  • Page 40: Printing Process

    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 printing order is not output, PTZ also does not move and stays in the waiting mode (normal state).

  • Page 41: Printing Method

    EPSON Stylus Photo 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 42 Chapter2 Operating Principles Note 2) The way firmware decides which nozzle becomes even dot or odd dot is determined as it is described below. If the line which is about to be printed is even line: First dot prints odd dot lines and 2nd dot prints even dot lines. If the line which is about to be printed is odd line: 1st dot prints even dot lines and 2nd dot prints odd dot lines.
  • Page 43 Micro-Weave, and ordinal Micro-weave according to the selection of resolution. Also, when these three printing modes are performed by the EPSON Stylus Photo, the printer performs top and bottom margin process in order to control the overprinting volume as little as possible.

  • Page 44: Carriage Mechanism

    Chapter2 Operating Principles 2.1.1.2 Carriage Mechanism Carriage mechanism is to drive the carriage with print head 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 45 The table below shows W1-2 phase drive sequence at each steps when the rotor of carriage motor makes one rotation. In the EPSON Stylus Photo, 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 in high speed, can be also performed by 2-2 and 1-2 phase drive.
  • Page 46 Chapter2 Operating Principles The figure below shows carriage mechanism. The print head as a core of the printing mechanism is installed in the carriage unit. This print head keeps the angle of print head in flexible and adjustable structure by moving the adjustment lever up and down with the Angular adjustment mechanism. (Refer to chapter 4 for more details) Also, parallelism adjustment lever is mounted on right side of the carriage guide shaft and it adjusts parallelism between paper and shaft when this shaft is installed to the printer mechanism.

  • Page 47: Paper Gap Adjust Mechanism

    EPSON Stylus Photo 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.

  • Page 48: Paper Feed Mechanism And Pump Mechanism

    In the EPSON Stylus Photo, 4-phase, 200-pole hybrid type pulse motor is used in the PF motor as a motive power for the paper mechanism and driving is done at 2-2 and 1-2 phase drive method.
  • Page 49 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 EPSON Stylus Photo has multi feed prevention mechanism. Following explains this function and figure below shows its mechanism.
  • Page 50 Chapter2 Operating Principles In the paper pick up mechanism of EPSON Stylus Photo, 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 paper feed assembly to the ASF side(paper roller). The figure below shows mechanism with explanation.

  • Page 51: Ink System

    5) ink sequence is performed automatically by the firmware. Also, unlike the previous models, since EPSON Stylus Photo has no engage/disengage mechanism to change over pump mechanism and paper feed mechanism, it is one of the major characteristics that pump and paper feed assembly are always at work whenever the PF motor is driven.

  • Page 52: Pump, Carriage Lock, Head Cleaner Mechanism

    Chapter2 Operating Principles 2.1.1.4.1 Pump, Carriage Lock, Head Cleaner Mechanism In the EPSON Stylus Photo, there is no button or mechanism to change over the pump/paper feed mechanism. Therefore, whenever the paper feed/pump motor rotate, the pump drive roller in the pump unit inside rotates.
