An apparatus, system, and method for displaying an antenna location of a communication terminal, receives, from a user carrying and operating the communication terminal, an instruction that causes the communication terminal to establish a non-contact communication with a counterpart communication device via an antenna provided in the communication terminal, and controls a display of the communication terminal to display location guide information indicating a location of the antenna in the communication terminal, the location guide information to be used for assisting the user in identifying a section of the communication terminal to be brought closer to the counterpart communication device to start establishing the non-contact communication with the counterpart communication device.

Apparatus, method, and system for displaying antenna location of communication terminal, and recording medium

An information processing system includes a server, and a terminal device communicable with the server via a network. The terminal device includes a display, an image capturing device to capture a marker image and a first image formed on a recording medium, the marker image indicating a condition of displaying information on the display, and circuitry to extract an identifier of the marker image from the captured marker image, transmit identification information of the terminal device or user and the extracted identifier of the captured marker image to the server, receive data of a second image associated with the identification information of the terminal device or user and the identifier of the marker image from the server, and superimpose the second image over the first image to cause the display to display the second image and the first image while the recording medium is being captured.

Information processing system, terminal device and method of controlling display of secure data using augmented reality

An image forming apparatus includes a conveyance unit configured to convey a recording medium; a reversing unit configured to reverse front and back sides of the recording medium; a recording head configured to reciprocatingly scan to form a first image on a first side of the recording medium, which is reciprocatingly conveyed by the conveyance unit at a first conveyance speed V, and a second image on a second side of the recording medium, which is conveyed at a second conveyance speed Vand ejected, in a case of performing a double-sided printing; and a control unit configured to control the first conveyance speed Vand the second conveyance speed Vto satisfy a relation&#x2266;()&#xd7;2,where t is a scanning time required for one reciprocation of the recording head, and W is an image formation width of the recording head.

Image forming apparatus and image forming method

An ink jet recording apparatus includes: a container to store ink; a detector to detect a remaining ink amount; a liquid feeding unit to supply the ink to the container; an energy generation unit to cause the ink to be discharged; a storage unit to store correspondence information in which driving information for driving the energy generation unit is associated with each piece of time information indicating a supply time taken to supply the ink; and a setting unit to set new driving information using the correspondence information when an actual supply time is different from the supply time indicated by the time information associated with current driving information among the pieces of time information. The actual supply time indicates a time period from when the liquid feeding unit starts supplying the ink until the detector detects that the remaining ink amount is equal to or higher than a threshold.

Ink jet recording apparatus and control method, configured to detect remaining ink

An image forming apparatus includes an image forming device, a conveyance unit, a correction unit, and an attitude controller. The image forming device forms an image on a printing medium. The conveyance unit is disposed opposing the image forming device to convey the printing medium. The correction unit corrects an attitude of a leading edge of the printing medium sent out from the conveyance unit. The attitude controller controls correction of the attitude of the leading edge of the punting medium performed by the correction unit. The attitude controller determines whether or not the correction of the attitude of the leading edge of the printing medium is to be performed, and causes the correction unit to perform the correction when the attitude controller determines that the correction is to be performed.

Image forming apparatus

An image forming apparatus includes a head to eject liquid droplets, a sub-tank having a container to store an amount of liquid supplied to the head, a negative pressure generator unit generating a negative pressure and an air introducing mechanism to introduce air, a main-tank to supply the amount of liquid into the sub-tank, a pressure detector unit to detect a pressure inside the sub-tank, and a controller to control an image forming operation using a remaining amount of liquid in the sub-tank while the main-tank is at an end status, where the controller determines whether the pressure inside the sub-tank is within a normal range, causes, if the detected pressure is not within the normal range, the air introducing mechanism to introduce air to raise the pressure inside the sub-tank, and causes the head to eject non-image forming liquid to cause the pressure to fall within the normal range.

Image forming apparatus and recording medium

A disclosed Web system includes an image forming apparatus; a communication control device connected to the image forming apparatus and including a print server function; and an information processing apparatus connected via a network and the communication control device to the image forming apparatus and configured to obtain information on the image forming apparatus in the form of Web information from the communication control device. The information processing apparatus includes a Web information request unit configured to send an information request to the communication control device to obtain the Web information, the information request including a language identifier. The communication control device includes a Web information storing unit configured to store the Web information, and a Web information returning unit configured to retrieve the Web information corresponding to the language identifier from the Web information storing unit and to send the retrieved Web information to the information processing apparatus.
