Canon BC-20/23 (Also includes: Canon BJC-4000, BJC-4100, BJC-4200, BJC-4550, BJC-5000)

Refilling the BC-20/23 Cartridge

1. For the Black BC-20 or BC-23 Cartridge, locate the round circle on top
   of the cartridge. There is a small hole off-center inside this round circle.


2. Use a 1/16 inch Thumb drill provided enlarge this small hole on top of the cartridge.
   (This may be covered by a label.) Drill completely through the plastic into the sponge.


3. Inject the Black BC-20/23 cartridge with about 30 cc of ink -- a full syringe. Insert
   the needle all the way into the cartridge deep into the hard sponge.


4. Inject S-L-O-W-L-Y to fill the entire cartridge. Be sure to remove and re-insert the
   needle a few times to expose the entire sponge to the ink.


5. You only need cover the hole with a piece of aluminum tape for extended storage or
   transportation to prevent leaking or drying out. Remove the tape when printing.



6. Set on a paper towel for an hour as a drip precaution. Expect a few drips. Cover all
   holes during storage to prevent leaks and evaporation.


7. Replace the cartridge and run 1 - 3 cleaning cycles as per printer
   instructions.
