A printer clean system includes a base, an ink stack assembly, a scraper assembly, a power transmission device and a driving device. The ink stack assembly is disposed on a first accommodation groove. The scraper assembly is disposed on a second accommodation groove. The power transmission device is connected with the driving device, the ink stack assembly, and the scraper assembly. When the power transmission device is rotated to a first angle, the ink stack assembly is brought to an ink stack clean position. When the power transmission device is rotated to a second angle, the scraper assembly is brought to a scraper clean position. When the power transmission device is rotated to a third angle, the ink stack assembly is located at an ink stack return position, and the scraper assembly is located at a scraper return position. Therefore, the pollution can be avoided.
