A printing device is provided comprising a camera to capture an image of at least a portion of a print substrate; a controller to determine a location of a portion of a side edge of the substrate from the image to determine a distance of the print substrate from a predetermined location; and adjustment apparatus to adjust the entire substrate laterally, relative to the direction of transport of the substrate, based on the determined location.

An example of apparatus to align media. The apparatus includes a printer assembly to form markings a first side of a media. The apparatus also includes a sensor to detect a backside pattern on each pass at multiple locations. The apparatus includes a processor in communication with the sensor. The processor is to compare the backside pattern measured on multiple passes to determine offset amounts. The apparatus also includes a controller to adjust the media relative to the printer assembly based on the offset values.

An image processing device includes: a fold unit that folds a first adjustment sheet including an adjustment pattern, over the adjustment pattern based on a predetermined reference fold position; an image reader that reads an image of the adjustment pattern with the first adjustment sheet folded by the fold unit unfolded; a position identifying unit that, based on a fold line in the image of the adjustment pattern read by the image reader, identifies a position of the fold line; and a position adjusting unit that adjusts a fold position of the fold unit based on a difference between the position of the fold line identified by the position identifying unit and the reference fold position. The image reader includes a scanner that scans the first adjustment sheet relatively in a direction along fold of the first adjustment sheet, and reads the image of the adjustment pattern.

An image forming apparatus includes an image forming unit to form an image on a sheet conveyed from a sheet storing unit by a sheet conveying unit, and a registering unit that registers detected sheet thickness information and detected sheet surface characteristics information. Based on information, distinct front and back surfaces of a conveyed predetermined sheet and a type of the conveyed predetermined sheet is determined. If the predetermined sheet type matches a type of an upcoming sheet on which the image will be formed and the determined front and back surfaces matches front and back surfaces of the upcoming sheet, an image is formed on the predetermined sheet. If the predetermined sheet type matches the upcoming sheet type and the determined front and back surfaces do not match the upcoming sheet front and back surfaces, information is displayed conveying that the predetermined sheet front and back surfaces are inverted.

Provided are an image forming apparatus, a method of controlling sheet insertion and a non-transitory computer-readable recording medium. The image forming apparatus includes a print engine, an image checker, a sheet inserter, a sheet ejector and one or more controllers. When the image checker receives a media sheet output from the print engine, the one or more controllers perform a check whether an image formed on the media sheet is defective or not, by using measured image obtained by a sensor of the image checker. The one or more controllers further cause a sheet inserter to start putting an insertion sheet into the sheet path, after a determination that an image of one of media sheets output from the print engine is non-defective is made, as a result of the check.
