A recording device includes a transport belt, a recording unit, a destaticization unit that destaticizes a medium, a cleaning unit that cleans the transport belt, and a control unit. The control unit rotates the transport belt while the recording unit is at a separation position, until a contact portion of the transport belt passes through the cleaning unit, the contact portion contacting with the destaticization unit restored from a retraction position to a destaticization position.

A liquid ejecting apparatus includes: a liquid ejecting head including a nozzle that ejects liquid, a pressure chamber, and a piezoelectric body that applies pressure to the liquid in the pressure chamber to eject the liquid from the nozzle; a voltage application circuit configured to apply a voltage to the piezoelectric body; and an acquisition section configured to acquire a degree of deterioration of the piezoelectric body, based on information regarding an integral value of a current generated when the voltage applied to the piezoelectric body is gradually changed from a first voltage to a second voltage.

An object of the present disclosure is to provide a recycling method of a cartridge that has the potential to contribute to the achievement of a sustainable society, such as a decarbonized society/circular society. The recycling method of the cartridge includes: performing electrical evaluation to evaluate an electrical characteristic of a printing element substrate by supplying electric power to the printing element substrate from a wiring substrate; performing outer appearance evaluation to evaluate an outer appearance of the cartridge based on the number of ejection ports having a problem out of multiple ejection ports; and determining whether to recycle the cartridge based on a result of the electrical evaluation and a result of the outer appearance evaluation.
