A method of producing a machine learning model includes collecting, as training data, data including an image of a document and a size of the document or a size of an actually copied output sheet from a copying apparatus that copies the document on the output sheet, and producing a model for determining whether or not a mark included in the image of the document is identifiable by a user on the document or the copied output sheet based on the training data.

A configurable document server is described. In some embodiments, the configurable document server can enable administrators to set an option that prevents documents from being routed to users when the configurable document server experiences some types of errors. When the configurable document server determines that such an error condition exists, it may prevent the routing of the corresponding document. By preventing documents causing errors from being routed, the configurable document server enables administrators to improve the accuracy of document workflow and thereby improve productivity of users.

There is provided a controller configured to execute: obtaining of color values of picture elements, respectively, of P pieces of target picture element columns; identifying of a blank picture element, indicating a white color as a brightest color; and identifying a candidate picture element line as a blank line which is a picture element line indicating the white color as the brightest color, the candidate picture element line being constructed of T pieces of picture elements arranged side by side in a second direction and including the P pieces of target picture elements located at a same position in the first direction, in a case that the candidate picture element line satisfies a first blank line condition, wherein the P is a integer in a range of not less than 2 to less than the T.

An image forming apparatus including applications and system side software for providing system side services to the applications is provided, in which the image forming apparatus includes: an authentication module for displaying an authentication screen on an operation panel of the image forming apparatus, wherein the authentication module allows the image forming apparatus to display a screen for using the image forming apparatus instead of the authentication screen if authentication data input from the authentication screen satisfies an authentication condition, and wherein the authentication module is provided in the image forming apparatus separately from the system side software.

A configurable document server is described. In some embodiments, the configurable document server can enable administrators to set an option that prevents documents from being routed to users when the configurable document server experiences some types of errors. When the configurable document server determines that such an error condition exists, it may prevent the routing of the corresponding document. By preventing documents causing errors from being routed, the configurable document server enables administrators to improve the accuracy of document workflow and thereby improve productivity of users.

Techniques describe opportunistically capturing and tagging images with wireless information by a mobile device. The tagged image may be transmitted to a remote server, such as a crowdsourcing server, where the location at which the image was captured may be determined using visual features from the image. An association between the location and the wireless measurements may be used in building/maintaining a heatmap. In one embodiment, techniques are described for setting camera parameters for opportunistically capturing images and may include receiving at least one signal associated with at least one signal emitting device, determining information associated with the at least one signal emitting device using the at least one signal, setting at least one camera parameter for a camera coupled to the mobile device based on the information associated with the at least one signal emitting device, and capturing one or more images using the at least one camera parameter.

A job processing apparatus that is capable of positively stopping a transmission job desired by a user. A transmission job is input according to a user's operation. Uncompleted transmission jobs out of input transmission jobs are managed by a job management table. A first stop instruction for stopping a transmission job is received according to a user's operation. In a case where the first stop instruction is received during display of a configuration screen for making settings of a transmission job, a transmission job input last out of the transmission jobs managed by the job management table is searched for, and the searched-for transmission job is stopped.

In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.

An image forming apparatus includes a sensor, an operation section, and a controller. The sensor detects a sensor target. The operation section receives an operation instruction. The controller executes a setting process for controlling the sensor. The setting process is a process to adjust a sensitivity of the sensor according to detection precision. The detection precision is a relationship in a first unit period between the number of times the sensor detects the sensor target and the number of times of the operation section receives the operation instruction.

An image processing apparatus includes the following. A communicator performs data communication with a terminal apparatus. A hardware processor provides through the communicator to the terminal apparatus screen information to form a display screen displayed on a display of the image processing apparatus, and displays the display screen with a browser of the terminal apparatus. The screen information includes the following. Functional information shows a function included in the image processing apparatus. An information analysis program allows a computer of the terminal apparatus to function as a functional information extractor which extracts functional information of the image processing apparatus from the screen information, a functional difference specifier which specifies the functional difference between the image processing apparatus and another image processing apparatus based on the functional information, and a display controller which controls the display to display the functional difference on the display screen.
