Part 5: REFERENCE BJC-6500 1.4 Transmission Gear Unit Depending on the carriage position, the transmission gear unit switches the paper feed motor's drive power over to drive the purge unit or the auto-sheet feeder. The slide arm that moves with the carriage action controls the timing of the switching and the operation. Part A Slide Arm Figure 5-5 Drive Switching Unit ASF drive occurs when the slide arm depresses part A. When this occurs, the internal rocker arm applies pressure to engage the ASF drive gears. With the gears engaged, the ASF drive gears rotate, and ASF driving takes place. The ASF gear is controlled by a single rotation clutch, as in the BJC-6100, and after rotating one turn, rotation stops. With the single rotation clutch, when the carriage depresses part A once, the pick up roller can be rotated, allowing paper feeding to occur during printing. As a result, matching the phase of the ASF drive gear is necessary. For details, refer to Part 2: 2.4.5 How to adjust the ASF gear position (Page 2-14). Purge driving occurs when the slide arm flag secures the switching flag in the purge drive position.
