摘要： A base frame, which supports head modules, is provided with a first storage device that stores information about the positions of support reference points of the head modules. The head module is provided with a second storage device that stores information about the positions of nozzles of the head module. An inkjet recording device is provided with a third storage device that stores information about the positions of the nozzles of the respective head modules provided on the base frame. When the head module is replaced, information about the correction of a position, which is required to mount the replaced head module at a normal position, is generated based on the information stored in the first storage device, the information stored in the second storage device, and the information stored in the third storage device. The mounting position of the replaced head module is corrected based on the generated information.

摘要： There is disclosed a solid semiconductor element which very efficiently detects information about a liquid and bidirectionally exchanges the information with the outside. The solid semiconductor element is disposed in a liquid container, and includes at least energy converting unit, information acquiring unit, and information communicating unit. The energy converting unit converts an electromotive force from the outside to a power, and operates the information acquiring unit and information communicating unit. The information acquiring unit acquires the information about the liquid in which the solid semiconductor element is disposed from the liquid, and the information communicating unit transmits the information acquired by the information acquiring unit to the outside.

摘要： An inkjet printer includes a body housing a print engine. The print engine includes a transport mechanism configured to transport print media and a printhead assembly configured to print upon the print media. The transport mechanism includes a motor which can be driven in one direction when picking an endmost sheet of print media from a stack of print media and driven in another direction when transporting the picked print media during printing. A retractable cover is pivotally mounted relative to the body and can be pivoted to form a sheet feeder in which the stack can be located. A capping mechanism is configured to cap the printhead assembly.
