Abstract
An apparatus for use servicing a printer's printhead is provided which includes a sled cam-coupled with a base so as to accommodate selected movement of the sled between a free elevation and a servicing elevation via controlled relative movement of a printer carriage. The sled and base are coupled via camming structure which is configured to yieldably oppose movement of the sled from the servicing elevation toward the free elevation. Mounted to the sled is a servicing member such as a wiper which is gradually moved into operative association with the printer's printhead upon corresponding movement of the sled into the servicing elevation.
