a maintenance chassis defining tongue portions and having ends which are shaped to fit over the posts of the main body to secure the maintenance assembly in position;

a retainer element operatively engaging the chassis;

a lower molding and an upper molding operatively fast with each other to sandwich an absorbent insert between them, the moldings in turn sandwiched between the chassis and retainer element; and

a motorized drive for moving the maintenance chassis between a capped position and an uncapped position to facilitate wiping a printhead of the printer.

3. The maintenance assembly of claim 2 , wherein the maintenance chassis includes a centrally located removed portion, window portions and spring arms extending from either side of the window portions, the spring arms angled internally in the chassis and formed by pressing the sheet metal of the chassis.

4. The maintenance assembly of claim 3 , having a rigid insert which fits within the chassis to provide added rigidity to the maintenance assembly, a catch element projecting from a base of the rigid insert and extending into the centrally located removed portion of the chassis when the rigid insert is located within the chassis.

5. The maintenance assembly of claim 1 , wherein the lower maintenance molding is made from a plastic material and forms a body having closed ends and an open top, the ends of the lower maintenance molding defining air vents to facilitate ventilation of the maintenance assembly.

6. The maintenance assembly of claim 1 , wherein the absorbent insert includes a retainer insert supported on pin elements within the lower maintenance molding, the retainer insert providing a rigid support for strips of absorbent media retained therein.
