How do I refill lexmark 730 series ink cartridge?
Ehhh… I would be hesitant to refill an ink cartridge -ESPECIALLY a Lexmark brand. They have dozens of lawsuits against Lexmark because they make it pretty much impossible to refill them yourself. There are so many things that could go wrong and it’s just not worth it. Trust me, I had to learn the hard way. Pay someone else to do the hard work for you and get some compatible/remanufactured cartridges. I’ve been getting mine from toneramerica.com for 10+ years and I’ve never had a problem with them.
