In the case that the suction cap performs suction from a black head, when the carriage moves toward the cleaning mechanism side, the first contact portion and the third contact portion come into contact with each other to position the carriage and the slider in such a manner that the suction cap faces the black head. On the other hand, in the case that the suction cap performs suction from a color head, when the carriage moves toward the cleaning mechanism side, the second contact portion and the fourth contact portion come into contact with each other to position the carriage and the slider in such a manner that the suction cap faces the color head. | 12-17-2009 |
20090309919 | INKJET RECORDING APPARATUS AND METHOD OF CONTROLLING THE SAME - An inkjet recording apparatus includes an encoder, a storage section, a difference calculating section, a threshold value determining section, a correction amount calculating section, and a controlling section. The storage section stores a capping target position and threshold value. The difference calculating section calculates a difference between a stopping position where a carriage is stopped for capping the recording head and a carriage position after passage of a predetermined time from when the carriage is stopped at the stopping position. The stopping position and carriage position are detected by the encoder. The threshold value determining section compares the threshold value and difference with each other. When the difference is greater than the threshold value, the correction amount calculating section calculates a correction amount of the capping target position. The controlling section moves the carriage to the capping target position corrected on the basis of the correction amount. | 12-17-2009 |
