When you receive your pre-filled Piano Book CISS, you may think the ink tanks are not pre-filled with 100 ml of ink for each color. This is because this patent design has two chambers: front and rear ones.
The rear one holds the majority of the ink; and the front one shows only small amount of the ink. When you lean your ink tank forward at about 30 degree with the black caps on, you will find more ink coming to the front chamber.
This special design can save space; and void the light being on the ink directly.

• Although your printers might be different from the one showing in the video, the General Rules for Installation CISS are very similar.
• If you are not confident to install the CISS in your printer, you can use refillable ink cartridges. Please visit our web site.
• Here are the General Rules for Installation CISS:
  1. Turn on the printer;
  2. Install the CISS cartridges, and push each cartridge all the way down;
  3. Adjust the length of the ink tubing until the carriage can just move freely from left to right;
  4. Organize the tubing, make sure the tubing is straight, not tangled or kinked;
  5. Replace the black caps with the clear caps on the Piano Book ink tank.
  6. Let your printer do one to two times "clean heads"
  7. Print a nozzle check or test page.
