Abstract:
One information processing apparatus among a plurality of information processing apparatuses performs virus detection processing for detecting a computer virus. When a computer virus has been detected from the one information processing apparatus by the virus detection processing, the one information processing apparatus transmits an execution request to perform the virus detection processing to another information processing apparatus different from the one information processing apparatus among the plurality of information processing apparatuses.
Abstract:
A maintenance support device for supporting maintenance of an apparatus includes a communication interface configured to perform communication with the apparatus through a communication cable and to feed electric power to the apparatus; and an information obtaining portion configured to obtain from the apparatus, while the apparatus is fed with the electric power, pre-replacement individual identification information and post-replacement individual identification information for a target component for replacement work on the apparatus by communication using the communication interface.
Abstract:
A controller of a management device managing a plurality of image processing apparatuses acquires ability information and device identification information from the respective image processing apparatuses; determines, based on the ability information of the respective image processing apparatuses, as an in-charge device any one of the respective image processing apparatuses for each of a plurality of protocols predetermined; for the respective protocols, causes the in-charge device determined for the protocol to respond to a packet by multicast of the protocol on behalf of the respective image processing apparatuses; and causes one or more image processing apparatuses other than the in-charge device determined for the protocol to refrain from responding to a packet by multicast of the protocol. The respective image processing apparatuses respond to a packet by multicast of the protocol if the apparatus itself is determined the in-charge device for the protocol.
Abstract:
An image processing apparatus includes a display unit that displays a preview image of a document on a preview screen during login of a first user, a communication controller that receives a job from an external device, a determination unit that determines whether the job received from the external device is a specific type of job, and a display controller that controls display on the preview screen. When the specific type of job is received during display of the preview screen, the display controller assumes a predetermined degree or more of possibility that a second user different from the first user may approach the apparatus, and performs at least one of first display control where the preview image is automatically hidden on the preview screen and second display control where a non-display button for hiding the preview image according to a user operation is displayed on the preview screen.
Abstract:
A communication system includes a plurality of devices, a plurality of communication relay apparatuses, and a management server. If the management server that has received from a cloud server a request to access a specific device has no communication session with a specific communication relay apparatus that has control over the specific device, the management server transmits a tunnel connection request to a substitute apparatus (another communication relay apparatus different from the specific communication relay apparatus) via a communication session between the substitute apparatus and the management server. The substitute apparatus transfers the tunnel connection request to the specific communication relay apparatus and causes the specific communication relay apparatus to return from a power saving mode. The specific communication relay apparatus then establishes tunnel communication with the cloud server on the basis of the tunnel connection request to relay communication between the cloud server and the specific device.
Abstract:
A power supply control device includes a power conversion portion to convert AC power from a commercial power supply to DC, a control portion, a first communication portion connected to a network, a second communication portion connected to an image forming apparatus, and a device power supply switch arranged between the commercial power supply and the image forming apparatus. The control portion includes a mode decision portion to decide between a normal mode and a power-saving mode, a positional information acquisition portion to acquire positional information of the image forming apparatus, a sleep switch portion to open the device power supply switch, an activation portion to close the device power supply switch in response to a packet including the positional information of the image forming apparatus, a temporary storage control portion to temporarily store the packet, a packet transmission portion to transmit the packet, and a connection portion.
Abstract:
An image processing system includes: a server apparatus connected to a first network; an image processing apparatus connected to a second network; and a gateway apparatus, wherein the server apparatus includes: a transmitting unit configured to transmit job data of a job by the first communication protocol, the image processing apparatus being made to execute the job; and an adding unit configured to add content information to the job data, the content information indicating contents of the job, and the gateway apparatus includes: an analyzing unit; a determining unit; and an executing unit.
Abstract:
A relay device includes a first session establishing portion to establish a first communication session with a cloud server located outside a firewall, a second session establishing portion to establish a second communication session with a control target device located inside the firewall, a device information acquiring portion to acquire device information about the control target device, and a relay portion to relay a communication between the cloud server and the control target device. The relay portion includes an executability determining portion to determine whether the control target device can execute a process specified by a control command received from the cloud server, a suspending portion to suspend an output of the control command when the determination result is non-executable, and a proxy transmission portion operable, when the determination result becomes executable after the control command was put on hold, to transmit the control command to the control target device.
Abstract:
An MFP sets an access condition for an external device with respect to a cloud box. The access condition is transmitted from the MFP to a relay device, and is registered in a memory of the relay device. When the relay device receives an access request made by the external device with respect to the MFP serving as an internal device, the relay device determines whether to permit or deny access to the MFP by comparing the access request with the access condition. When the access is permitted, the access request is transferred from the relay device to the MFP, whereas when the access is denied, the relay device notifies the external device of it.
Abstract:
An image forming apparatus includes: a first communication unit configured to perform communication by a short-distance wireless method; a second communication unit having a broader communication range than the first communication unit; a storage unit configured to store data to which an access right of a first user is set; a connection information providing unit configured to, when a data providing command for providing the data from a first terminal device of the first user to another user is received, and an access request to the data is received from a second terminal device of a second user, transmit connection information for accessing the data to the second terminal device; and a data providing unit configured to transmit the data to the second terminal device by the second communication unit, when a transmission request of the data is received from the second terminal device based on the connection information.
