is wrong. It doesn't work for LC37 cartrdges, because they are not the same as LC51. There are no instructions on that site that work. Here's what I do:
You don't have to take the shell off the cartridge; it would be better if you did, but it doesn't come off nearly so easily as the above link says. It is glued together, so to take it off, you have to split the seam with a very sharp knife. If you can do this, the refilling job will be a lot easier as you will be able to see what you are doing. If you don't want to attempt it, you can still fill it "blind".
You need a 10ml syringe. You don't need a needle. The tip of the syringe is not quite long enough, so I had to make an extension for it. I used a piece of skinny tubing from the inside of an old spray bottle. I cut about 1" (2.5 cm) off and attached it to the end of the syringe using epoxy putty, like the stuff for patching leaking radiators. You can get it at any hardware. I put a piece of wire through it to keep it aligned while I was molding the putty around it.
After it sets, fill the syringe with 5ml of ink. Push it into the outlet hole of the cartridge while twisting it until it is firmly stuck into the hole. Turn the cartridge/syringe assembly so the syringe is up. Pull back on the handle and **** 5ml of air from the cartridge. Then gently squeeze the 5ml of ink in. Fill the syringe with another 5ml of ink and repeat. You may find it hard to **** air out without getting ink as well. The cartridge is built like a labyrinth inside, so there are lots of places for ink to get trapped. Twist and turn the cartridge and push and pull until you've got the 5ml of air. Then again put the syringe topmost and gently squeeze in the ink. If you have removed the shell, this will be easy to do. The main point is to make sure you remove the same amount of air as the ink you put in. Do not push the plunger valve. If you do, you very likely will get a handful of ink.
An LC37 only holds 10ml of ink, not 30 like the LC51.
When you are finished, you can gently push the plunger just slightly; if any ink comes out, you need to remove some more air. You can damage the printer if you install a cartridge that has pressure inside it. New cartridges have a vacuum inside; you can hear them go "whoosh" when you click them into place. If not a vacuum, you need to at least have neutral pressure before you install it. This is very important. The printer has sensitive electronic sensors mounted roght at the business end of the cartridges. If any ink gets spilled in there, your printer will likely be ruined. Be warned.
It is about impossible to do this without any spillage.
Wash the cartridge in running water, shake out the excess thoroughly and then dry it with a paper towel. Don't install it unless it is totally dry and not pressurized.
