Image forming apparatus, network system, and control method of image forming apparatus

摘要

For update of individual firmware of an image forming apparatus by a service person through a dedicated interface, an update information file indicating a range of versions of firmware in collective update is stored. In the collective update, applicable firmware is searched based on the versions included in the update information file to search sets of applicable firmware. When the sets of the applicable firmware searched in a distribution system are acquired, collective update of the firmware is performed based on a firmware set selected from the sets.

主权项

1. An image forming apparatus comprising:
a transmission unit that transmits, to a distribution system, a first search request including version information indicating current versions of firmware of the image forming apparatus to search a set of the firmware applicable to the image forming apparatus without using an update information file; one or more processors; and at least one memory coupled to the one or more processors, the at least one memory having stored thereon, when an individual-update of firmware of the image forming apparatus is performed, the update information file including version information indicating versions of the firmware before and after the individual-update, wherein the individual-update is a manual update of a part of the firmware of the image forming apparatus, and instructions which, when executed by the one or more processors, cause the image forming apparatus to:
set, to the update information file, flag information indicating a search option of a set of the firmware applicable to the image forming apparatus;acquire, from the distribution system, a set of applicable firmware found by using the version information included in the first search request in the distribution system and that performs an update using the acquired set of the applicable firmware; anddetermine whether or not the update information file is stored if a set of applicable firmware corresponding to the version information included in the first search request is not obtained from the distribution system, wherein the transmission unit transmits, to the distribution system, a second search request including version information included in the update information file if it is determined that the update information file is stored and the flag information indicates, as the search option, to use the version of the firmware before the individual-update for the search.
