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 device includes: an image forming unit that forms an image on a transfer medium; and a controller that controls multiple image readers capable of performing image reading for the same surface of the transfer medium, and acquires reading results from the image readers. The controller is capable of performing failure/no-failure determination for the image on the transfer medium based on the reading results, of switching image reading by the multiple image readers between reading by a first number of image readers and reading by a second number of image readers, the second number being smaller than the first number, and of enabling, while the second number of image readers perform reading, at least one of the other image readers to execute a maintenance operation for the at least one of the other image readers.

A reading device and an image forming apparatus are provided. The reading device includes an image reading device configured to read an image on a recording medium being conveyed, a background device serving as a background image when the image is read by the image reading device, and a foreign-object detector configured to compare a first read image obtained as the background device is read by the image reading device with a second read image obtained as the background device and the recording medium are read by the image reading device to detect an attached foreign object. The image forming apparatus includes the reading device and an image forming device.

A method for reducing artifacts in an electrophotographic printing system includes receiving a print job including image data for a set of pages. The electrophotographic printing system is used to print a block of pages from the print job to provide corresponding printed pages. The image data for the block of pages is analyzed to determine an average toner usage rate. If the determined average toner usage rate for the block of pages falls outside an acceptable toner usage rate range, image data for a compensation image and a number of compensation images are determined such that the average toner usage rate will be brought back into the acceptable toner usage rate range.

An image forming apparatus prints an image on a sheet. The image forming apparatus includes a casing, a plurality of open/close devices, a plurality of fans, and a control device. The casing includes a plurality of openings and a plurality of ventilation holes. The plurality of open/close devices are attached to the casing, and configured to open and close the respectively corresponding openings. The plurality of fans each generate an airflow from inside of the casing to a corresponding one of the plurality of ventilation holes. The control device controls operation of the plurality of fans. The control device also detects occurrence of an event that restricts execution of the printing, identifies a type of the event, selects at least one of the plurality of fans according to the type of the event, and drives the selected fan.

A reading device includes: plural transport rolls that transport a document along a transport path, include a discharge roll disposed on a most downstream side of the transport path, and rotate and do not rotate in synchronization with one another; an opening and closing unit that exposes or covers an upstream portion of the transport path; plural detectors that are provided apart from one another along the transport path, detect a transported document, and include a discharge detector that is disposed on a most downstream side of the transport path and is disposed on an upstream side relative to the discharge roll in a document transport direction; a reader that reads an image formed on a transported document in a downstream portion of the transport path; and a controller that stops the plural transport rolls once upon occurrence of a document jam inside a device body by controlling the transport rolls and rotates the transport rolls for only a predetermined period in a case where the discharge detector is detecting no document and a length of a document is equal to or longer than a threshold length.

An image forming system includes an image forming unit, an inspection unit, a conveyance unit configured to convey a sheet to the inspection unit, a controller configured to execute a first inspection mode in which a sheet having an image formed thereon is conveyed by the conveyance unit to the inspection unit and is inspected, and a second inspection mode in which, without executing image forming by the image forming unit, a sheet is conveyed by the conveyance unit to the inspection unit and is inspected, and a setting unit configured to set a recovery process. The setting unit permits the setting of the recovery process in the first inspection mode and prohibits the setting of the recovery process in the second inspection mode.

An image forming device includes: an image forming unit that forms an image on a transfer medium; and a controller that controls multiple image readers capable of performing image reading for the same surface of the transfer medium, and acquires reading results from the image readers. The controller is capable of performing failure/no-failure determination for the image on the transfer medium based on the reading results, of switching image reading by the multiple image readers between reading by a first number of image readers and reading by a second number of image readers, the second number being smaller than the first number, and of enabling, while the second number of image readers perform reading, at least one of the other image readers to execute a maintenance operation for the at least one of the other image readers.

This disclosure provides an image processing apparatus that is connected to a printing apparatus, sequentially receives a plurality of recording media on which printing was performed by the printing apparatus, and inspects a quality of images formed on the recording media, wherein the image processing apparatus receives a reference image, acquires a plurality of scanned images by sequentially scanning the recording media output from the printing apparatus and having the images to be inspected recorded thereon, receives phase information of an image bearing member of the printing apparatus, detects, for each of the scanned images, a defect on the scanned image by comparing a pixel value of the reference image and a pixel value of the scanned image, and determines whether a defect has reproducibility based on positions of defects on the recording media calculated from the phase information.

An operation mode setting apparatus includes: a log information acquiring section which acquires log information of a target device capable of switching a normal mode operation that is performable in a normal mode and a maintenance mode operation that is performable in a maintenance mode; an operation history information acquiring section which acquires maintenance mode operation history information indicating an operation history of the target device in the maintenance mode; a specific operation extracting section which extracts a maintenance mode operation which is to be performed in the maintenance mode under a specific condition in the log information as a specific operation based on the log information acquired by the log information acquiring section and the maintenance mode operation history information acquired by the operation history information acquiring section; and an operation mode changing section which changes the specific operation from a maintenance mode operation to a normal mode operation.
