  FIG. 4 is a flowchart illustrating an example of printing processing of a received facsimile image after the end of facsimile reception in the image processing apparatus 100 illustrated in FIG.

  In FIG. 4, when facsimile reception is completed, first, it is checked whether double-sided printing is set with reference to double-sided / single-sided printing setting information stored in the auxiliary storage unit 3 (step 401).

  If it is determined in step 401 that double-sided printing is set (YES in step 401), then whether the back paper is set in all the paper feed trays, that is, stored in the auxiliary storage unit 3. For example, it is checked whether all the tray information is set on the backing paper as shown in FIG. 2B (step 402).

  If it is determined that no backing paper is set in all the paper feeding trays (NO in step 402), there is a paper feeding tray in which no backing paper is set. A paper feed tray having a sheet size suitable for the received image is selected from among the paper feed trays that are not present with reference to the tray information stored in the auxiliary storage unit 3, and the image output unit 8 is selected on both sides of the received image. Is printed (step 403), whereby the duplex printing of the received image by the image output unit 8 is started.

  If it is determined in step 401 that double-sided printing is not set (NO in step 401), or if it is determined in step 402 that the back paper is set in all the paper feed trays (step If YES in 402), a paper feed tray having a paper size suitable for the received image is selected from all the paper feed trays with reference to the tray information stored in the auxiliary storage unit 3, and the image output unit 8 is selected. A command is given to print the received image on one side (step 404), whereby the one-sided printing of the received image by the image output unit 8 is started.

  According to such a configuration, even when double-sided printing is set and the back paper is set in all the paper feed trays, the received image can be printed out by single-sided printing.

  Also, if there is a paper feed tray that is set for duplex printing and no backing paper is set, the paper feeding tray that does not have this backing paper selected is used for duplex printing. It is possible to eliminate the inconvenience of printing again on the printed recording surface.

  FIG. 5 is a flowchart illustrating another example of the printing process of the received facsimile image after the end of the facsimile reception in the image processing apparatus 100 shown in FIG.

  The printing process shown in FIG. 5 also shows the printing process of the received facsimile image after the end of the facsimile reception in the image processing apparatus 100 shown in FIG. 1, but in the flowchart of FIG. 5, as shown in FIG. This shows a case where a paper feed tray used for printing a received facsimile image is set in advance corresponding to the line.

  That is, in FIG. 6, “paper feed tray 1” is set for “line 1” connected to the communication control unit 6 shown in FIG. 1, and “paper feed tray” is set for “line 2”. 2 ”is set, and this information is stored in the auxiliary storage unit 3 as line-corresponding tray information.

  In FIG. 5, when the facsimile reception is completed, first, the line tray corresponding to the line corresponding to the line shown in FIG. Select (step 601).

  Next, it is checked whether the back paper is set in the selected paper feed tray (step 602).

  If it is determined that no backing paper is set in the selected paper feed tray (NO in step 602), it is further checked whether double-sided printing is set (step 603).

  If it is determined in step 603 that double-sided printing is set (step 603 YES), printing on both sides is instructed using the paper feed tray selected in step 601 (step 604). The duplex printing of the received image by the output unit 8 is started.

  If it is determined in step 602 that the back paper is set in the selected paper feed tray (YES in step 602), or if it is determined in step 603 that duplex printing is not set ( (NO in step 603) instructs printing on one side using the paper feed tray selected in step 601 (step 605), thereby starting single-sided printing of the received image by the image output unit 8.

  According to such a configuration, even if the back paper is set in the paper feed tray used for printing the line that received the facsimile image and the double-sided printing is set, the back paper is already printed on the recording surface. The inconvenience of printing again can be solved.

  FIG. 7 is a flowchart showing still another example of printing processing of a received facsimile image after the end of facsimile reception in the image processing apparatus 100 shown in FIG.

  The printing process shown in FIG. 7 also shows the printing process of the received facsimile image after the facsimile reception is completed in the image processing apparatus 100 shown in FIG. 1, but in the flowchart of FIG. The case where there is a notification of a manuscript is shown.

  In this case, if there is a tray with no backing paper set in the paper feed tray, the paper tray with the paper size that matches the received image is selected from the paper trays that have no backing paper set. Select to perform duplex printing, but if the back paper is set in all the paper feed trays, the paper size that matches the received image in all paper feed trays is notified despite the notification of double-sided documents. Select a paper tray and perform single-sided printing.

  That is, in FIG. 7, when the facsimile reception is completed, it is first checked whether there is a double-sided document notification from the partner side during the facsimile reception (step 701).

  If it is determined in step 701 that there is a notification of a double-sided document (YES in step 701), then, referring to the tray information stored in the auxiliary storage unit 3, back paper is placed in all the paper feed trays. It is checked whether it is set (step 702).

  Here, if it is determined that no backing paper is set in all the paper feeding trays (NO in step 702), paper feeding of a paper size suitable for the received image is made in a paper feeding tray in which no backing paper is set. A tray is selected by referring to the tray information stored in the auxiliary storage unit 3, and the image output unit 8 is instructed to print the received image on both sides (step 703). 8 starts double-sided printing of the received image.

  If it is determined in step 701 that there is no notification of a double-sided document (NO in step 701), or if it is determined in step 702 that the back paper is set in all the paper feed trays (step 702). YES) selects a paper feed tray having a paper size suitable for the received image from all of the paper feed trays with reference to the tray information stored in the auxiliary storage unit 3, and selects the paper output tray for the image output unit 8. Printing of the received image on one side is instructed (step 704), whereby the image output unit 8 starts to print the received image on one side.

  According to such a configuration, even if there is a notification of a double-sided document from the other side and the back paper is set in all the paper feed trays, the received image can be printed out by single-sided printing.

  Also, if there is a double-sided document notification from the other party and there is a paper feed tray that does not have a backing paper set, the paper feeding tray that does not have this backing paper selected will be used for duplex printing. It is possible to eliminate the inconvenience of printing again on the already printed recording surface of the backing paper.

  FIG. 8 is a flowchart showing still another example of printing processing of a received facsimile image after the end of facsimile reception in the image processing apparatus 100 shown in FIG.

  The print processing shown in FIG. 8 also shows the print processing of the received facsimile image after the end of facsimile reception in the image processing apparatus 100 shown in FIG. 1, but in the flowchart of FIG. 8, as shown in FIG. The case where it is set is shown.

  That is, FIG. 9 shows a case where the paper sizes usable for facsimile reception are designated as A4 and B5, and this information is stored in the auxiliary storage unit 3 as facsimile reception paper information.

  In FIG. 8, when facsimile reception is completed, it is first checked whether double-sided printing is set with reference to double-sided / single-sided printing setting information stored in the auxiliary storage unit 3 (step 801).

  If it is determined that double-sided printing is set (TES in step 801), all the specified sheet sizes are supplied with reference to the facsimile reception sheet information stored in the auxiliary storage unit 3. It is checked by referring to the tray information stored in the auxiliary storage unit 3 whether or not the backing paper is set in the paper tray (step 802).

  If it is determined in step 802 that no backing paper is set in all the paper feeding trays (NO in step 802), a paper feeding tray that does not have a backing paper set with a paper size that matches the received image is selected. Then, a double-sided printing instruction is issued (step 803), whereby double-sided printing of the received image by the image output unit 8 is started.

  If it is determined in step 801 that double-sided printing is not set (NO in step 801), or it is determined in step 802 that the back paper is set in all the paper feed trays of the specified paper size. If yes (YES in step 802), the tray information stored in the auxiliary storage unit 3 is referred to and it is checked whether there are a plurality of paper feed trays having a paper size suitable for the received image (step 804).

  If it is determined that there are a plurality of paper feed trays having a paper size suitable for the received image (YES in step 804), then it is checked whether there is a paper feed tray set with the back paper (step 805). If there is a paper feed tray with a backing paper set (YES in step 805), the paper feeding tray with the backing paper set is selected and a single-sided printing instruction is issued (step 806), thereby outputting an image. Single-sided printing of the received image by the unit 8 is started.

  If it is determined in step 805 that there is no paper feed tray set with backing paper (NO in step 805), an arbitrary paper feed tray is selected and a single-sided printing instruction is issued (step 807). The single-sided printing of the received image by the image output unit 8 is started.

  If it is determined in step 804 that there are not a plurality of paper feed trays having a paper size suitable for the received image (NO in step 804), a paper tray having a paper size suitable for the received image is selected and a single-sided printing instruction is issued. This is done (step 808), whereby the single-sided printing of the received image by the image output unit 8 is started.

  According to such a configuration, even when double-sided printing is set and the back paper is set for all the paper feed trays of the specified paper size, the received image can be printed out by single-sided printing.

  In addition, when duplex printing is set and there are multiple paper feed trays with a paper size that matches the received image, printing is performed preferentially from the paper feed tray with the back paper set, so the back paper can be used effectively. It becomes possible.

  FIG. 10 is a flowchart showing an example of processing at the start of facsimile reception in the image processing apparatus 100 shown in FIG.

  The processing shown in FIG. 10 is configured so that the reception paper size is declared to the other party at the start of facsimile reception in consideration of the case where there is a paper feed tray with a backing paper set.

  That is, in FIG. 10, when facsimile reception is started, first, it is checked whether the back paper is set in all the paper feed trays with reference to the tray information stored in the auxiliary storage unit 3 (step 1001). .

  If it is determined that no backing paper is set in all the paper feed trays (NO in step 1001), double-sided printing is performed with reference to the double-sided / single-sided printing setting information stored in the auxiliary storage unit 3. Is set (step 1002).

  If it is determined in step 1002 that double-sided printing is set (YES in step 1002), the paper size of the paper feed tray with no backing paper set is declared as the received paper size (step 1003), and the facsimile is set. Continue receiving.

  If it is determined in step 1001 that the back paper is set in all the paper feed trays (YES in step 1001), or if it is determined in step 1002 that duplex printing is set (in step 1002). NO) declares the paper size of all paper feed trays as the received paper size (step 1004), and continues facsimile reception.

  According to such a configuration, if there is a paper feed tray with no backing paper set and duplex printing is set, declare the paper size of the paper tray without the backing paper as the receiving paper size. Therefore, it is possible to eliminate the inconvenience that the received image is printed again on the recording surface on which the back paper is already printed, and the size of the received paper even when the back paper is set in all paper feed trays. This makes it possible to control the printing of received images using the backing paper effectively.

  In the above-described embodiment, the case where the single-sided printing paper is a backing paper whose one side is already used for printing has been described. Can be applied to.

  The present invention can be used for an image processing apparatus such as a facsimile machine, a printer, and a copying machine. According to the present invention, when double-sided printing is set and single-sided printing paper suitable for printing on only one side such as a backing paper is set in the paper feed tray, the double-sided printing setting is ignored. Single-sided printing, so even if single-sided printing paper is stored in the paper feed tray, it may be printed again on the recording surface that has already been printed, or printed on a printing surface that is not suitable for printing. In addition, it is possible to effectively use single-sided printing paper such as a backing paper.
