Abstract
The invention teaches placing labels over air diffusion vents on inkjet printheads depending upon a content of the inkjet printhead. In one embodiment, the inkjet printhead contains one or three inks in its interior and has three air diffusion vents in a lid that fluidly communicate with the interior. If the interior has one ink, a label covers the entirety of two of the three air diffusion vents to substantially prevent the two air diffusion vents from communicating with atmosphere. If the interior has three inks, a label only covers a portion of each of the three air diffusion vents and allows each to fluidly communicate with atmosphere. In this manner, single or tri-color inkjet printhead manufacturing can occur with a single lid having a multiplicity of label placement positions. The labels can have similar dimensions, dissimilar length dimensions or other.
