A media transport system is used to transport a media sheet along a media transport path past an image capture system. The image capture system includes an image capture device positioned to capture an image of the media sheet, and a platen positioned behind the media sheet, wherein a surface of the platen includes a non-uniform density pattern. The image capture system captures an image of the media sheet that includes at least one edge of the media sheet and a portion of the platen that extends beyond the edge of the media sheet. An image analysis system automatically analyzes the captured digital image to detect an edge position of the media sheet by detecting a platen region that includes the non-uniform density pattern and a media region. The detected edge position is used to adjust a position that a printing module prints image data onto the media sheet.

An image forming apparatus includes an image forming unit, an intermediate transfer member, a power source, and a control unit configured to perform a mode to output a test chart which is formed by transferring a plurality of test toner images from the intermediate transfer member to a plurality of sheets of the recording material. In a case where a jam occurred during execution of the mode, the control unit is configured to resume the mode after the jam has been recovered. In a case where the control unit resumes the mode after the jam has occurred during the execution of the mode, the control unit is configured to resume the mode from a first sheet of the plurality of sheets of the recording material regardless of a number of sheets of the recording material not discharged due to the jam.

An image forming apparatus configured to form an image on a sheet includes an apparatus body, a drawer unit configured to be pulled out from the apparatus body, a cover provided to be openable and closable on the apparatus body, the cover being movable to a closed position where the cover covers the drawer unit attached to the apparatus body and an open position where the drawer unit is exposed so as to be pulled out from the apparatus body, a restricting portion configured to transit to a restricted state in which the drawer unit is restricted from being pulled out from the apparatus body and an allowable state in which the drawer unit is allowed to be pulled out from the apparatus body, and a display portion provided in the drawer unit and configured to display a state of the restricting portion.

A card processing device may include a print unit and a card inverting unit that inverts front/rear of the card. The print unit may include a thermal head and a card conveyance mechanism. The card inverting unit may include a card holding part, a card drawing and feeding mechanism, and a rotating mechanism that rotates the card holding part. A conveyance path may be provided inside the card holding part. The conveyance path may be linear. The card drawing and feeding mechanism may include two drive rollers, and two pad rollers. A distance between a center of the drive roller and a center of the thermal head may be shorter than a length of the card. The thermal head may print on the card while the card conveyance mechanism conveys the card. The rotating mechanism may rotate the card holding part such that the conveyance path is inclined.

An image forming apparatus includes an image forming portion, a pair of conveyance rollers, a conveyance member, and a cleaning unit. The image forming portion forms an image on a sheet. The pair of conveyance rollers conveys the sheet at a predetermined timing to an image formation position at which the image is formed by the image forming portion. The conveyance member conveys the sheet at the image formation position. The cleaning unit includes a cleaning member that is configured to come in contact with a target roller and the conveyance member, the target roller being one of the pair of conveyance rollers that comes in contact with the sheet.

An image forming apparatus includes a first fixing member, a second fixing member, a heater, a switching mechanism capable of switching a nip state of the first fixing member and the second fixing member between (i) a first nip state in which the belt is nipped between each of the first nip forming member and the second nip forming member, and the first fixing member, and (ii) a second nip state in which the belt is nipped between the first nip forming member and the first fixing member in a state in which the belt is not nipped between the second nip forming member and the first fixing member, and a controller configured to switch the nip state from the first nip state to the second nip state when a jam error occurs in the first nip state.

An image forming apparatus includes a casing having a front end and a rear end, a first tray, a first print engine, a second tray, a second print engine and a controller. The controller configured to perform: receiving first image data representing the first image and second image data representing the second image; executing a first process including a first conveying process and a first recording process; executing a second process including a second conveying process and a second recording process; determining whether an error has occurred in the second process; and in a case where the error has occurred in the second process, stopping the second process while continuing the first process.

An image forming system includes an image forming apparatus and a sheet laminator. The image forming apparatus forms an image on a sheet being conveyed as an inner sheet. The sheet laminator performs a sheet laminating operation on a two-ply sheet in which the sheet conveyed from the image forming apparatus is inserted between two sheets of the two-ply sheet. The sheet laminator includes a heater and circuitry. The heater heats the two-ply sheet during the sheet laminating operation. The circuitry is to execute a control mode when a specific abnormal event occurs among a plurality of abnormal events that occurs in the image forming apparatus, where the control mode maintains heating by the heater of the sheet laminator for a predetermined time and interrupt the heating by the heater when an abnormal event other than the specific abnormal event occurs.

An image forming apparatus includes a plurality of light emitting portions configured to expose to light a photosensitive drum, a detection unit configured to detect an opening of a maintenance door, a output unit configured to output image data for controlling turning on and off of the plurality of light emitting portions, a drive unit configured to drive the plurality of the light emitting portions based on the image data, wherein the photosensitive drum stops rotating when the detection unit detects that the maintenance door is open, wherein the output unit output the image data indicating turning off of the plurality of light emitting portions when the detection unit detects that the maintenance door is open, and a power supplied to the drive unit is maintained in a case where the maintenance door is opened.

With stoppage of recording material feeding including a first belt and a second belt (YES in S1), a controller causes cooling operation for the recording material by a cooling fan and a belt fan to continue without stop (S4). By continuing the cooling operation of a recording material cooling device, even if the recording material stagnates in the recording material cooling device in a state of being nipped by the first belt and the second belt, the temperature of the recording material can be lowered. Then, the toner on the recording material is cooled, the toner on the recording material is unlikely to adhere to the first belt or to the second belt.
