A wide-format color printer includes a carriage, an ink carrier (2) disposed on the carriage, a motor (3) for driving the carriage and a guide-rail frame (4). The motor is mounted on the carriage and a motor wheel (3-1) of the motor is fitted to a guide rail (4-1) of the guide-rail frame. An anti-friction strip (6) is disposed on the bottom of the guide rail. The carriage includes a carriage frame (1-1) and a motor holder (1-2). The ink carrier is buckled to a front end face of the carriage frame. The motor is fixed to the motor holder. The motor holder is connected to the carriage frame through an elastic member (5) on the top of the motor holder. The motor of the printer drives directly the carriage frame to move on the guide rail of the guide-rail frame reciprocally. A transmission without a belt or a wire rope is achieved and a stable sliding of the ink carrier during the transmission is ensured, so fitting problems previously caused by belt transmission or wire rope transmission are solved, and thus printing accuracy, printing speed and printing stability are improved. |
