Use static tape on print heads. It has no adhesive and it needs to be applied properly. Many people do not know how to properly apply static print head sealing tape. The trick is to heat up print head before applying tape. Get yourself a hair dryer and heat up print head. Then take a strip of static tape and position it properly and while print head is warm simply dab your finger on tape over print head. The slight pressure will bond tape to print head and hold it in place. The heat temporarily expands tape so when it cools off it will shrink slightly and form a bond around print head. Add a cartridge clip and you have best known method for storing cartridges with print heads.

A note of caution here. Some of you will be tempted to use a heat gun. A Heat gun can throw off an amazing amount of heat, probably enough to destroy print head. If you don't have experience using a heat gun in this fashion please use a hair dryer.

Even if you don't refill a lot you might want to keep a roll of print head tape on hand. Sealing a color cartridge improperly can cause cross chamber migration of ink and that is a contamination that you definitely do not want to deal with.

Moving along with our analysis, next in terms of difficulty, or ease, depending on how you want to read this article, is Epson. Epson's are generally not that hard to refill but still there are tricks that will help you succeed. The biggest problem I see with Epson cartridges, aside from chips, is it's easy to inject air which causes micro bubbles which results in spotty printing. Advanced Epson refillers know to extract foamy air from an Epson cartridge before refilling it.

Last but not least is easiest cartridge in world to refill. Have you guessed yet? Repeat after me.... CANON BCI-3e and BCI-6. Canon does not use any technology on these cartridges which immediately gives them a leg up over Epson. These two cartridges are identical in physical form so from now on I will address them in singular. The only problem with refilling this cartridge (actually more accurately a ink tank) is that if you don't get a good airtight seal over refill hole it WILL leak. The best thing you can use is a hot glue gun. It seals hole very well and bubble of glue is easily removed with your fingernail when It's ready for next refill. We can't put a hot glue gun in a refill kit so next best thing is a 4 x 3/8 stainless steel screw if you use a 1/16" drill bit to make refill hole.
