PURPOSE:To provide a low-cost, compact ink jet device capable pf ensuring high-quality recording and high reliability by driving a device to transport a recorded material and an ink discharge state recovery device using a common drive source, and at the same time, causing the initial action of said devices to take place using a single sensor when a power supply for the device is turned ON. CONSTITUTION:A sheet transport guide part 23 consists of each sheet feed roller 23a, 23b, and guides a sheet 3 which is fed from a cassette 22 using a pickup roller 21, to a subscan roller 7. A printing part 8 prints the sheet by causing liquid droplets to be ejected by a printing head 9 which is movable in a sheet width direction due to each guide rail 9a, 9b. In the meantime, a cap is caused to come in contact with an ink jet head using a non-printing device, and at the same time, a tube is squashed using a guide roller through a pressure roller to perform a suction recovery action. In this case, the pickup roller 21 and the guide roller are driven by a common drive source. If a power supply for the device is turned ON, the initial action of the mentioned each roller is started by a single sensor. |
