Page 44: Print Head Unit Movement
TM-U200D/U200PD Technical Manual Print head unit movement When the Motor, carriage is driven and the Gear, carriage motor is moved in the direction of arrow B (forward rotation), the rotational power is conveyed to the Pulley, belt drive, then the belt. Next the Carriage sub-ass’y, which is fixed to the belt, is moved in the direction of arrow B.
Page 45: Printing A Character (9X9 Font)
Printing a character (9x9 font) A character is printed by energizing the print solenoids with respect to the Carriage sub-ass’y portion (the reference timing for the print solenoids is the Motor, carriage phase switching signals). The print head unit is moved 0.317 mm (0.012”) (in approximately 1.05 ms) each time the Motor, carriage is rotated one step (7.5°).
