The scope of use of refillable ink cartridges mainly includes various inkjet printers, and is suitable for printers of various brands and models. For example, Lexmark 17 ink cartridges, Canon refillable ink cartridges, EPSON T series ink cartridges, etc. can all be refilled and used. Specifically:
Lexmark 17 ink cartridges: by punching a hole at the top of the ink cartridge and injecting ink, then sealing the ink injection port, and cleaning the residual ink before use.
Canon refillable ink cartridges: you need to peel off the sealing patch on the ink injection hole first, use a ball pusher to press the steel ball into the cartridge, and then slowly push the piston through the screw to inject ink into the cartridge.
EPSON T series ink cartridges: because the ink injection port is reserved during the design, you can directly inject ink into the cartridge through a needle.
