  • Page 9: Press Contact And Release Mechanism Of Thermal Head

    2.1.2 Press Contact and Release Mechanism of Thermal Head The head ASSY is pressed firmly against the platen by the force of spring. When the release levers L and R are pulled upwards, they are unlocked so that the platen and top cover are released.

  • Page 10: Tape Feed Mechanism

    2.1.3 Tape Feed Mechanism When the tape is fed, the tape is pressed against the thermal head, which is nipped between the platen and the thermal head. Here, the tape feed motor (step motor) rotates, of which drive power is transmitted via the gear train to the platen gear and the platen, and consequently the platen can feed the tape.

    2.3.2 Key, LED Circuit - Power supply ON/OFF circuit This circuit detects the state of ON/OFF of the POWER button. Pressing this button in the power supply OFF state (LED OFF), LOW signal is sent to the CPU. Then the CPU starts initializing process and establishes the status of power supply ON (LED ON and ready for date acceptance from PC).

    2.3.3 Head and Motor Power Supply ON/OFF Circuit Turning the CPU status of 91pin (VHON) to High, Q2 turns ON, V (25V power supply) turns ON and consequently the head and motor is energized. Turning the CPU status of 91pin (VHON) to Low, Q2 turns OFF, V (25V power supply) turns OFF and consequently the head and motor power supply is cut off.

    2.3.4 Full Cutter Motor Driver Circuit and Media Feed Motor Driver Circuit (1) Full cutter motor driver circuit The circuit drives the DC motor to cut a medium as described in subsection 2.1.4 "Automatic Tape Full Cutter Mechanism". When the CPU receives cut request from the key or software, it confirms that the top cover ASSY is closed, and turns VHON (91 pin) High.

  • Page 22: Media Position Detect Sensor Circuit And Cover Open Sensor Circuit

    Figure 2.3-6 Media Position Detect Sensor Circuit (2) Cover open sensor circuit TD-4000/4100N has the cover open sensor. It identifies open/close of the top cover ASSY from the status of mechanical switch. Opening the top cover ASSY, the contact of cover open sensor on SB PCB opens.

  • Page 23: Head Temperature Detect Circuit

    The change of status is sent as the signal through CN14 to CUTSEN (74 pin) of the CPU. TD-4000/4100N first confirms that the cutter stays on its' home position prior to printing. When the cutter returns to the home position, the cutter home position sensor circuit recognizes it and stops the DC motor rotation.
