Abstract:
Provided is an image forming apparatus that prevents the image forming apparatus being operated in a state where a user setting value is changed by a maintenance worker before a user is aware of the change without lowering efficiency of a maintenance work. The image forming apparatus according to the present disclosure is an image forming apparatus whose operation is controlled based on a setting value, and the setting value contains an operation control user setting value set by an administrator user having administrator authority. The image forming apparatus includes a maintenance work processing part that prohibits a general user having no administrator authority from using the image forming apparatus until the administrator user approves the operation control user setting value changed by the maintenance worker if the operation control user setting value is changed by the maintenance worker having the administrator authority.
Abstract:
Provided is a data setting system that has an image forming apparatus provided with an image reading part, and the communication terminal apparatus provided with a light irradiating part. The image forming apparatus is provided with an optical-communication receive part and an optical-communication execution part. The optical-communication receive part receives an external light signal by using an image reading part. The optical-communication execution part performs a setup of the data corresponding to the received light signal. The communication terminal apparatus is provided with an optical-communication sending part. The optical-communication sending part sends the light signal corresponding to a setup of data using a light irradiating part.
Abstract:
Provided is an image forming apparatus that is able to prevent a security environment from being changed due to maintenance work without an administrator user noticing. The image forming apparatus is an image forming apparatus that performs image formation, and includes a setting receiving unit that receives settings such as settings related to maintenance of the image formation, settings related to security, and an administrator user setting. The setting receiving unit receives all of the settings by a maintenance worker when the administrator user setting is unset, and prohibits receiving settings related to security by the maintenance worker when the administrator user setting is set.
Abstract:
The print pattern forming unit forms plural comparative print patterns on a sheet by reference print patterns corresponding to every sheet feed cassette associated with different reference positions for every sheet feed cassette. The displacement amount calculation unit reads the comparative print patterns on the sheet, and calculates displacement amounts between the reference positions and comparative positions of the read comparative print patterns corresponding to the reference positions. The correction unit corrects the print position of the sheet conveyed from the sheet feed cassette based on the displacement amount for every sheet feed cassette.
