A method to determine an operating status of an image forming device comprises: monitoring a plurality of operating parameters of the image forming device during a first time interval; calculating a correlation coefficient during a second time interval between at least two of the plurality of operating parameters; identifying the image forming device as an abnormal operating status when the correlation coefficient calculated during the second time interval is a positive correlation coefficient above a predetermined level associated with a model of the image forming device; and determining a maintenance action for the image forming device based on the abnormal operating status.

Disclosed is an image forming apparatus, including: a job receiver that receives a print job; a printer that executes an image forming in accordance with the print job received by the job receiver; and a hardware processor that: receives an adjustment content and a setting of an execution starting condition of an adjustment for an adjustment item relating to the image forming, and registers the adjustment content and the execution starting condition as a profile; and executes the adjustment in accordance with the adjustment content set in the registered profile when the execution starting condition set in the profile is satisfied.

Example systems and related methods may relate to monitoring performance of an image forming operation. Namely, a system includes an image forming apparatus configured to execute an operation in response to receiving instructions to execute the operation. The system further includes an external sensor circuit that includes one or more sensors and a processor. The one or more sensors are configured to detect a status of an operational parameter of the image forming apparatus indicative of the image forming apparatus executing the operation and receive an instruction to exclude at least a portion of data used to detect the status of the operational parameter. The system further includes a host computing device. The host computing device is configured to generate a plurality of timestamps indicative of when the image forming apparatus executed the operation and a time frame when the external sensor circuit excluded data.

Whenever there happens a change in the state of a device, a host is assured of the current state information of the device. The state information returned from the printer as a response to an inquiry sent from the web print server is stored in a storing unit of the web print server. A result of determination representing whether there happens a change in the state of the printer is stored in the storing unit. The information stored in the storing unit is notified to the tablet as a response to an inquiry sent from the tablet to the web print server. The current state information of the printer is notified to the tablet via the web print server whenever there happens a change in the state of the printer regardless of whether the printer is operated under control of the tablet.

An information processing apparatus includes a processor configured to prohibit, in a case where an opening/closing portion of a target apparatus that generates an operation sound is opened, recording of the operation sound by a microphone provided inside the target apparatus.

The recording device includes an upstream transport roller pair capable of transporting a medium, a recording head configured to record an image by discharging ink at a predetermined timing on the medium transported downstream in a D1 direction by a predetermined transport amount by the upstream transport roller pair while moving in a Y-axis direction intersecting the D1 direction, an image capturing unit configured to read the image recorded on the medium by the recording head, and a control unit, wherein the control unit has a function of performing maintenance for a discharge failure of the ink, a correction of the transport amount, and a correction of the discharge timing of the ink based on the reading result of the image read by the image capturing unit.

An image recording device includes a recorder, a reader and a hardware processor. The recorder records an image on a recording medium. The reader reads, with an imaging element, a surface of the recording medium and a surface of a predetermined reference member. The hardware processor calibrates the reader for a value to be detected by the imaging element, based on a reading result of the reading of the surface of the reference member. Further, the hardware processor performs the calibration in at least one of: a case where a type of the image to be recorded on the recording medium satisfies a predetermined image type condition; and a case where a predetermined reading influence factor which affects a reading result of the reading of the surface of the recording medium satisfies a predetermined reading influence factor condition.

An image reading device includes: light receiving sensors configured to read an image of a document conveyed in a sub-scanning direction and be arranged with an interval in a main scanning direction; one pair of document conveying rollers configured to be provided in front and back of the light receiving sensors in a document conveying direction; a detection unit configured to detect an image overlap amount in an image overlap area and/or an image missing amount in an image missing area; an adjustment amount determination unit configured to determine an adjustment amount for adjusting a distance between the document and the light receiving sensors based on the image overlap amount and/or image missing amount detected; and a drive unit configured to adjust a distance between the document and the light receiving sensors by displacing one of the document conveying rollers and light receiving sensors according to the adjustment amount.

A printing system includes a printer unit configured to print an image on a recording sheet, an inserter configured to insert a sheet into a print product obtained by printing the image on the recording sheet, and one or more controllers having one or more processors and one or more memories. The one or more controllers are configured to generate scanned images by causing the printing system to read the print product and the inserted sheet, register a reference image, inspect the print product based on a scanned image generated by reading the print product and the reference image, set an insertion position of the sheet to be inserted, and perform control so that a scanned image corresponding to the set insertion position of the sheet is not to be inspected.
