    Mechanism 4-1. Print Head Mechanism 4-1-1. Character Mechanism The wiring arrangement of the guide section on the print head styles is depicted in Fig. 2-4. Odd- and even-numbered wires are arranged it two columns. This is a result of the necessity for laying adjacent dots on top of one another. Fig.

  • Page 31: Print Head Carrying Mechanism

    4-2. Print Head Carrying Mechanism The print head carrying mechanism consists of a carriage, timing belt, carriage motor, and home position detector. Carriage The carriage is supported horizontally by the carriage stay and rear angle. The carriage moves from side to side with the print head mounted above it.

  • Page 32: Ink Ribbon Feed Mechanism

    4-3. Ink ribbon feed mechanism The ink ribbon feed mechanism is linked to the print head carrying mechanism so the ink ribbon always winds automatically in the same direction while the carriage moves left and right. The movement of the carriage along the serrated edge of the rear angle of the printer mechanism drives the idler gear. The rotation of the idler gear is conveyed sequentially to the gears that work and wind the ribbon.

  • Page 33: Paper Feed Mechanism

    4-4. Paper Feed Mechanism The turn of the paper feed motor is transmitted to the PF (Paper Feed) roller and tractor unit via the release lever, front- rear release arm, tractor clutch lever, clutch gear and change lever. The paper feed motor is a HB (Hy Brid) 4-phase and 96 pulse motor.
