does not move in the waiting state(normal state). Figure 2-3.
EPSON Stylus Color 600 2.1.1.1.2 Printing Method This section explains printing method of actual printing such as printing text at various resolution select/printing mode and graphics printing. In order to prevent white or color banding which are peculiar problem of ink-jet, new Micro-Weave functions are added to the previous Micro-Weave function. The number of nozzles and printing mode according to the selected resolution are used separately by a user.
Page 43
Chapter2 Operating Principles Note2) Two groups which are divided according to each elements will be divided either even dot or odd dot when particular lines(level direction line) are formed and eventually, these lines will be completed at selected resolution. Following is a conceptual figure when full overlap micro- weave orms a particular line.
Page 44
EPSON Stylus Color 600 The difference between Full-Overlap Micro-Weave and Part line Overlap Micro-Weave are following; Full-Overlap Micro-Weave: Printing is performed, judging if nozzles are even or odd dot by 2 different dots with all different rasters. Part line Overlap Micro-Weave: After particular nozzles(only#1, and #6 in the figure2-7) are determined as overlap nozzles, even or odd dot will be determined like Full-overlap Micro-Weave does.
Chapter2 Operating Principles 2.1.1.2 Carriage Mechanism Carriage mechanism is to drive the carriage with print head mounted from left to right or vice versa. The carriage drive motor in this printer is a 4-phase, 200-pole, stepping motor and is driven by 1-2phase, 2-2phase and W1-2phase drive method.
Page 46
EPSON Stylus Color 600 The table below shows W1-2 phase drive sequence at each steps when the rotor of carriage motor makes one rotation. In the Stylus Color 600, in addition to a function that printing is performed with W1-2 drive phase, high speed skip mode which is a function to skip over the blank from the end of the printing data to the next data starting point with high seed can be also performed by 2-2 and 1-2 phase drive.
Page 47
Chapter2 Operating Principles The figure below shows carriage mechanism. The print head as a core of the printing mechanism is stored in the carriage unit. This print head keeps the tilt of print head in flexible and adjustable structure by moving the adjustment lever up and down by the tilt adjustment mechanism.
EPSON Stylus Color 600 2.1.1.2.1 Paper Gap Adjust Mechanism This mechanism can be set by the users and can prevent various problems related to low image density or print with any dirt by changing the positions of PG lever according to the paper types.
Chapter2 Operating Principles 2.1.1.3 Paper Feed Mechanism and Pump Mechanism Mechanisms that send the paper in the hopper to inside the printer and perform constant paper feed in order to perform printing on the sent paper are called paper feed mechanism as generic name. In the Stylus Color 600, 4-phase, 200-pole hybrid type pulse motor is used in the PF motor as a motive power of the paper mechanism and driving is done at 2-2 and 1-2 phase drive method.
Page 50
EPSON Stylus Color 600 Papers on the ASF (auto-sheet-feeder) supplied by the user are carried to the printer inside by paper pick up sequence. Unlike the previous models, ASF of Stylus Color 600 has mufti feed prevention mechanism. Following explains this function and figure below shows its mechanism.
Page 51
Chapter2 Operating Principles In the paper pick up mechanism of Stylus Color 600, same mechanism as Stlylus Color IIs/820 are applied. This mechanism changes adjoined lines of gear by colliding trigger lever with carriage unit and convey the motive power on the platen to the ASF side(paper roller). The figure below shows mechanism with explanation.
EPSON Stylus Color 600 2.1.1.4 Ink System Ink system mechanism consists of 1)cap mechanism, 2)pump mechanism, 3)carriage lock mechanism, 4)waste ink absorber and 5)ink sequence. Out of these mechanism, from 1) to 4) are physical mechanism and parts which are mounted on the printer mechanism and 5) ink sequence is performed automatically by firmware.
Chapter2 Operating Principles 2.1.1.4.1 Pump Mechanism In the Stylus Color 600, there is no switch or mechanism to change over the pump/paper feed mechanism. Therefore, whenever the paper feed/pump motor rotate, pump drive roller in the pump unit inside rotates. However, ink absorption/non ink absorption are separated by the roller rotational direction. Also, even if the pump driver rotates toward ink absorption and the carriage position is in the false absorption position, only driving in the pump mechanism is performed and actual ink attraction is not done.
Page 54
EPSON Stylus Color 600 The table below shows PF/Pump motor rotational direction and pump system operation. Table 2-11. Relationship Between Pump Motor Rotation and Pump Operation PF/Pump motor rotational direction Pump unit operation Clockwise(CW) 1)Release from the Pump pressure welding...
Chapter2 Operating Principles 2.1.1.4.2 Cap Mechanism In the cap mechanism, in order to prevent ink from being thickened on the head surface, it is controlled that the head surface stays adherent to the rubber frame of the cap surface when the power is off. The absorber is spread in the cap and can hold a certain amount of ink which is absorbed from the head without draining it to the waste ink pad.
EPSON Stylus Color 600 2.2 Electrical Circuit Operating Principles Stylus Color 600 contains the following four electric circuit boards. C206 PSB/PSE board C200 Main board Head Driver board C206 PNL board C206 PSB/PSE, C200 board are explained in this section. The head drive board is installed in the head uniton the carriage.
Chapter2 Operating Principles 2.2.1 C206 PSB/PSE Board C206 PSB/PSE board is a power supply board with a RCC switching regulator, which generates +42VDC for drive part and +5VDC for logic part to drive the printer. One of the major characteristic of this board is that the same secondary switch is used as Stylus Color series printer.
Page 58
EPSON Stylus Color 600 Figure 2-18. C206 PSB/PSE Board Block Diagram The C206 PSB/PSE board has various control circuits to stop output if malfunction on the power supply board, on the main board or on the duty of printer mechanism happen. Following explains each control and protection circuits.
Chapter2 Operating Principles 2.2.2 C200 MAIN Board Various DC voltage generated on the C206 PSB/PSE board is added various signals in order to drive the printer function on the C200 MAIN board, and the drive of CR/PF(Pump) motor and printing head is performed.
Page 60
EPSON Stylus Color 600 Timer Data: The timer IC that uses lithium battery as power source monitors how long the power is off. When the power is turned on, it is changed to appropriate cleaning level according to the time that the power is off.
Chapter2 Operating Principles 2.2.2.1 Reset Circuits The reset circuit prevents the CPU from running away, which is caused by the unstable voltage in the logic line during the power ON/OFF. Also, this circuit monitors level of power voltage at the overloading or malfunction on the circuit and manages the printer to operate normally, keeping the damage to the printer minimum during the abnormal situations.
EPSON Stylus Color 600 2.2.2.2 Sensor Circuits The following sensor circuits are mounted in the Stylus Color 600 and selects appropriate operations based on the returned information. ASF Sensor: An ASF sensor detects the position of return lever when the power is...
Chapter2 Operating Principles 2.2.2.3 EEPROM Control Circuits The EEPROM of Stylus Color 600 has following contents. Gate array E05B43(IC2) controls operations of reading data when the power is on and writing data when the power is off. Ink consumption(Bk, CMY) CL counter(Various cleaning operations that are previously done are memorized) Destination information Information of various adjustment values(Bi-D, VH voltage, etc.)
EPSON Stylus Color 600 2.2.2.4 Timer Circuit The lithium battery is mounted on the C200 MAIN board and calculates how long the printer is not in used. The timer IC(IC10) starts counting with oscillation motivated by the CR3 using this battery as a power source.
Chapter2 Operating Principles 2.2.2.6 Print Head Control Circuit The print head control circuit of Stylus Color 600 has following characteristics. Common waveform circuit became one HIC. Micro-vibration mode is added.(when the CR motor is accelerating) High speed drive 14.4KHz (trapezoidal wave form Enhanced Nozzle configuration (resolution in the vertical direction)90dpi (However, black nozzle is 2 lines structure) Also, Stylus Color 600 has Micro-dot control as dot shooting control.
Page 66
EPSON Stylus Color 600 [Nozzle Selector Drive Circuit] In order to motivate the print head to carry out printing, it is necessary to transmit the print data to the appropriate nozzles, which becomes direct signals to drive PZT. This data transmission is performed by the serial transport method, however the data output for each black and CMY head is transmitted by the parallel method.
Page 67
Chapter2 Operating Principles After the data transmission by the nozzle selector(IR2C72C, IR2C73C) is completed and a certain time passes, trapezoidal wave form generated by the common drive circuit once sends electric current to the PZT for the proper nozzles which are determined in the nozzle selector circuit. This motivates PZT and ejects the ink in the cavity.
EPSON Stylus Color 600 2.2.2.7 PF(Pump) Motor Drive Circuit IC15(UDN2917) is used for driving PF(Pump) motor. In the IC, Bi-pola drive PWM current control type is performed, making it possible to provide stable current to each phase of motor. Also, it makes possible to change over the reference voltage as drive current settings by making 3 combinations(100%,66% and 33%), using 4 current setting ports(input).
Chapter2 Operating Principles 2.2.2.8 CR Motor Drive Circuit In the CR motor, the same UPD2917(IC14) as the PF motor has used. In the IC, Bi-pola drive PWM current control type is performed, making it possible to provide stable current to each phase of motor. Also, it makes possible to change over the reference voltage as drive current settings by making 3 combinations(100%, 66% and 33%), using 4 current setting ports(input).
