Abstract
An apparatus is to selectively purge a desired fluid-jet printhead of a number of fluid-jet printheads of a page-wide array fluid-jet device. The apparatus includes a purging insert movably locatable within a fluid channel of the page-wide array fluid-jet device. The fluid channel is to supply fluid to the fluid-jet printheads during normal operation of the page-wide array fluid-jet device. The apparatus includes a movement mechanism operatively coupled to the purging insert to move the purging insert within the fluid channel incident to the desired fluid-jet printhead. The apparatus includes a pressurizing mechanism fluidically coupled to the purging insert to pressurize fluid. The purging insert is to deliver the fluid as pressurized by the pressurizing mechanism to the desired fluid-jet printhead to purge the desired fluid-jet printhead.
