A print apparatus is disclosed. In some examples, the print apparatus comprises a print head to deposit print agent onto a substrate; a detector to detect a fiducial; a first light source to back-illuminate the substrate, such that light from the first light source is to be detected by the detector through the substrate; and processing apparatus. The processing apparatus is to operate the print head to deposit print agent to form a first fiducial on a first side of the substrate, the first fiducial comprising a shape of a first colour and having a first dimension, and a background of print agent of a second, different colour, wherein the first dimension of the shape does not exceed a corresponding dimension of the background; operate the print head to deposit print agent to form a second fiducial on a second, opposite side of the substrate, the second fiducial comprising an inverted version of the shape of the first colour; operate the first light source to back-illuminate the substrate; operate the detector to detect the first and second fiducials; and determine whether the first fiducial is aligned with the second fiducial. A method and a machine-readable medium are also disclosed.

Generally, a job management apparatus of the present embodiment which sends a print job to an image forming apparatus comprises a communication section and a controller. The communication section communicates with the image forming apparatus and a delivery apparatus configured to deliver a sheet printed by the image forming apparatus to a delivery destination. The controller calculates printing time relating to completion of execution of the print job by the image forming apparatus and first arrival time when the delivery apparatus reaches the image forming apparatus and enables the image forming apparatus to execute the print job at a timing when the image forming apparatus can complete the execution of the print job by the first arrival time.

An inspection apparatus includes: a hardware processor that: conducts an inspection on an image by comparing a scanned image with a correct image, the image being formed on paper in accordance with a print job, the scanned image being generated by reading the image, the correct image serving as a reference for the inspection of the image; and determines whether a page is a target for the inspection in accordance with a type of the paper on which the image will be formed according to print setting of the print job, wherein the hardware processor conducts the inspection on the image on a page that has been determined to be the target for the inspection by the hardware processor, and does not conduct the inspection on the image on a page that has been determined to not be the target for the inspection.

A method for printing defect detection includes processing and analyzing a difference image obtained by comparing an image scanned with a verifier to a reference image. The detected defects are grouped, and the grouping is refined. Confidence level values are then assigned to the refined groups, and analysis is performed to determine if one or more servicing actions should be taken.

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 Dl 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 forming apparatus comprising: an image forming unit configured to convey a recording medium, and form an image on the recording medium based on an image forming condition; and a controller configured to control the image forming unit to form a test image and a scale image extending a conveyance direction in which the recording medium is conveyed, obtain user instruction information related to a density fluctuation of the test image in the conveyance direction, and to generate the image forming condition to suppresses image density unevenness in the conveyance direction to an image to be formed by the image forming unit based on the user instruction information.

A printer, capable of appropriately extending an existing replacement recommendation time of a component determined based on a life prescribed for the component, includes: a time determination unit (timer), a comparison examination unit (comparator), and a notification unit (notifier). The timer determines a time at which replacement of a component is recommended based on tendency information indicating a deterioration tendency of the component with respect to an operation status. The tendency information is generated from collection and storage of information on the operation status collected from a plurality of printers and information on a degree of deterioration at a disposal time of the component. The comparator compares a time output by the time determination unit with a predetermined life of the component, and examines whether to perform recommendation for component replacement. The notifier notifies of information on recommendation for component replacement based on an examination result of the comparator.

An image processing apparatus includes an acquisition unit configured to acquire first image data indicating a reference image as a target print result, and second image data indicating a target image to be inspected, and a processing unit configured to inspect the target image by performing a correction on a second partial region adjacent to a first partial region to enhance the second partial region relative to a difference image representing a difference between the reference image and the target image based on the first image data and the second image data, the first partial region having a difference in between the reference image and the target image.

An image forming apparatus includes an image forming unit to form an image on a sheet, a conveyance unit to convey the sheet having the image formed thereon to a conveyance path and a reading unit to read a test image of a sheet conveyed to the conveyance path. In addition, a controller determines an adjustment value for adjusting a geometric characteristic of an image to be formed by the image forming unit based on a reading result of the reading unit, controls the image forming unit to form the test image, controls the reading unit to read the sheet having the test image formed thereon, and determines an adjustment value for adjusting a geometric characteristic of an image to be formed by the image forming unit based on a reading result of the reading unit.

Embodiments of the present disclosure provide an image calibration method, an image forming apparatus, and a storage medium. The method includes outputting a calibration image in response to a calibration instruction, where the calibration image includes a calibration pattern and a calibration mark; according to the calibration mark of the calibration image, determining whether a calibration event corresponding to the calibration image matches a calibration event corresponding to a current calibration operation, or determining whether a calibration event type corresponding to the calibration image matches a calibration event type corresponding to a current calibration operation; and performing image calibration according to the calibration pattern in the calibration image if the calibration event corresponding to the calibration image matches the calibration event corresponding to the current calibration operation, or if the calibration event type corresponding to the calibration image matches the calibration event type corresponding to the current calibration operation.
