An image processing apparatus includes a first processor and a second processor. The first processor has a power saving function. The second processor is configured to consume less power than the first processor during operation. When the first processor stopped by the power saving function is activated in response to reception of a network packet, the first processor determines an operating frequency of the first processor in accordance with a type of the network packet.

An image forming apparatus operates in two modes of an energy saving mode and a normal mode. The image forming apparatus includes a shared memory that is capable of being referenced by a network interface card, which is detachably connected to the image forming apparatus, in the energy saving mode and the normal mode of the image forming apparatus; and an apparatus information saving unit that, when an apparatus state of the image forming apparatus is changed, saves image forming apparatus information regarding the apparatus state of the image forming apparatus in the shared memory. The network interface card includes an apparatus information acquisition unit that acquires the image forming apparatus information from the shared memory.

Image forming apparatus for reducing power consumption using a commonly accessible shared memory

An image forming apparatus includes a computing unit to compute an amount of ink to be used to record raster data if a remaining amount of ink reaches a predetermined amount, and a recording control part to enable the recording if the remaining amount of ink is greater than the amount of ink computed by the computing unit. The recording control part disables the recording if the remaining amount of ink is less than or equal to the amount of ink computed by the computing unit.

Image forming apparatus, image formation enabling or disabling method, and computer-readable storage medium

An image forming apparatus includes an image process control unit processing an image data and generating a control signal, and a drive pattern generation unit to generate a drive pattern to drive a recording head, based on the control signal, the drive pattern generation unit generating at least a first drive pattern and a second drive pattern which is different from the first drive pattern. The drive pattern generation unit sets a reference potential of the second drive pattern as a target reference potential and applying a pattern end of the first drive pattern to one of a pull-up pattern and a pull-down pattern operation before the second drive pattern is performed, wherein the drive pattern generation unit generates one of the pull-up pattern and the pull-down pattern based on a slope value obtained by comparing the target reference potential and the end potential.

Image processing apparatus, image processing method and computer-readable recording medium of image processing method

An image forming apparatus whereby recording liquid is jetted onto a recording medium so that an image is formed, the image forming apparatus includes an operations part configured to operate the apparatus in a predetermined special mode different from a normal mode in a case where a machine number stored in advance is a specific character string.
