Abstract:
1. An image forming apparatus comprising: a first storage for storing basic settings of the apparatus; an input portion for receiving input of a revised setting for revising the basic settings stored in the first storage; a second storage for storing the revised setting input through the input portion; a third storage for storing the basic settings before revision that have been stored in the first storage; and a controller, wherein the controller performs the steps of: determining whether the input revised setting falls within a predetermined range; rewriting the basic settings stored in the first storage with the revised setting stored in the second storage when the revised setting falls within the predetermined range; and, rewriting the settings stored in the first storage with the basic settings stored in the third storage when the revised setting falls out of the predetermined range, wherein a first setup range of the basic setting is defined as a predetermined range within which a setting is permissible as the basic setting, and the controller will not rewrite the basic settings stored in the first storage when the input revised setting falls out of the first setup range, and a second setup range of the basic setting is defined as a range within which the basic setting is practically set, and the controller further performs the steps of: temporarily rewriting the basic settings stored in the first storage with the revised setting stored in the second storage when the input revised setting falls within the first setup range; keeping the revised setting, stored in the first storage by revision as is when the revised setting falls within the second setup range; and rewriting the revised setting stored in the first storage with the basic setting stored in the third storage when the revised setting, stored in the first storage by revision falls out of the second setup range.
