Abstract

A capping assembly for capping a pagewidth printhead of an inkjet printer comprising: a body configured to extend the length of the printhead; a capping element housed within the body and having a rim portion adapted to cap at least a portion of the printhead; a displacement assembly housed within the body for moving the capping element between a first position where the rim portion of the capping element extends from said body, and a second portion where the portion of the capping element is contained within the body; wherein, the displacement assembly is controlled by an electromagnet which determines the position.

Claims13

Dependent claims

A capping assembly of an inkjet printhead cartridge for capping a pagewidth printhead of the inkjet printhead cartridge, the capping assembly comprising:

a capping element having a rim portion adapted to cap at least a portion of the printhead;
a displacement assembly for moving the capping element between a first position at which the rim portion of the capping element caps the printhead, and a second position at which the rim portion of the capping element is spaced from the printhead;
wherein, the printhead cartridge is configured to be removably engaged with a printer cradle unit so that the displacement assembly is controlled by an electromagnet of the cradle unit which determines the position.

Dependencies are inferred from the claim text.
