ABSTRACT:
A kit and method for flushing an ink delivery system of an inkjet printing device so that different printing composition may be used in the printing device are disclosed. An embodiment of the kit includes a fluid module, a coupler, and a vacuum source. The fluid module stores a quantity of fluid for flushing the ink delivery system. The coupler is fluidly connectable to the fluid module and configured to be fluidly and removeably coupled to a first end of the ink delivery system. The vacuum source is configured to be fluidly and removeably coupled to a second end of the ink delivery system, and further configured to be manually actuable to create a vacuum that draws the fluid from the fluid module into the ink delivery system thereby flushing the ink delivery system. An embodiment of the method includes the steps of fluidly and removeably coupling a fluid module to a first end of the ink delivery system of the printing device and fluidly and removeably coupling a vacuum source to a second end of the ink delivery system of the printing device. The method additionally includes the step of manually drawing a vacuum at the second end of the ink delivery system of the printing device thereby drawing fluid out of the fluid module and into the first end of the ink delivery system, and further thereby drawing ink and the fluid out of the second end of the ink delivery system.
