An image forming apparatus including a plurality of processing units capable of performing different support processing for a user asking for support, and a remote support apparatus operated by an operator are connected via a communication path. The remote support apparatus transmits to the image forming apparatus a request to perform the support using the selected processing unit, or a request to switch the processing unit to a selected specific processing unit and a request to perform the support. The image forming apparatus allows the processing unit which follows the request to perform the support, to perform the support, and switches the processing unit according to the request to switch the processing unit to allow the switched processing unit to perform the support. Further, the image forming apparatus returns a result which should be returned, among results of the performed support, to the remote support apparatus.

An image reading device includes an image processor that generates correction data to be used for shading correction and perform the shading correction using the correction data, and a memory that stores first black correction data to be used for the shading correction in a main scanning direction in a predetermined first position in a predetermined sub-scanning direction. The image processor generates third black data based on an image signal of a second reference plate extending in the sub-scanning direction in a predetermined second position in the main scanning direction, generates black correction data according to the sub-scanning direction based on the first black correction data and the third black data, and performs the shading correction using the black correction data so as to correct density unevenness in the main scanning direction and the sub-scanning direction caused by an interference between image signals from a plurality of sensors.

An image reading device has an image processor that generates correction data to be used for shading correction and performs the shading correction using the correction data. The image processor generates intermediate data with a predetermined density level, generates intermediate data in different positions in the sub-scanning direction based on image signals of a first reference plate and a second reference plate disposed in the different positions, generates first and second black correction data based on the respective intermediate data, generates black correction data according to the sub-scanning direction based on both the black correction data, and performs the shading correction using the black correction data in the respective positions in the sub-scanning direction.

A method of measuring a display delay time includes a step where a display pattern displayed on a first display including i (i is a natural number greater than 2) display elements is switched to a display pattern other than the display pattern at every elapse of a pattern continuation time, and j (j is a natural number, 1<j<i) display elements brought into a first display state is switched at every elapse, a step where an image of the display pattern on the first display is captured, a step where the captured image is displayed on a second display, and a step where the display delay time from capturing the image on the first display to displaying the image on the second display is measured based on a difference between the display pattern on the first display and the display pattern on the second display.

An image reading apparatus includes: a sensor module which includes a light source and sensors; a reference member for creating black correction data and white correction data; and an image processor. The image processor corrects uneven density of an image resulting from interference of image signals from the sensors, by performing, on the image signals obtained by the sensors, shading correction using black correction data and white correction data. The image processor obtains causes the sensors to obtain image signals of the reference member, and creates the white correction data based on white data, and the black correction data based on intermediate data. At least one of when creating the white correction data and when creating the black correction data, the image processor causes the sensors to obtain image signals of the reference member a plurality of times.

When trial printing is executed in a repeat printing mode, trial printing is performed in size of an image of one piece in a layout in which a plurality of images are supposed to be printed in the repeat printing mode normally. A user who has checked a finished state of the trial printing sets, when the finished state is in a desired state, the recording paper on which the trial printing is performed to the paper feed portion again and executes the repeat printing. Thereby, in a blank space excluding a print image which is printed with a first time trial printing, a scheduled quantity of a plurality of images are repeatedly printed.
