The piezoelectric element includes multiple drive portions arranged in a first direction; multiple non-drive portions; and multiple dummy drive portions at each portion between the multiple drive portions and the multiple non-drive portions in the first direction; a first electrode configured to supply the driving signal to the multiple drive portions; and a second electrode configured to supply the common-electrode signal to the multiple drive portions. The flexible circuit board includes a third electrode configured to supply the common-electrode signal to the multiple drive portions. Each of the multiple non-drive portions and the multiple dummy drive portions include a common-electrode joint connected to the third electrode of the flexible circuit board.

摘要： To prevent effective print speed from being lowered, a counter is provided for each of a plurality of print hammers. A number of times a print hammer is driven during one print phase having a predetermined period of time is counted by the counter. The counted value is compared with a reference value, and when the counted value has reached the reference value during the print phase, driving of the print hammer is halted until the end of the print phase. A reference value is changed based on the number of times the print hammer is driven during a previous print phase immediately before the present print phase. The reference value represents an allowable number the print hammer can be driven during each of successive print phases.

摘要： To prevent undue elevation of temperature in a hammer assembly but to maintain the maximum printing speed, when a scheduled number of drivings at which print hammers are to be driven during one scan of a manner bank which follows the currently performing scan, exceeds a first reference number, one dot line printing is completed with a plurality of scans of the hammer bank so that dot line print density in each scan of the hammer bank does not exceed, for example, 35%. If, however, high density printing exceeding 25% continues for an extended period of time more than one scan time, the printing operation is temporarily halted.

摘要： A liquid discharge head includes a nozzle plate, a common chamber substrate, a channel substrate, a first bridge, and a second bridge. The nozzle plate has multiple nozzles from each of which a liquid is dischargeable in a first direction. The common chamber substrate has a supply-side common chamber having a first supply sidewall and a second supply sidewall in a second direction, and a collection-side common chamber adjacent to the supply-side common chamber in the second direction. The collection-side common chamber has a first collection sidewall and a second collection sidewall in the second direction. The channel substrate is laminated over the common chamber substrate. The first bridge is disposed between the first supply sidewall and the second supply sidewall to bridge the supply-side common chamber. The second bridge is disposed between the first collection sidewall and the second collection sidewall to bridge the collection-side common chamber.
