Theory
The ink in these cartridges is retained because the cartridge has an internal sponge.
Special Caution
The clear WJ811 fluid (print enhancer fluid) is particularly tricky to work with. If
this fluid contacts the ink, the ink will instantly dry and be nearly impossible to
remove.
Canon uses this fluid to create a quick-dry effect when printing on non-coated plain
paper. Unfortunately, if a drop of this fluid gets on a printhead which contains ink (or
vice versa), the material instantly forms a substance similar to acrylic in texture.
Use extreme caution handling this fluid near your printer and in handling inks
near this fluid. Otherwise, you will find yourself with a clogged printhead!
A few other comments
- Our chemist ran tests using the original Canon cartridges with the original ink. He ran
tests with over a dozen cartridges. In all cases, running full pages of black print, there
were present white lines, streaks, and density variations when the print enhancing fluid
was used. During this test, the black ink cartridge averaged 45 pages while the enhancing
fluid lasted 105 pages on average. - The black chamber and the clear chamber both have air detecting tubes which are used to
sense when the chamber is empty. When refilling, occasionally there will be air bubbles
remaining in these tubes after refilling, so there will seem to be enough ink, but the
printer will beep that you are out of ink.We recommend never running these cartridges
dry. Your refilling will be much better if you refill whenever you get to about a quarter
of the cartridge remaining.
- If the clear chamber goes dry, it is almost impossible to refill successfully. Luckily,
the clear chamber typically outlasts the black chamber by a ratio of 2:1, so we recommend
topping off the clear chamber with 5-7 cc of ink every time you refill
the black chamber. - We ran a half dozen of the original Canon black cartridges out of ink and 4 of them
experienced some permanent blockage of some of the print nozzles before running out of
ink. This was during very heavy full page printing. We believe that this is due to
overspray of the clear print enhancing fluid.We suggest that you not use the print
enhancing fluid where possible. It is designed for use on plain paper -- as opposed to
coated inkjet paper.
- The clear fluid will react with most metals -- except stainless steel. It also reacts
with many plastics. We suggest that you only use syringes which are made of stainless
steel, polyethylene, or polypropylene. Our syringes are made of these materials. If you
use another material, the fluid will form a cloudy mess that will eventually clog the
printhead. - Now that we've frightened you, let us add that this material is similar to Calgon water
softener. In other words, it is non-toxic but may cause eye irritation. Wash with plenty
of water.It's not that bad to people, but this fluid is a pain to work with around
ink. Canon put it in -- we provide it as a service.
Instructions
1. Seal the outlet hole(s) in the base of the cartridge
with tape.
2. Peel back label on top of cartridge enough to expose
the filling holes, as shown. It will be the same on the black cartridge.
3. Enlarge the filling hole(s) in the top of the
cartridge(s) using a 1/16" hand drill.
4. Push needle all the way into the cartridge of the
appropriate color filling hole. Note: The cartridge contains sponge and a slight
resistance may be felt. Very slowly inject up to 10cc of black ink or 5 cc of color
ink into the sponge until the cartridge is full.
Remember the black cartridge also has a clear liquid that is filled on the opposite side
from the black.(Now, always top off the clear fluid with about
5-7 cc of WJ811 fluid. It is vital that this chamber not be allowed to go dry. Reread the
Special Caution above. Be sure not to get any clear fluid on the black exit hole.) When full, ink may seep from the filling and outlet holes.
5. Seal the filling holes(s) in the top of the cartridge
by reapplying the label.
6. Unused ink may be returned to the bottle. Clean the
syringe with water and dry for future use, or use with a different color ink.
7. Remove the adhesive tape on the outlet hole(s) and run 1 - 3 cleaning
cycles as per printer instructions.
BC-62 Photo Cartridge
The BC-62 photo cartridge has 6 ink wells. The ink wells on the
front of the cartridge are the normal inks. The 3 ink wells on the back of the
cartridge are the photo inks. Each ink well will hold up to 3cc of color ink.
Fill according to the instructions above.
