A system and method for automatically scanning a physical document and performing processing actions on the scanned document are provided. The system may include a scanning device that can detect a trigger event when a portable memory device is connected to or paired with the device or when a document, including one or multiple pages, is placed on the document handler of the device. Upon detecting the trigger event, the scanning device may retrieve scan instructions from a designated folder on the portable memory device, automatically scan the document on the document handler, and perform various processing actions on the digital document file for the scanned document based on the scan instructions, with little or no user interaction. The processing actions may include storing, faxing, emailing the scanned document. The instructions for each processing action may be stored at one of multiple designated folders of the portable memory device.

Sheet media jams are detected along a media transport path by one or more vibration sensors that capture mechanical movements of components along the path that interact with the sheet media for driving or guiding the sheet media along the transport path. The detected vibrations during the advancing of the sheets are analyzed for distinguishing between detected vibrations associated with normal handling of the sheets and detected vibrations associated with abnormal handling of the sheets. An error condition can be signaled to a control system in response to distinguishing the detected vibrations associated with the abnormal handling of the sheets.

A method of measuring a display delay time includes a step where a display pattern displayed on a first display including i (i is a natural number greater than 2) display elements is switched to a display pattern other than the display pattern at every elapse of a pattern continuation time, and j (j is a natural number, 1<j<i) display elements brought into a first display state is switched at every elapse, a step where an image of the display pattern on the first display is captured, a step where the captured image is displayed on a second display, and a step where the display delay time from capturing the image on the first display to displaying the image on the second display is measured based on a difference between the display pattern on the first display and the display pattern on the second display.

Systems and methods for identifying the health status of one or more printing devices are provided. An example method can involve determining one or more printing-device error parameters. The method may also involve determining one or more error intervals based on the one or more printing-device error parameters. The method may also involve generating an error frequency code based on the determined error intervals. Still further, the method may involve determining a health value based on the error frequency code. The method yet further includes performing a managing action based on the determined health value.

In a relaying apparatus, a storage stores a plurality of sets of first device information, and second device information assigned to a first set of first device information identifying one image processing apparatus from among image processing apparatuses. The controller communicates with the one image processing apparatus and a service-providing apparatus. The controller receives replacement request information from the one information processing terminal via the communication interface. The replacement request information including old first device information and new first device information. The old first device information indicates the one image processing apparatus. The new first device information indicates another image processing apparatus. The controller replaces the first set of first device information so that the first set of first device information identifies the another image processing apparatus indicated by the new first device information instead of the one image processing apparatus indicated by the old first device information.

An information presentation method includes an apparatus information acquisition step to acquire as apparatus information a detection result of detecting a state of an image forming apparatus by a detection part, an input step to let a user of the image forming apparatus input a content to search for about the image forming apparatus as search input information by an input part, a presentation order determination step to read more than one of multiple answers stored in a server device on a symptom that occurred in the image forming apparatus based on the search input information and the apparatus information, the read answers being to be presented to the user, and to determine a presentation order of the answers, and a presentation step to present, by a presentation part, the answers to the user in the presentation order.

A method of measuring a display delay includes a first step where a first display device performs a switching operation of switching a display pattern displayed on a display unit of the first display device, a second step where a first camera captures a first image and displays the first image in a live view mode, a third step where a second camera captures a second image containing the first image and records at least the first image contained in the captured second image while being correlated with information indicative of an imaging time when the second image is captured, and a fourth step where a display delay time of the first camera from the imaging of the first image to the display of the first image is deduced from the time indicated by the display pattern contained in the first image and the information indicative of the imaging time.

Systems and methods for identifying problematic printers are provided. An example method can involve determining a time interval for a printing device. The method may also involve determining a number of pages printed by the printing device during the time interval. The method may also involve determining a number of printing-device errors that occur on the printing device during the time interval. Still further, the method may involve determining one or more coefficients of a Markov chain based on the number of pages printed by the printing device during the time interval and the number of printing-device errors that occur on the printing device during the time interval. The method yet further includes, based on the determined coefficients of the Markov chain, determining an operational status of the printing device.

An image reading device includes a plate on which a document to be scanned is placed, a cover that is movable between an open position and a closed position at which the cover contacts the document, a position detecting unit configured to detect a position of the cover, an imaging unit configured to emit light towards the plate and having an image sensor configured to detect light reflected by the document, and a control unit configured to determine a size of the document based on a detection result of the position detecting unit and a detection result of the image sensor.

The detected vibrations during the advancing of the sheets are analyzed for distinguishing between detected vibrations associated with normal handling of the sheets and detected vibrations associated with abnormal handling of the sheets.
