摘要： Among other things, an apparatus for use in fluid jetting is described. The apparatus includes a printhead including a flow path and a nozzle in communication with the flow path that has a first end and a second end. The apparatus also includes a first container fluidically coupled to the first end of the flow path, a second container fluidically coupled to the second end of the flow path, and a controller. The first container has a first controllable internal pressure and the second container has a second controllable internal pressure. The controller controls the first internal pressure and the second internal pressure to have a fluid flow between the first container and the second container through the flow path in the printhead according to a first mode and a second mode. In either mode, at least a portion of the fluid flowing along the flow path is delivered to the nozzle when the nozzle is jetting. The first mode has the first internal pressure higher than the second internal pressure and the second mode has the second internal pressure higher than the first internal pressure. The fluid flows from the first container to the second container according to the first mode and flows from the second container to the first container according to the second mode.

摘要： An attachment is mounted on a cartridge holder of a printer as a replacement of an ink cartridge. An ink outlet member having a link passage is separably secured to an attachment body. Ink is supplied from the exterior to the ink outlet member through an ink supply tube. When the attachment is mounted on the cartridge holder, a downstream end of the ink outlet member is positioned with respect to and connected to an ink supply needle of the printer. Accordingly, the attachment is easily and quickly installed in a liquid ejection apparatus. This reduces costs and makes it easy to use the attachment.
