  • Page 47: Carriage (cr) Mechanism

    Operating Principles 2.2.3 Carriage (CR) Mechanism The CR mechanism is composed of the CR unit, timing belt, CR guide shaft, paper eject frame, HP sensor (Home Position sensor) and CR motor. The CR motor sends torque to the timing belt to move the CR unit in the both right and left directions along the paper eject frame and CR guide shaft.

  • Page 48: Paper Feed Mechanism

    EPSON Stylus &2/25 1520 2.2.4 Paper Feed Mechanism The paper feed mechanism of this printer consists of the integrated ASF (Auto Sheet Feeder) mechanism, tractor mechanism, PF (Paper Feed) motor, front/rear PE (Paper End) sensors, PF roller, paper guide mechanism, paper eject unit, and PF motor drive disengage mechanism. The torque from the PF motor drives the paper load mechanism, paper feed mechanism and paper eject mechanism.

  • Page 49: Asf (auto Sheet Feeder) Mechanism

    Operating Principles 2.2.4.1 ASF (Auto Sheet Feeder) Mechanism Torque from the PF roller is transmitted to the pick up roller in the ASF mechanism via the planetary gear by the PF motor drive disengage mechanism which switches the torque based on the detected position of the CR unit.

  • Page 50: Tractor Mechanism, Manual Feed Mechanism

    EPSON Stylus &2/25 1520 2.2.4.2 Tractor Mechanism Torque sent from the PF motor to the gears at the left end of the PF roller is transmitted to the tractor gears via disengage mechanism by the release lever operation. When the release lever is set to the tractor side, the release sensor detects the position and the torque from the ASF mechanism is disengaged consequently.

  • Page 51: Platen Gap (pg) Adjust Mechanism

    Operating Principles 2.2.5 Platen Gap (PG) Adjust Mechanism The PG adjust mechanism, located at the top right of the printer mechanism, allows the user to set the proper platen gap (distance between paper and nozzle surface) for the paper thickness to prevent ink smudging.

  • Page 52: Ink System

    EPSON Stylus &2/25 1520 2.2.6 Ink System The ink system for this printer is composed of the following mechanisms. „Ink cartridge „Pump mechanism „Capping mechanism „Waste ink drain pads „Wiping mechanism Figure 2-9 shows the block chart of the ink system.

  • Page 53: Pump Mechanism

    Operating Principles 2.2.6.1 Pump Mechanism 1. Switching operation from the paper feed mechanism to the pump mechanism The PF motor also functions as the pump motor by the switching operation of the PF motor drive disengage mechanism. When the CR unit returns to the home position, the switch lever in the CR unit pushes the cam lever.

  • Page 54

    EPSON Stylus &2/25 1520 2. Switching operation from the pump mechanism to the paper feeding mechanism When the CR unit shifts from the right end to the left end, the switch lever in the CR unit pushes the cam release. Then the disengage gear switches the torque from the pump mechanism to the paper feed mechanism as a result.

  • Page 55

    Operating Principles 3. Pump Mechanism Operation The pump mechanism absorbs ink inside the printhead and drains the ink to the waste ink drain pads via the cap. Since this printer has black and color heads, the pump mechanism functions for the both heads by alternating rotational directions of the PF motor.

  • Page 56: Capping Mechanism

    EPSON Stylus &2/25 1520 2.2.7 Capping Mechanism The capping mechanism caps the printheads with the cap holders to prevent the ink around the nozzles from increasing viscosity while the printer is in the stand-by status or the printer power is off. The cap is individually equipped for the black and color head.

  • Page 57: Wiping/cr Lock Mechanism

    Operating Principles 2.2.7.1 Wiping/CR Lock Mechanism The wiping mechanism removes the ink and dust adhered around the nozzles. This is operated during a cleaning sequence. When the PF motor rotates backward, the torque sent via the head cleaner (wiper) drive gear and the clutch moves the head cleaner to the path of the printhead. Then the CR unit moves right and left to wipe the nozzle surface against the head cleaner.
