An image forming apparatus and method for determining a response delay time for maintaining a long polling connection are provided. In an example, the image forming apparatus includes a communication device to communicate with an external device, a processor, and a memory storing instructions executable by the processor. The processor may execute the instructions to request the external device for a response about whether a job to be performed by the image forming apparatus is present based on a response delay time for long polling the external device by the image forming apparatus. The processor may also execute the instructions to detect an error from the response, adjust the response delay time, and determine a final response delay time for maintaining connection of the long polling by re-adjusting the adjusted response delay time based on a result of performing the long polling based on the adjusted response delay time.

A system for tracking the location of an electronic device includes an electronic device and a wireless location tag. The wireless location tag includes a microcontroller unit, and a modular connector interface configured to be communicatively coupled to a port of the electronic device. The wireless location tag is configured to establish an Internet connection to one or more backend electronic devices in response to detecting that the wireless location tag has been communicatively coupled to the port of the electronic device, obtain identifying information that is associated with the electronic device, and identify tag identifying information associated with the wireless location tag. The wireless location tag is also configured to send one or more instructions to the one or more backend electronic devices via the Internet connection, and send one or more ping messages to the one or more backend electronic devices.

A CPU of a printer requests a first external device to supply electric power via a first interface through communications according to the USB standard. When the CPU determines that the requested electric power is to be unsupplied from the first external device, the CPU requests a second external device to supply the electric power via a second interface.

An apparatus that executes a job, broadcasts a wireless signal prior to establishing a connection by wireless communication with an external apparatus. The wireless signal includes information relating to the apparatus, by which it can be identified whether execution of a job by the apparatus is possible, in a predetermined packet.

A CPU of an MFP receives battery information from a first external device via a first interface, determines whether a total amount of electric power supplied to a plurality of interfaces from a power supply is maintained, and reduces an amount of the electric power supplied to the first external device via the first interface in a case where determining that the first external device has no battery based on the battery information in response to determining that the total amount of the electric power supplied to the plurality of the interfaces from the power supply is not maintained.

A document processing system configured to communicate with a server includes at least one memory that stores instructions, and at least one processor that executes the instructions to receive a scanned document from an image processing apparatus, transmit the received scanned document and a processing request for processing the scanned document to the server, manage a processing status regarding processing of the received scanned document, and issue a notification to a user in a case where a predetermined processing time regarding the processing of the scanned document passes based on the managed processing status.

A recording device includes a recording unit configured to perform recording on media, a main body provided with the recording unit, and a medium accommodation unit configured to be attached to and detached from the main body and configured to accommodate the media, wherein the medium accommodation unit includes a first region configured to accommodate a pre-recording medium before being subjected to recording by the recording unit, and a second region configured to accommodate a recorded medium after being subjected to the recording by the recording unit.

A system for tracking the location of an electronic device includes an electronic device and a wireless location tag. The wireless location tag includes a microcontroller unit, and a modular connector interface configured to be communicatively coupled to a port of the electronic device. The wireless location tag is configured to establish an Internet connection to one or more backend electronic devices in response to detecting that the wireless location tag has been communicatively coupled to the port of the electronic device, obtain identifying information that is associated with the electronic device, and identify tag identifying information associated with the wireless location tag. The wireless location tag is also configured to send one or more instructions to the one or more backend electronic devices via the Internet connection, and send one or more ping messages to the one or more backend electronic devices.

A terminal device includes a communicator capable of communicating with a plurality of image forming apparatuses capable of switching an operation mode between an energy-saving mode and a normal mode, and a controller, wherein the controller, from the plurality of image forming apparatuses via the communicator, receives information of each image forming apparatus including the operation mode, based on the information of each image forming apparatus, displays states of the operation modes of the image forming apparatuses, and sends a request signal, which switches the operation mode, via the communicator to the image forming apparatus selected from among the displayed image forming apparatuses.

A mobile terminal improved in operability concerning fax transmission. A CPU of the mobile terminal sets information indicative of a fax transmission destination, sets reading and transmission information concerning fax transmission and original reading, and sends a request for fax transmission, to an image forming apparatus. When a response notifying capability of fax transmission is received from the apparatus, the CPU causes a message for prompting a user to set an original, to be displayed on a display section. When the original has been set and an instruction for fax transmission from the user is received, the CPU sends an instruction for reading the original and executing fax transmission, together with the transmission destination information, and the reading and transmission information, to the apparatus. The CPU causes a result of fax transmission by the apparatus to be displayed on the display section.
