The present specification describes a manifold for a fluid ejection system. The manifold includes a rotational connector on a first side surface, a plurality of pen interconnects on a bottom surface of the manifold, and a sliding surface on a top surface of the manifold. The sliding surface is to accommodate a fluidic interface. Sliding the fluidic interface along the sliding surface extends needles from the fluidic interface through the plurality of pen interconnects into a plurality of pens.

In a method of controlling a liquid ejecting apparatus, where the liquid ejecting apparatus includes a pressure chamber that communicates with a nozzle that ejects a liquid, a drive element that changes a pressure of the liquid in the pressure chamber, and a drive circuit that supplies the drive element with an ejection pulse that generates a change in the pressure that ejects the liquid from the nozzle, the method includes specifying a viscosity of the liquid in the nozzle and a surface tension of the liquid in the nozzle from a residual vibration when the pressure of the liquid in the pressure chamber is changed, and controlling a waveform of the ejection pulse according to the viscosity and the surface tension.

A transportation portion includes an apparatus body, a cover, first and second path formation portions, and a movement portion. The apparatus body has a transportation path including a downward path and an upward path having portions located at the same level in the Z direction. The cover covers and uncovers the transportation path. The first path formation portion is movable to a first position and to a second position. The second path formation portion defines the upward path and defines the downward path with the first path formation portion. The movement portion moves the first path formation portion in response to opening or closing of the cover. The first path formation portion is positioned in a movement area during a closed state. The movement portion moves the first path formation portion to the second position when the cover is opened and to the first position when the cover is closed.

A liquid ejecting system includes a liquid ejecting head having a nozzle ejecting liquid, a supply channel communicating with the nozzle, and a recovery channel communicated with the nozzle, and circulates the liquid in the liquid ejecting head through the supply channel and the recovery channel. The supply channel includes a pressurizing section and a first buffer mechanism disposed between the nozzle and the pressurizing section. The recovery channel includes a decompression section and a second buffer mechanism disposed between the nozzle and the decompression section. The first buffer mechanism is configured to increase a buffer capacity as the supply channel is pressurized. The second buffer mechanism is configured to reduce a buffer capacity as the recovery channel is decompressed.
