Patent Images
1. An image forming apparatus, comprising:
- a plurality of processing units wherein each processing unit processes data for forming an image;
a control unit that communicates with each of said plurality of processing units directly, or indirectly through another one or more of said processing units;
an update program acquiring unit that acquires update programs configured to update corresponding programs of said processing units; and
a program updating unit that updates the corresponding programs of said processing units in a prioritized update order in which the processing unit or processing units which are indirectly communicated with by said control unit are assigned a highest priority so as to be updated before any of said processing units directly communicated with by said control unit.

Abstract
An image forming apparatus is disclosed that includes one or more processing units, a control unit, an update program acquiring unit that acquires an update program for updating programs of the processing units and the control unit, and a program updating unit that updates the programs of the processing units in the order of the number of the other processing units through which the control unit communicates with each of the processing units. The order in which the processing units are updated is determined based on the number of other processing units via which each of the processing units communicates with the control unit.

32. A method of updating a plurality of programs corresponding to a plurality of processing units associated with an image forming apparatus that processes data for forming an image, the image forming apparatus including a control unit that communicates with each of said plurality of processing units directly, or indirectly through another one or more of said processing units, the method comprising:
-
acquiring update programs configured to update at least the programs corresponding to a plurality of processing units; and updating each of the programs corresponding to at least the plurality of processing units in a prioritized update order in which the processing unit or processing units which are indirectly communicated with by said control unit are assigned a highest priority so as to be updated before any of the processing units directly communicated with by said control unit. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
