The fluidic die also comprises an actuation signal generator, coupled to the multiplexer, to provide the multiplexer with a plurality of actuation signals. The fluidic die also includes actuation signal mapping logic to control the multiplexer and the actuation signal generator based on one of a plurality of stored modes, each mode mapping the plurality of actuation signals to the plurality of actuators.

A liquid discharge apparatus is provided that includes a discharge unit configured to discharge a liquid onto a medium, a support portion configured to support a portion of the medium, the liquid being discharged from the discharge unit onto the portion of the medium, a housing including therein the discharge unit, a humidity detection unit configured to detect a humidity, and a display control unit configured to display an indication prompting adjustment of a temperature or humidity when the humidity detection unit detects a humidity less than a lower limit value, and configured to display an indication prompting adjustment of a temperature or humidity when the humidity detection unit detects a humidity exceeding an upper limit value greater than the lower limit value.

An ejection surface extends in a first direction as a scanning direction and a second direction orthogonal to the first direction and is externally exposed. A plurality of nozzles opens at the ejection surface. A plurality of partial channels is located inside the ejection surface, and at bottom surfaces on a side of the ejection surface, the nozzles open. The plurality of nozzles is arranged in a direction intersecting with the first direction in plural rows to constitute a plurality of nozzle rows. The number of the nozzles arranged in each row is greater than the number of the plural rows. Between the nozzles in each nozzle row, the nozzles in other nozzle rows appear as seen in the first direction. A position of openings in the bottom surfaces of the partial channels differs across at least some of the nozzles in each nozzle row.

An image recording apparatus includes a recording head including a plurality of nozzles from which ink is ejected, a memory, and one or more hardware processors coupled to the recording head and the memory. The one or more hardware processors are configured to: determine, for each of the plurality of nozzles, whether a position of the corresponding nozzle is a position to eject ink; determine whether a successive ejection operation is necessary for a nozzle out of the plurality of nozzles, whose position is determined as the position to eject ink; and cause ink to be successively ejected at the position to eject ink at a predetermined successive ejection frequency from the nozzle that is determined to have the necessity of the successive ejection operation.

A recording apparatus that performs recording on a recording medium includes a low temperature marker that, depending on a change in temperature, changes a color state to a low-temperature first color state or to a low-temperature second color state different from the low-temperature first color state, and a surface on which the low temperature marker is disposed. The low temperature marker has a characteristic of indicating the low-temperature second color state when a temperature of the low temperature marker is higher than at least the low-temperature first threshold temperature after reached a temperature lower than or equal to a low-temperature first threshold temperature from an initial state indicating the low temperature first color state.
