Bleeding the Ink System
At regular intervals, normally once a day, the ink system must be bled to
prevent the build up of air in the system.
(1) Set the Pump Inhibit switch on the rear panel to position 0.
Note: The light in the switch will extinguish.
(2) Slowly open the bleed valve on the rear panel by turning the knob
counter-clockwise. Use a piece of tissue to catch any ink escaping
from the vent in the underside of the printer cabinet.
(3) Wait for 10 seconds and close the valve.
(4) Set the Pump Inhibit switch to position 1.
