Easy-to-add ink box is a modified super-capacity ink box, which is to remove the cover of the original ink box, take out the built-in sponge, cut the built-in small grid with professional tools to expand the volume of the ink storage bin, and seal the top cover of the air pressure balancing device specially designed by the national technical patent to keep the vacuum in the box and ensure no ink leakage. At the same time, the chip that controls the printing amount of the original ink cartridge is shielded by professional technology (when the original ink cartridge prints to a certain amount, the printer counting chip is locked and cannot be printed, even if there is ink, it cannot be printed at this time.
Easy-to-add ink box is exactly the same as the original ink box in appearance, except that the internal structure is adjusted, the sponge used to control the ink flow in the original ink box is removed, and the internal space is opened to increase the capacity of the ink box, and then a special top cover with an air pressure balancer is equipped to seal and inject special ink. The modified ink cartridge does not leak ink, block or dry up, and can be reused.
