摘要:
An image forming apparatus includes a suction controller to seal a nozzle face of a recording head with a cap and drives a suction device to suck liquid from the head to perform sucking operation. The dummy ejection controller ejects, from the head, droplets not contributing to image formation to perform dummy ejection. The first tinier measures a first elapsed time after the dummy ejection. The second timer measures a second elapsed time after the sucking operation. A liquid discharge amount of the sucking operation is set to be greater than that of the dummy ejection. When the first elapsed time is equal to or greater than a first threshold time, the dummy ejection controller performs the dummy ejection. When the second elapsed time is equal to or greater than a second threshold time which is greater than the first threshold time, the suction controller performs the sucking operation.

A liquid discharge apparatus includes a liquid discharge head configured to discharge a liquid, a sub tank configured to hold the liquid to supply the liquid to the liquid discharge head, a liquid cartridge configured to hold the liquid to be supplied to the sub tank, a supply channel configured to connect the sub tank and the liquid cartridge to supply the liquid from the liquid cartridge to the sub tank in a supply direction, a first channel opening-and-closing mechanism disposed in the supply channel to switch connection and disconnection of the supply channel, a second channel opening-and-closing mechanism disposed downstream of the first channel opening-and-closing mechanism in the supply direction in the supply channel, and circuitry configured to operate the first channel opening-and-closing mechanism to connect the supply channel, and operate the second channel opening-and-closing mechanism to feed the liquid from the liquid cartridge to the sub tank.

A performance adjustment apparatus connected to an information processing apparatus includes a performance adjustment unit that controls operation processing performance of an operation processing apparatus of the information processing apparatus based on a specified performance adjustment value, a performance type list information management unit that manages performance type list information comprising a plurality of pairs of a performance type and a performance adjustment value, a performance type specification unit that specifies a performance type in the performance type list information managed by the performance type list information management unit and changes the performance type, a performance adjustment value setting unit that obtains a performance adjustment value corresponding to the performance type specified by the performance type specification unit from the performance type list information management unit, and sets the obtained performance adjustment value in the performance adjustment unit.

An image forming apparatus includes an output unit, a pair of output rotary bodies, and a controller. A sheet having an image formed thereon is discharged to the output unit. When plural sheets are sequentially discharged to the output unit, the controller controls overlapping output operation to, with a trailing end portion of a preceding sheet of the plural sheets being held by the pair of output rotary bodies, feed a subsequent sheet of the sheets to between the pair of output rotary bodies to overlap a leading end portion of the subsequent sheet with the trailing end portion of the preceding sheet. With the leading end portion of the subsequent sheet overlapped with the trailing end portion of the preceding sheet, the controller controls the pair of output rotary bodies to rotate to discharge the preceding sheet to the output unit.
