    CHAPTER 2. BASIC OPERATION II. CARRIAGE UNIT A. Outline Figure 2-201 shows the composition of the carriage and its driving components. The driving force from the carriage motor (M2) is transmitted to the carriage through the carriage belt , causing the carriage to move back and forth over the paper. The distance it moves is controlled by counting the number of pulses of the signal transmitted from the engine control- ler to the carriage motor.

Home position sensor (PS2) * Detects the home position. Remaining ink sensor (PS3) * Detects the ink level remaining in the ink tank. Ink tank sensor (PS4) * Detects presence of ink tank.

  • Page 81: Operation

    CHAPTER 2. BASIC OPERATION B. Carriage Motor Control 1. Outline The carriage motor (M2) of this machine is a 2-phase stepping motor. It controls the back and forth movement of the carriage. The carriage motor (M2) is controlled by the engine controller, the main functions of which are shown below.

  • Page 82: Detection Of Front Cover Open/Closed

    CHAPTER 2. BASIC OPERATION b. Direction control The output timing of the motor drive pulses (YMA, YMAN, YMB, YMBN) from the carriage motor driver is changed by the carriage motor driver control signals (MTP12-15) output from the CPU, to control the direction of the carriage motor (M2). c.

    CHAPTER 2. BASIC OPERATION C. Linear Encoder 1. Outline A linear encoder is installed on the printer to allow checking the carriage operation and ad- justing the dot placement position on the paper. When the carriage is returning, after the home position sensor (PS2) turns ON and the carriage has travelled an additional 12mm, that position is considered the home position.

  • Page 85: Media Sensor

    CHAPTER 2. BASIC OPERATION D. Media Sensor 1. Outline The printer is provided with a media sensor to detect the width and skew of the paper, the internal temperature, and to enable automatic head adjustment. The media sensor is located on the carriage unit and composed of a red and a blue LED and one reflective photo sensor.

  • Page 86: Skew Detection

    CHAPTER 2. BASIC OPERATION 3. Skew detection By comparing the detected right edge position of the paper after a certain volume of paper has been fed, with the position of the right edge detected during the paper width detection operation, paper skew can be detected.
  • Page 87 CHAPTER 2. BASIC OPERATION If the skew value is more than the specified amount, the paper is determined to be skewed. The skew value here is the divergence between the paper's right edge at the time of paper width detection and the right edge at the time of skew detection. When paper skew is detected, the printer returns the carriage to the home position and stops operation.

  • Page 88: Light Compensation

    CHAPTER 2. BASIC OPERATION 4. Light compensation The media sensor brightness is automatically compensated for at the time of paper width detection and automatic print position adjustment. The carriage is advanced for approx. 200mm, the light quantity on the paper is compensated for in the order of blue and red, and then the light quantity on the platen is compensated for in the order of blue and red.

  • Page 89: Automatic Print Position Adjustment

    CHAPTER 2. BASIC OPERATION 6. Automatic print position adjustment When cartridges are installed on the carriage, the nozzle positions of the cartridges may be displaced, causing displacement of dots of different colors on the paper. The automatic print position adjustment compensates for this displacement. The head is automatically adjusted vertically (paper feeding) and horizontally (carriage move- ment) as follows.
