A printing apparatus for shortening the time required to read documents having a plurality of pages, while preventing the occurrence of an overflow in a storage unit.

A printing apparatus for shortening the time required to read documents having a plurality of pages, while preventing the occurrence of an overflow in a storage unit.

An image forming apparatus is provided that includes a scanning unit that performs a scanning operation of scanning each page of a document to acquire image data, and a printing unit that performs a printing operation of printing data based on the image data acquired by the scanning unit in parallel with the scanning operation by the scanning unit. The image forming apparatus further includes a control unit that controls the printing unit to stop the printing operation before the printing operation is performed with respect to all the image data acquired by the scanning unit, and controls the printing unit to resume the printing operation with respect to data that is stored in a storage unit based on the image data acquired by the scanning unit while the printing operation is stopped when the data that is stored in the storage unit reaches a first threshold value.

An image forming device that executes an image forming program for real-time mechanical control and another program, using a single cache memory for the image forming program and said another program. The image forming device includes: a cache lockdown unit that executes a cache lockdown to lock down a storage area of the cache memory that stores at least a portion of the image forming program necessary for image formation processing; and a print unit that executes the image formation processing while the storage area is locked down.

Provided is an image forming apparatus performing effective automated storage tiering. When the system control part of the CPU causes the image processing part to perform image processing of data read from the SSD having a processing speed higher than that of the HDD, the tiering control part measures a ratio of an idle time by the image processing relative to a usage ratio per unit time of the CPU, and determines a movement destination of the data.

Image forming apparatus 1 that shortens warm-up time is provided. Accordingly, image forming apparatus 1 is an asymmetrical multiprocessing configuration provided with auxiliary memory part 21 shared between main control part 10 and sub control part 11. Use area 300 is an area accessed by main control part 10. Use area 301 is an area accessed by sub control part 11. Use area specifying part 100 specifies for use area 300 and use area specifying part 101 specifies for use area 301, respectively, by use area specifying table 210. Defective area table making part 110 makes defective area table 200 by searching whether or not a defective area only for use area 300 and set as a defective area for the other area. Defective area table making part 111 makes defective area table 201 by searching use area 301, similarly, and set as the defective area for the other area.

An information processing apparatus includes a log storage and a log deleting unit. The log storage stores log information in a memory. The log information indicates a history of a process in an image forming apparatus which forms an image on recording material. The log deleting unit deletes log information from the memory among pieces of log information stored in the memory. The deleted log information satisfies a predetermined condition. The log deleting unit does not delete log information related to an abnormality occurring in the image forming apparatus, even when the log information related to the abnormality satisfies the predetermined condition.
