Refill Instructions Canon CLI-36

Theory

The ink in these cartridges are retained because the cartridges have an internal sponge.

Instructions

Step 1) Put the cartridges on some paper towels in an area where you can tolerate a spill.

Step 2) Turn the cartridge up side down so that the outlet ports of the cartridge are facing upward.

Step 3) Fill the syringe with 4cc of the appropriate color ink. 

Step 4) Drip ink onto the felt pad in the outlet port. The felt pad will quickly absorb the ink into the cartridge. If the felt pad will not soak up any more ink and the ink just sits on top then that chamber is full. Dab a paper towel onto the felt pad to soak up any ink that did not get absorbed into the cartridge.
It goes without saying that you want to put the correct color into the correct chamber. Don't drip yellow ink onto the cyan felt pad and wonder why you are now getting green.
Note: Do not pierce the felt pad with the needle of the syringe.

Step 5) Replace the cartridge and run 1 - 2 cleaning cycles as per printer instructions.

If necessary leave cartridge in printer for up to 4 hours to allow the ink to saturate the entire sponge.
Note: Immediately refill any empty cartridges.
