4.
Press the Raise Carriage button and then use the maintenance suction nozzle to remove any
excess ink from the printhead that you purged.
5.
Close the maintenance station door.
6.
In the ink bay, reconnect the ink bag coupler of the target ink bag to re-initiate ink fill.
7. Locate the bleed tube valve on the top of the ink filter you are going to bleed (the cap that holds it
in place indicates the color of the ink line into that filter).
8. Attach the syringe to the bleed port and open the stopcock.
If you want to reuse the syringe, start with the lighter ink colors first. Darker inks will stain the
clear plastic wall of the syringe and make it difficult to see the ink as it comes in.
9.
Pull the plunger out until ink is seen in the syringe.
If there is excessive air, more than one syringe full of air may be extracted. In this case, close the
stopcock before disconnecting the syringe and expelling the air.
10. After the air has been fully withdrawn from the filter there will be a noticeable increase in the
force required to pull on the syringe, and ink will begin to flow into the syringe.
11.
Once ink has been drawn into the syringe (it will want to spring back due to the vacuum in the
syringe), release the plunger slowly, close the stopcock, disconnect the syringe, and carefully
discard the ink into a waste bucket.
