Clamping and Removing the Old Sac

Move the carriage to the maintenance position. Clamp the ink tube firmly near the ink tank to prevent ink from flowing out. Gently pinch the sides of the old sac shell and lift it upward slowly.

Dispose of the old sac in a sealed bag.

Installing and Priming the New Sac

Connect the ink tube to the new sac, pushing it firmly onto the barb fitting until fully seated. Fill the new sac with ink using a syringe—draw ink slowly from the bottom inlet until the sac is 70–80% full and no air bubbles remain.
