Image forming apparatus, method for controlling image forming apparatus, image processing system, and storage medium

An image processing system comprising:

• an image forming apparatus;
• and
• an information processing apparatus,
• wherein the image forming apparatus includes
• a printer that prints a predetermined pattern image on a sheet,
• a first controller that provides a notification of an orientation for placing, on a placement portion, the sheet on which the predetermined pattern image is printed by the printer,
• a scanner that scans, on a line to line basis, the image formed on the sheet on which the predetermined pattern image is printed and which is placed on the placement portion, to generate image data, and
• a network interface that transmits the image data generated by scanning the sheet by the scanner, to the information processing apparatus,
• wherein the information processing apparatus includes a second controller that detects a streak-shaped image extending in a direction along a predetermined edge of the sheet, by analyzing the image data received from the image forming apparatus, and
• wherein the first controller provides a notification of a placement orientation for allowing the scanner to scan, on a line to line basis, the sheet on which the predetermined pattern image is formed, the line extending in a direction along the predetermined edge.

A method for controlling an image processing apparatus, the control method comprising:

• printing, by a printer a predetermined pattern image on a sheet;
• providing, by a controller, a notification of an orientation for placing, on a placement portion, the sheet on which the predetermined pattern image is printed in the printing step;
• scanning, by a scanner and on a line to line basis, the sheet on which the predetermined pattern image is printed and which is placed on the placement portion to generate image data;
• and
• detecting, by the controller, a streak-shaped image extending in a direction along a predetermined edge of the sheet, by analyzing the image data generated by scanning the sheet in the scanning step,
• wherein, in the providing step, a notification of a placement orientation for allowing the sheet, on which the predetermined pattern image is printed, to be read on a line to line basis, the line extending in a direction along the predetermined edge, is provided by the controller.

A non-transitory computer readable storage medium storing a program for executing a control method for controlling an image processing apparatus, the control method comprising:

• printing, by a printer, a predetermined pattern image on a sheet;
• providing, by a controller, a notification of an orientation for placing, on a placement portion, the sheet on which the predetermined pattern image is printed in the printing step;
• cading scanning, by a scanner and on a line to line basis, the sheet on which the predetermined pattern image is printed and which is placed on the placement portion to generate image data;
• and
• detecting, by the controller, a streak-shaped image extending in a direction along a predetermined edge of the sheet, by analyzing the image data generated by scanning the sheet in the scanning step,
• wherein, in the providing step, a notification of a placement orientation for allowing the sheet, on which the predetermined pattern image is printed, to be read on a line to line basis, the line extending in a direction along the predetermined edge, is provided by the controller.
