Add 3-4ml of ink with 5% coverage, and the maximum number of pages is 100. The inside of the ink box is a sponge for ink adsorption to avoid ink leakage caused by external conditions such as vibration. You can use the ink injector when refilling ink, which is simple and convenient. There is a sponge in the original ink cartridge. The principle is not so complicated. Just pay attention to the nozzle and chip of the printer. Insert or lock it! At present, it is more popular to convert ink cartridges into easy-to-add ink cartridges. After modification, the sponge inside the ink cartridge was removed and replaced with an ink cartridge cover with a balanced air pressure device to ensure no ink leakage. The key is not to add 1-2 times as much ink as the original ink cartridge. Lock the chip, and the easy-to-add ink (continuous adding ink) cartridge can be printed at least 5-6 times 100.
I hope I can help you with my hands.
