A print system including a printing apparatus that prints an image on a sheet, a verification apparatus that verifies a sheet printed by the printing apparatus and an information processing apparatus. The information processing apparatus determines whether or not a device having a discharge tray is present between the printing apparatus and the verification apparatus, and in a case where it is determined that the device is present, controls to discharge a sheet printed in a sample printing to the discharge tray when a timing of the sample printing for a user to confirm printing on the sheet is during execution of a print job in which the printing apparatus and the verification apparatus are used.

A processing device including a hardware processor that: determines a dot position at which a dot is to be generated by multiple recording elements arranged in a first direction on a medium which moves relative to the recording elements in a second direction crossing the first direction, based on tone data for each pixel of an image to be formed; determines a corrected dot number that is a number of a dot position by a malfunctioning recording element to which an offset number is added, wherein the malfunctioning recording element is set as a recording element by which a dot is not generated normally among the recording elements; and determines the corrected dot number of a dot position within a dot generation possible range by a recording element other than the malfunctioning recording element.

According to one embodiment, an image forming apparatus includes a driving unit, a first determination unit, a second determination unit, and an output unit. The first determination unit is configured to determine whether or not a rotation abnormality relating to rotation of the driving unit occurs. The second determination unit is configured to determine whether or not a signal abnormality relating to a signal line of a current signal of the driving unit occurs based on a current value of the current signal after the first determination unit determines whether or not the rotation abnormality occurs. The output unit is configured to output a determination result of the second determination unit.

A method of processing linearized and non-linearized Portable Document Format (PDF) files for printing comprises: determining by printer firmware if a printer driver detected that the PDF file is linearized; saving stream data of the PDF file by the printer firmware when the printer firmware determines the printer driver detected that the PDF file is linearized; and determining by the printer firmware if the PDF file is linearized when the PDF file is unidentified as being linearized by the printer driver, wherein the printer firmware identifies real and false linearization error during linearized processing and identifies and processes printing errors in a parallel manner during saving and interpreting stream data.

In a method and device for ascertaining print data for a print image to be printed, the print data is adapted and/or determined such that the time curve of the ink flow quantity, exhibits no quantity changes or flow rates due to which ink ejection errors might be produced, in particular nozzle failures. The device includes: a communication interface configured to receive the print data; and processing circuitry that ascertains, based on the print data, a time curve of an ink flow quantity of ink that, during the printing of the print image, flows in the print bar and/or is ejected from the one or more nozzles of the print bar; and determine, based on the time curve of the ink flow quantity, whether an ink ejection error will be produced.

An image forming apparatus performs a first preparation operation in a full color mode when power is supplied. The apparatus performs, when an image formation request is inputted after the first preparation operation completes, a second preparation operation in a designated color mode in accordance with the image formation request. When an image formation request is inputted during the first preparation operation, the apparatus skips the second preparation operation and performs image formation after the first preparation operation completes.

An information processing apparatus includes circuitry. The circuitry generates an abnormal end file in response to an occurrence of an abnormal end of a process being executed, the abnormal end file indicating an occurrence state of the abnormal end, extracts a part of information from the generated abnormal end file, writes the extracted information as abnormal information in a memory, reads the abnormality information from the memory, and displays the abnormality information on a display.

An information processing method performs steps for an information processing apparatus to communicate with an image forming apparatus having first and second sheet output sections. The second sheet output section can be switched between a close position to serve to guide a sheet to the first sheet output section, and an open position not to guide the sheet to the first sheet output section but to stack the sheet. The method inputs a type of sheet, acquires information indicating whether the second sheet output section is in an open or closed state, and transmits image information to the image forming apparatus. When the sheet type recommends the sheet be output to the second sheet output section and the second sheet output section is in the closed state, a message is output to prompt to switch the second sheet output section into the open position before the image information is transmitted.

A system and method evaluate defects in printed images. A target image, which has been captured of a printed image, is processed to identify defects, where present, which do not occur in a source image from which the printed image was generated. A trained classification model predicts a defect class for respective regions of the target image, each of the defect classes being drawn from a predefined set of defect classes. For at least one of the identified defects, a measure of severity of the defect is determined, such as a size of the defect. A decision on the acceptability of the printed image is made, based on the measure of severity of the at least one defect and the predicted defect class of a respective one of the regions in which the defect occurs.

An image forming system includes an image forming unit configured to form a print image to be printed on a recording medium, based on a raster image and print setting information, a printing unit configured to print an image on the recording medium based on the print image, an image reading unit configured to read the image printed on the recording medium to obtain a read image, and a determination unit configured to determine whether there is an error in the image printed on the recording medium, based on the read image and the raster image. In a case where there is a predetermined difference between the raster image and the read image and the predetermined difference is based on the print setting information, the determination unit does not determine that there is an error in the printed image.
