Continuous ink supply systems, or CISS, are third-party ink attachments for inkjet printers. Inkjet printers normally include small ink cartridges, each of which is fairly expensive to replace. A continuous ink supply system has a much larger amount of ink, with tubes that feed directly to special cartridges which are inserted into the printer. Priming is a process which removes excess air from the CIS system's tubes. Only prime the CISS if a large amount of excess air, about two inches or more, is present in the CIS system's tubing.

  1. 1

    Put on a pair of gloves to protect your hands from any leaking ink.

  2. 2

    Remove the CIS system from the box it came in or unplug it from the printer. Place it on a clear, flat area with its ink cartridges upside down.

  3. 3

    Remove the cover from the ink cartridge connected to the tube with the excess air by turning it counterclockwise.

  4. 4

    Cover the hole where the cover was on the ink cartridge with tissues. Ink and air bubbles will come out of here as part of the priming process.

  5. 5

    Release the clamp on the ink tubes where they connect to the CISS by rolling the roller up.

  6. 6

    Remove the plug from the top of the ink chamber for the tube you want to prime. For example, if you want to prime the black ink tube and cartridge, release the plug from the top of the black ink chamber.

  7. 7

    Fill the syringe, often included with the CIS system, with air by pulling its plunger back.

  8. 8

    Place the tip of the syringe in the hole where the plug was at the top of the ink chamber.

  9. 9

    Push the syringe's plunger down very slowly. The air slowly forces the ink down the tube, forcing the air out of the sponge at the end of the ink cartridge.

  10. 10

    Pull the syringe back about 0.4 inches when the ink cartridge appears to have very little air in it. This relieves the pressure in the chamber.

  11. 11

    Remove the syringe from the hole on top of the ink chamber carefully, then insert the plug back in the hole.

  12. 12

    Repeat this process for each chamber that requires it.
