    摘要： When a mail server 31 and a mail server 32 are in a failover state, switches 21, 22 select communication paths E, F. A temporary save server 50 stores email received from a mail reception server 10 during the failover in a disk storage 60, and after the completion of the failover, transmits to a mail server (e.g., mail server 32) that has been switched to function as a primary system an email stored in disk storage 60 and a write request for a disk storage 40. Mail server 32, upon receiving an email and a write request from temporary save server 50, stores the received email to disk storage 40 to update stored content.

    摘要： An image forming apparatus includes a liquid discharge device and processing circuitry. The liquid discharge device includes at least one nozzle group, where N represents an integer, to discharge liquid. The processing circuitry causes the first nozzle group to discharge in a first scan, causes the second nozzle group to discharge in a second scan, and causes the N-th nozzle group to discharge in an N-th scan to form a complete image. The processing circuitry, with respect to an image completion rate indicating a rate of an image formed by each of the first nozzle group to the N-th nozzle group in the complete image, sets the image completion rate of a portion of the first nozzle group adjacent to the second nozzle group in the sub-scanning direction to be not higher than the image completion rate of any one of the second nozzle group to the N-th nozzle group.

    摘要： A liquid discharge apparatus includes a liquid discharge head having at least one nozzle array including a plurality of nozzles lined in a nozzle array direction; a two-dimensional image sensor to capture an image formed by the liquid discharge head; and circuitry. The circuitry is configured to divide the nozzles into a plurality of nozzle units; form a pattern including a plurality of unit patterns with liquid discharged from the nozzle units, respectively; and detect a defective nozzle based on a captured image of each of the unit patterns. The unit patterns are arranged in a staggered manner. Each unit pattern is smaller in size than an image capture range of the two-dimensional image sensor. Each unit pattern includes a number of columns of lines extending in a direction perpendicular to the nozzle array direction, and the number of columns is not smaller than twice the number of nozzle arrays.
