Abstract
An inkjet printer gas pressure controller provided with a negative pressure test line, an inkjet printer including the gas pressure controller, and a method of testing negative pressure in the inkjet printer are proposed. The gas pressure controller having the negative pressure test line for controlling gas pressure includes a negative pressure generation unit capable of suctioning air and applying negative pressure through an output tube, a positive pressure generation unit capable of exhausting the air and applying positive pressure through the output tube, a negative pressure test line capable of testing the negative pressure generated by the negative pressure generation unit when connected to the negative pressure generation unit, and a pressure control module for controlling the negative pressure or positive pressure to be applied through the output tube by controlling a connection relationship between the negative pressure generation unit, the positive pressure generation unit, and the output tube.
