A printing system includes a printing unit configured to print an image on a sheet, a receiving unit configured to receive an adjustment value from a user, first and second adjustment units, and a control unit. The first adjustment unit conveys the sheet on which the image is printed by the printing unit to a reading apparatus, and performs a first adjustment based on an image read by the reading apparatus. The second adjustment unit performs a second adjustment based on the adjustment value received by the receiving unit. The control unit prevents the first adjustment from being performed for a sheet of a size where the first adjustment is not properly performed among sheets for the printing unit to print an image on. The control unit does not prevent the second adjustment from being performed for the sheet of the size where the first adjustment is not properly performed.

Provided is a method of operating an image forming apparatus. The method includes: calculating a remaining lifespan of at least one component consumed through an image forming job in the image forming apparatus; determining whether to proceed with a refill operation to refill a toner in a cartridge of the image forming apparatus, based on the remaining lifespan of the at least one component; and displaying guide information to guide the refill operation based on a result of the determining.

A printing system includes an information processing apparatus including first circuitry and an image forming apparatus. The first circuitry is configured to receive designation of superimposing an image of a particular color on a print target image, associate the image of the particular color with the print target image in response to a reception of the designation of superimposing, and transmit print data including the print target image and the image of the particular color to the image forming apparatus. The image forming apparatus includes second circuitry configured to receive the print data and interpret the print data, and a printer engine configured to superimpose the image of the particular color on the print target image in printing, according to interpretation of the print data.

An image forming apparatus includes a processor. The processor is configured to stop a print job under execution in response to an occurrence of an abnormality preventing the print job from continuing, set the stopped print job to a skip state, and restart the print job set to the skip state in response to a restart instruction by a user associated with the print job and not by a second user different from the user associated with the print job.

An abnormal state detection device includes: an acquisition unit that acquires an image imaging a device that outputs an abnormal state using an LED; an analysis unit that analyzes the abnormal state of the device based on the light emission pattern of the LED in the image, and generates auxiliary information indicating the abnormal state based on the analysis result; and a display control unit that outputs the auxiliary information to a display unit.

A sheet accommodating apparatus includes an apparatus body, a first cassette to be drawn out in a draw-out direction with respect to the apparatus body, a second cassette disposed adjacent to the first cassette in a vertical direction, a holder member attached to the apparatus body, and a first light emitting member and a second light emitting member that are supported by the holder member. The first cassette includes a first accommodating container and a first cover. The second cassette includes a second accommodating container and a second cover. The first cover has a first hole in a position opposing the first light emitting member such that the light emitted from the first light emitting member passes therethrough. The second cover has a second hole provided in a position opposing the second light emitting member such that the light emitted from the second light emitting member passes therethrough.

In an image forming apparatus, a controller performs processes in accordance with an operation mode settable to one of a first subscription mode and a second subscription mode. The first subscription mode corresponds to a first subscription in which a specific-color cartridge is a subscription subject and a non-specific-color cartridge is not the subscription subject. The second subscription mode corresponds to a second subscription in which both the specific-color cartridge and the non-specific-color cartridge are the subscription subject. The controller performs restricting usage of the non-specific-color cartridge in a case where the first subscription mode is set as the operation mode and the type information of the non-specific-color cartridge indicates the subscription type, compared to a case where the second subscription mode is set as the operation mode and the type information of the non-specific-color cartridge indicates the subscription type.

An image forming apparatus includes an upper guide unit fixed to the image forming apparatus and configured to guide an upper surface of the sheet discharged by a roller pair, a stack unit provided at a position recessed from an upper exterior unit of the image forming apparatus, and an operation unit including a display unit. The discharged sheets are stacked on the stack unit. The upper guide unit extends more to a downstream side in the discharge direction than the roller pair. The operation unit and the upper guide unit each have a portion overlapping with each other. When viewed in an axial direction of the roller pair, the operation unit and the upper guide unit are arranged at positions through which a straight line orthogonal to a plane passing through axes of rollers of the roller pair and passing through a nip portion of the roller pair passes.

A printing apparatus connectable to an inspection apparatus in a communicable manner according to the present invention includes a reception unit configured to receive an inspection job including at least information indicating whether a correct answer image is to be registered, an analysis unit configured to analyze the received inspection job, and, a control unit configured to perform control so that the correct answer image is transmitted to the inspection apparatus in a case where the correct answer image is to be registered, and to perform control so that an instruction to select the correct answer image is transmitted to the inspection apparatus in a case where the correct answer image is not to be registered, as a result of the analysis.

An iconographic control panel of an image forming apparatus is provided. The iconographic control panel includes a plurality of physical iconographic control buttons respectively corresponding to a plurality of functions of the image forming apparatus, each of the plurality of physical iconographic control buttons comprising at least one dedicated light emitting diode, and at least one processor to determine an availability of the plurality of functions of the image forming apparatus respectively corresponding to each of the plurality of physical iconographic control buttons, determine a functional state of the plurality of functions of the image forming apparatus determined to be available, and control an illumination of the at least one LED of each of the plurality of physical iconographic control buttons based on the availability of each function corresponding to each of the plurality of physical iconographic control buttons and the functional state of each function determined to be available.
