Abstract: An image forming apparatus includes a printer and a controller. The controller is configured to control an operational mode of the image forming apparatus to be one of a plurality of modes including a standby mode in which warming up is not performed before the next printing, and a sleep mode in which power consumption of the image forming apparatus is lower than power consumption in the standby mode and warming up is performed before the next printing. The controller is configured to set a standby time that the image forming apparatus is required to wait in the standby mode before transitioning into the sleep mode, based on a job history including the number print jobs performed on a prior day during a predetermined time period corresponding to the current time of day.

Abstract: According to one embodiment, an image forming apparatus includes a printer unit, a first controller, a power supply unit, and a second controller. The printer unit forms an image on a sheet. The first controller performs a control of shifting a state of the apparatus from a normal mode to a power saving mode. The power supply unit supplies power to the first controller and the printer unit in the normal mode and supplies power to the first controller and stops power supply to the printer unit in the power saving mode. The second controller performs a power supply control on the printer unit before performing a power supply control on the first controller when a packet received in the power saving mode includes specific information indicating a print job.

Abstract: An image forming apparatus includes an image forming unit configured to perform a printing process of forming an image on a print medium based on print data, and a processor. The processor is configured to determine whether or not the printing process has completed based on remaining print data to be printed, when the print medium is removed from a paper discharge tray in which the print medium on which the image is formed by the image forming unit is placed, and to cause a warning to be output upon determining that the printing process has not completed based on the remaining print data to be printed.
