A method of controlling a printer is disclosed, the printer including a number of print heads extending across a print zone, and each print head including at least one nozzle array extending in a direction of a print head axis. Each nozzle array comprises a center section of nozzles and side sections of nozzles, wherein the side sections of neighboring nozzle arrays overlap defining an overlap region and the center sections of the nozzle arrays define non-overlap regions. The method includes: printing a test pattern using at least two nozzle arrays, the test pattern comprising an interferential-type pattern printed by the side sections of the nozzle arrays in the overlap region and a reference pattern printed by the center sections of the nozzle arrays in the non-overlap regions; detecting characteristics of the printed test pattern; comparing the characteristics of the printed test pattern in the overlap region and in the non-overlap region; and deriving information concerning the alignment of nozzle arrays from the comparison

A manufacturing method of a liquid ejection head including manufacturing a flow path constituting member for supplying a liquid to an ejection module, the manufacturing a flow path constituting member including using a metal mold which is constituted of a fixed mold and a movable mold, the manufacturing a flow path constituting member including: a first step of molding a first member, a second member, and a third member independently at locations different from each other in the metal mold, the first member, the second member, and the third member constituting the flow path constituting member; a second step of joining the first member and the second member in a specific manner; and a third step of joining the second member and the third member in a specific manner.

A liquid ejecting apparatus includes a head unit that includes a nozzle that ejects a liquid, a control circuit that outputs a control signal that controls an operation of the head unit, a power supply circuit that supplies a power supply voltage to the head unit, and a liquid container that stores the liquid. The head unit includes a first terminal to which the control signal is input, a second terminal to which the power supply voltage is supplied, and a liquid supply port to which the liquid is supplied, the first terminal and the second terminal are located side by side along a first direction, and the second terminal is located between the first terminal and the liquid supply port in a second direction intersecting the first direction.

Provided is a liquid ejecting head which includes head bodies aligned in a direction of liquid ejection surface thereof, a flow-path member in which distribution flow path is provided to supply liquid to the head bodies, and flexible wiring substrates connected to the head bodies. The distribution flow path extends in the first direction. In addition, the flexible wiring substrates adjacent in the first direction overlap when viewed from the first direction. The distribution flow path is disposed in an area on one side with respect to the flexible wiring substrates, in a direction perpendicular to the first direction in the liquid ejection surface.

A liquid ejection head includes: head units arranged in a first direction; first individual heat dissipators each corresponding to one of the head units and disposed on a first side of the head unit in a second direction; and a first common heat dissipator disposed on the first side of the head units in the second direction. The first common heat dissipator extends in the first direction and shared among the head units. Each head unit includes: a unit body including an actuator; and a first driver integrated circuit disposed on the first side of the unit body in the second direction. Each of the first individual heat dissipators is disposed between the first driver integrated circuit and the first common heat dissipator of the head unit so as to be in thermal contact with the first driver integrated circuit and the first common heat dissipator.

One example provides a printhead including a plurality of printhead dies, each printhead die including at least one crack sense resistor. At least one analog bus is connected to each printhead die, the at least one analog bus to output voltages to facilitate a printer controller to determine whether at least one of the printhead dies is cracked.

A liquid ejection head includes a pressure chamber, an upstream channel, a downstream channel, a pump, an inflow channel, and a bypass channel. The upstream channel communicates with the pressure chamber to supply the liquid to the pressure chamber. The downstream channel communicates with the pressure chamber. The pump communicates with the upstream channel and the downstream channel to cause the liquid in the downstream channel to flow into the upstream channel. The inflow channel communicates with the upstream channel to cause the liquid to be supplied to the pressure chamber to flow into the upstream channel. The upstream channel and the downstream channel communicate with each other through the bypass channel without the pressure chamber being between the upstream channel and the downstream channel. Part of the liquid flowing from the upstream channel into the bypass channel flows into the pressure chamber through the downstream channel.
