How to Change Ink Filters - How to Bleed an Ink Filter

Procedure

Open the ink purge valve of the target color to bleed and make sure the valves of the three (or four) other colors are closed.
Yellow Purge Valve Open
Click on the ink status icon located in the top right corner of the Print Job Control screen of the printer software to monitor the ink status.
Press the Purge button (switch 1 on the right) to initiate an ink purge. Repeat this step until the ink status window shows an Ink Low condition for the target color.
Maintenance Station Buttons
Press the Raise Carriage button (switch 2, middle) and then use the maintenance suction nozzle to remove any excess ink from the printhead that you purged.
Close the maintenance station door.
In the ink bay reconnect the ink bag coupler of the target ink bag to re-initiate ink fill.
Place a lint-free cloth below the bleed tube of the target ink filter to catch any ink.
Turn the valve shutoff lever so that it is parallel to the bleed tube to open the valve.
Keep the cloth close as you watch the open bleed tube. As soon as you see ink appear in the open end of the bleed tube, flip the shutoff lever back to the perpendicular closed position (this may take a few minutes, depending on the amount of air in the filter since the ink pump is only active for a brief period every 5 seconds). Ignore the residual ink that is already in the bleed tube.
