ELECTROPHOTOGRAPHY; MAGNETOGRAPHY ## Abstract A printing control apparatus includes a conveying unit that conveys a document to a reading unit, a detection unit that detects a size of the document before it begins to be conveyed, a detection unit that detects the size of the document after the document begins to be conveyed, and a control unit that performs a copy job using the reading unit and printing unit based on the size of the document detected before it is conveyed in a case where the printing unit starts to print the image data before the reading unit finishes generating image data for one page and performs a copy job based on the size of the document detected after it begins to be conveyed in a case where the printing unit starts to print the image data after the reading unit finishes generating image data for at least one page. ## Claims ### Claim 1 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 copier comprising: at least one first sensor that detects information regarding the document set on the document setting tray; at least one second sensor that detects, after the conveyor starts to convey the document, information regarding the conveyed document; and a display that displays 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. ### Claim 2 (depends on 1) The copier according to claim 1, wherein the display displays the error information in a case where the first document size determined from the information detected by the at least one first sensor is not same as the second document size determined from the information detected by the at least one second sensor. ### Claim 3 (depends on 1) The copier according to claim 1, wherein the error information is for notifying a user that the document is folded. ### Claim 4 (depends on 1) The copier according to claim 1, wherein the error information is for urging a user to get folds out of the document. ### Claim 5 (depends on 1) The copier according to claim 1, wherein the error information is for urging a user to get folds out of the document. ### Claim 6 (depends on 1) The copier according to claim 1, wherein the display further displays a message for urging a user to set a mixed document sizes mode. ### Claim 7 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. ### Claim 8 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. ### Claim 9 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. ### Claim 10 (depends on 9) The copier according to claim 9, wherein the display displays the error information in a case where the first document size determined based on output from the at least one first sensor is not the second document size determined based on output from the at least one second sensor. ### Claim 11 (depends on 9) The copier according to claim 9, wherein the error information is for notifying a user that the document is folded. ### Claim 12 (depends on 9) The copier according to claim 9, wherein the error information is for urging a user to get folds out of the document. ### Claim 13 (depends on 9) The copier according to claim 9, wherein the error information is for urging a user to get folds out of the document. ### Claim 14 (depends on 9) The copier according to claim 9, wherein the display further displays a message for urging a user to set a mixed document sizes mode. ### Claim 15 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. ### Claim 16 (depends on 15) The copier according to claim 15, wherein the controller interrupts the copy job in a case where the first document size determined based on output from the at least one first sensor is not the second document size determined based on output from the at least one second sensor. ### Claim 17 (depends on 15) The copier according to claim 15, further comprising a display that displays error information based on the first document size determined based on output from the at least one first sensor and the second document size determined based on output from the at least one second sensor. ### Claim 18 (depends on 17) The copier according to claim 17, wherein the error information is for notifying a user that the document is folded. ### Claim 19 (depends on 17) The copier according to claim 17, wherein the error information is for urging a user to get folds out of the document. ### Claim 20 (depends on 17) The copier according to claim 17, wherein the error information is for urging a user to get folds out of the document.
