Maintenance apparatus and method for vaporizing device

A method for maintaining the cleanliness of an ejection head in a fluid ejection and vaporization device having a source of air flow through the fluid ejection and vaporization device comprising:

• providing, within the fluid ejection and vaporization device, a movable wiper blade, the wiper blade being attached to an arm on one end of the arm, wherein a distal end of the arm is attached to an air operated mechanism for moving the arm and for causing a sweeping movement of the wiper blade over an ejection head in the fluid ejection and vaporization device, and
• causing a flow of air through the fluid ejection and vaporization device in an amount sufficient to cause movement of the wiper blade in a sweeping motion from a first position to a second position across the ejection head.
