Claim 16:
17. A sealing assembly comprising:
a barrier comprised of a pair of sealing curtains positioned to cover and seal an aperture, the barrier arranged so that portions of a printhead carriage are placed at separate sides of the barrier, a first curtain in the pair of sealing curtains being positioned on a first side of the printhead carriage and a second curtain in the pair of sealing curtains being positioned on a second side of the printhead carriage that is opposite the first side;
a primary pair of spools and a secondary pair of spools disposed on the opposite sides of the printhead carriage, the first curtain being attached to a first spool in the primary pair of spools and the second curtain being attached to a second spool in the primary pair of spools, the first and second curtains being spooled and unspooled by the first and second spools of the primary spools in response to movement of the printhead carriage to maintain a sealing relationship with the aperture;
a pair of protective curtains attached to the secondary pair of spools, the pair of protective curtains being positioned to overlap with the primary pair of sealing curtains to reduce particulate pollution on the primary pair of sealing curtains; and
a rotating mechanical coupling that extends between the primary pair of spools to mechanically couple, and rotate with, the primary pair of spools to synchronize rotation of the primary pair of spools that occurs with, or in response to, movement of the printhead carriage.
