The all-in-one machine is modified with a continuous ink supply system. When printing pictures continuously, ink reflow is prone to occur, which causes a lot of gas in the catheter to affect the printing effect. In the continuous supply of HP and CANON head box all-in-one machines, ink reflow has always been an annoying problem! Although some manufacturers have done some articles on the inner box, but after testing, it is still not satisfactory, the resistance is too great, and continuous high-speed printing cannot. Another example is some office printers, which may not be used for a long time, and the phenomenon of backflow sometimes occurs. Now, after installing a one-way valve (made of long-term corrosion-resistant material, positive resistance type) on the ink pipe, there is no need to worry about the problem of backflow. Moreover, the previously modified machine can also be reinstalled, the operation is simple, convenient and practical.
