Inkjet printers are provided. An inkjet printer includes an ink tank, an inkjet unit, a first slider, and a cam mechanism. The inkjet unit includes a reservoir, and the reservoir has a first valve with the first slider movably connected thereto. Ink is transferred from the ink tank to the reservoir when the first valve is open. The cam mechanism includes a shaft and a first cam fixed thereto. When the cam mechanism rotates to a first position, the first cam impels the first slider in a first direction and opens the first valve.
