Chapter 2 Operating Principles 2.1 OVERVIEW ...............................................................................................................1 2.1.1 Printer Mechanism .................................................................................................................... 1 2.1.1.1 Printing Mechanism ...................................................................................................... 2 2.1.1.1.1 Printing Process .....................................................
Chapter2 Operating Principles 2.1 OVERVIEW This section describes Printer Mechanism, electric circuit board (C206 PSB/PSE, C206 Main, C206PNL board) of Stylus Color 400. 2.1.1 Printer Mechanism Unlike previous EPSON Ink Jet printers, printer mechanism of Stylus Color 400 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 400 Service Manual 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; on demand type MACH head method, but there is some difference in the resolution.
Chapter2 Operating Principles 2.1.1.1.1 Printing Process Following figures indicate the sectional drawing of normal state and ejecting state of the print head. (1) Normal State: When the print signal is not output, PTZ also does not move in the waiting state(normal state). Ink Course PZT Nozzle Cavity Nozzle Plate Figure 2-3.
EPSON Stylus Color 400 Service Manual 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.
Note2) Chapter2 Operating Principles 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 microweave orms a particular line. Condition: 360-dpi printing Nozzle: Total 10 nozzle/each color Nozzle No.#9 Nozzle No.#4 Particular line(Completed line) 360-dpi Figure 2-5.
EPSON Stylus Color 400 Service Manual 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.
EPSON Stylus Color 400 Service Manual 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 400, 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.
Chapter2 Operating Principles The figure below shows the 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.

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 400, 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.
EPSON Stylus Color 400 Service Manual 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 400 has mufti feed prevention mechanism. Following explains this function and figure below shows its mechanism. [1. Multi feed prevention mechanism] When the Load/Eject button is pressed, reversed rotation of PF motor is performed.
Chapter2 Operating Principles In the paper pick up mechanism of Stylus Color 400, same mechanism as Stylus 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. [2.
EPSON Stylus Color 400 Service Manual 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 400, 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.
EPSON Stylus Color 400 Service Manual The table below shows PF/Pump motor rotational direction and pump system operation. Table 2-11.
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 400 Service Manual 2.2 Electrical Circuit Operating Principles Stylus Color 400 contains the following four electric circuit boards.

Chapter2 Operating Principles 2.2.2.6 Print Head Control Circuit The print head control circuit of Stylus Color 400 has following characteristics. Common wave form circuit became one HIC. Slight vibration mode is added.(when the CR motor is accelerating) High speed drive 14.
EPSON Stylus Color 400 Service Manual [Nozzle Selector Drive Circuit] In order to motivate the print head to carry out printing, it is necessary to transmit the printing data to the appropriate nozzles, which becomes direct signals to drive PZT. This data transmission is performed by the serial method, however the data output for each black and CMY head is transmitted by the parallel method. The figure below shows data transmission circuit.
Chapter2 Operating Principles After the data transmission by the nozzle selector(IR2C72C) 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. The figure below shows normal dot data transmission timing in order to form 1 dot. Figure 2-26. Timing Chart at the Generation of Normal Dot Rev.

EPSON Stylus Color 400 Service Manual 4.2.2 Adjustment by Adjustment Program In this printer, it is necessary to set correct information for each printer mechanism in order to maintain homogeneous printing function and quality, erasing dispersion of each printer mechanism’s characteristics.
Chapter4 Adjustment 4.2.2.2 Initial Ink Charge Operation There is no ink charged in the ink path of the print head that is mounted on the print head and printer mechanism as spare parts. Therefore, when the following units are exchanged, perform initial ink charge and return the printers after making sure that ink is discharged correctly from the print head. When exchanging the printer mechanism When exchanging the print head When exchanging the C206 main board (Refer to “Caution” below.
EPSON Stylus Color 400 Service Manual 4.2.2.3 VH Voltage Writing Operation There are dispersion in the PZT which are used for print head. It is necessary to set available and appropriate printing by registering mean values(VH voltage) of these PZT dispersion in the EEPROM. Therefore, when the next operations are done, it is necessary to confirm VH voltage ID and to register to EEPROM on the main board by the program.
Chapter4 Adjustment 4.2.2.4 Print Head Angle Adjustment The dispersion of print head and carriage that is the base of installing the print head are caused during the production and gives bad influences on the angle of the print head. If the angle of the print head is not correct, overlap of colors is not performed correctly. This results in causing color lines or white lines. In order to prevent this, an exclusive lever to adjust the print head angle is installed in the side face of the carriage unit.
EPSON Stylus Color 400 Service Manual 9. Loosen a screw securing the print head on the carriage. (It is not necessary to remove it completely: Refer to the figure below.) Print Head Screw Figure 4-5. Position of the Print Head CAUTION Make sure to loosen the screw. If the screw is not loose, the print head angle can not be changed even if the position of the adjust lever is moved. 10.
Chapter4 Adjustment 4.2.2.5 Bi-D Adjustment This adjustment is to correct dispersion of printing positions caused by slippage of printing timing in right and left direction during the bi-directional printing. Therefore, it is required to perform this adjustment if the following operations are performed.
