Q: I have installed my Canon CISS and i have followed the instruction as it says, but still my printer doesn't print.

 This happens with all Canon and some HP printers (HP 564/920,.. type cartridges)

Why this happens? 

This happens if you keep the tank higher than your printer, forget to leave the small tank plugs open, forget to unlock the pipline holder, if the tanks are empty and you forget to refill the tanks before the air goes in the pipline or on delivery time the tanks move a lot.

What you need to do: 

Check the CISS' cartridges and see if they are full of ink.

If the non-sponge compartment (small compartment) of the cartridges are empty or contain less than 70% ink, you need to do the following:

How to Re-prime the Canon printer's Continuous Ink Supply System (CISS) cartridges

*Option 1:
**[Need sharp needles]

If you still have all of the cartridge's orange cover,

1- Close all the plugs on all the tanks

2- Close the pipeline holder

3- Please put the all the orange covers back

4- Leave the small tank plugs and unlock the pipeline holder

5- With a syringe and a needle remove air and some ink from the bottom of each

cartridge through the small silicon hole under the orange covers.

6- At the end of the procedure, use your printer software to do the head cleaning process once or twice and then prepare the air balance again.

This option is more helpful and practical, beacuse it's easy to remove the air from the non-sponge compartment , sponge and CISS lines.

*Please Note: You can do this option just once, because the sponge can be damaged by the needle

Option 2:

1- Close all the plugs on all the tanks

2- Close the pipeline holder

3-Disconnect ink line from the half empty cartridge by pulling the pipe connector out. 

4- Disconnect the ink line from the cartridge, by pulling it out.

Use a syringe with a needle and refill the cartridges as needed(95%). 

Do not overfill or the ink will leak out. 

5-Reconnect the ink line. Rinse the syringe with water for the other colours or use a new syringe

6- At the end of the procedure, use your printer software to do the head cleaning process once or twice and then prepare the air balance again

Option 3: (NOT for Big black)

(Preparing the air balance)

 Preparing the ROBUST V.4 tanks 

 Preparing the FLY V.3 tanks 

 Preparing the MBOX V.2 tanks 

How often this happens? 

Only for the first installation and not with all printers, or if you forget to refill the tank when it's empty.
