Abstract
An apparatus for maintaining an ambient condition about a marking module. The apparatus includes a substantially air impervious enclosure defining a chamber having the marking module disposed therein. An air flow source supplies air to the chamber, and sensors respond to the amount of air flow to control the air flowing from the air source.
Claims16
An apparatus for maintaining an ambient condition about a marking module, including:
- a substantially air impervious enclosure defining a chamber having the marking module mounted therein;
- an air source, coupled to said enclosure, for supplying air to the chamber;
- means for sensing the air flow in the chamber of said enclosure to control the air flowing from said air source to the chamber;
- and
- an air dispersion device, coupled to said air source and said sensing means, for controlling the air flow to the chamber of said enclosure, said dispersion device includes a plurality of diffusers, and a plurality of valves coupled to said plurality of diffusers, said valves being responsive to said sensing means for controlling air flow.
