Printing control apparatus method for controlling printing control apparatus and storage medium

A method for controlling a copier comprising a conveyor for conveying a document set on a document setting tray, a reader which is able to read an image on the document conveyed by the conveyor to generate image data, and a printer for printing the image based on the image data, the method comprising:

• detecting, by at least one first sensor, information regarding the document set on the document setting tray;
• and
• detecting, by at least one second sensor after the conveyor starts to convey the document, information regarding the conveyed document;
• and
• displaying error information based on a first document size determined from the information detected by the at least one first sensor and a second document size determined from the information detected by the at least one second sensor.

A non-transitory computer readable storage medium for storing a computer program for controlling a copier comprising a conveyor for conveying a document set on a document setting tray, a reader which is able to read an image on the document conveyed by the conveyor to generate image data, and a printer for printing the image based on the image data, the computer program comprising:

• a code to detect, by at least one first sensor, information regarding the document set on the document setting tray;
• and
• a code to detect, by at least one second sensor after the conveyor starts to convey the document, information regarding the conveyed document;
• and
• a code to cause a display to display error information based on a first document size determined from the information detected by the at least one first sensor and a second document size determined from the information detected by the at least one second sensor.

A copier comprising a conveyor for conveying, via a conveying path, a document set on a document setting tray, a reader which is able to read an image on the document conveyed by the conveyor to generate image data, and a printer for printing the image based on the image data, the copier comprising:

• at least one first sensor on the document setting tray;
• at least one second sensor in the conveying path;
• and
• a display that displays error information based on a first document size determined based on output from the at least one first sensor and a second document size determined based on output from the at least one second sensor.

A copier comprising a conveyor for conveying, via a conveying path, a document set on a document setting tray, a reader which is able to read an image on the document conveyed by the conveyor to generate image data, and a printer for printing the image based on the image data, wherein the copier performs a copy job using the reader and the printer, the copier comprising:

• at least one first sensor on the document setting tray;
• at least one second sensor in the conveying path;
• and
• a controller that interrupts the copy job based on a first document size determined based on output from the at least one first sensor and a second document size determined based on output from the at least one second sensor.
