Description

  The present invention relates to an image forming apparatus that forms an image based on externally input data, an image forming system, and a recording sheet type selection method.

  Data is transmitted from an information processing apparatus such as a PC (personal computer) to an image forming apparatus, and the image forming apparatus records an image based on the data on a recording sheet. There are many types of recording sheets, such as an OHP (Overhead projector) sheet made of plain paper, cardboard, or plastic. Appropriate conditions such as the fixing temperature when the image forming apparatus records an image differ depending on the type of recording sheet. Therefore, the image forming apparatus determines in advance the image recording conditions for each type of recording sheet, and adjusts the recording conditions according to the type of recording sheet. Further, the recording sheet has many sizes such as A4 or B5. Usually, the image forming apparatus includes a plurality of trays for storing recording sheets, and sets the type and size of the recording sheets stored in each tray. When recording an image, the image forming apparatus adjusts the recording condition of the image according to the type of recording sheet set for the tray in which the sheet for recording the image is stored.

  In a PC that transmits data to an image forming apparatus, a tray for recording an image and a type of a recording sheet are designated. The image forming apparatus records an image on a recording sheet stored in a designated tray. At this time, the image forming apparatus stops the recording of the image when the type of the recording sheet specified by the PC is different from the recording sheet set for the specified tray. Therefore, when the recording of the image is stopped, it is necessary to change the type of the tray or the recording sheet designated by the PC. Patent Document 1 discloses a technique for outputting an error when the type of recording sheet set in the image forming apparatus is different from the type of recording sheet specified by the PC.

When the type of the tray or the recording sheet is not specified by the user's operation, the data transmitted by the PC 2 does not include information for specifying the type of the tray or the recording sheet.

  FIG. 6 and FIG. 7 are flowcharts illustrating the procedure of the process executed by the image forming apparatus 1 according to the first embodiment. The control unit 11 waits for reception of data including image data transmitted from the PC 2 by the communication unit 17 as needed (S101). If no data has been received (S101: NO), the control unit 11 continues to wait for data reception. When data is received by the communication unit 17 (S101: YES), the control unit 11 determines whether or not the received data includes information designating the type of the recording sheet (S102). If the data does not include information specifying the type of recording sheet (S102: NO), the control unit 11 determines whether the received data includes information specifying a tray (S103). . If the data includes information specifying a tray (S103: YES), the control unit 11 stores a recording sheet for recording an image from the plurality of paper feed trays 44 and the manual feed tray 45. The tray specified by the information included in the data is selected as the tray (S104).

  Next, the control unit 11 determines whether or not the type of recording sheet for the selected tray is set in the tray setting stored in the setting storage unit 14 (S105). When the type of the recording sheet is set for the selected tray (S105: YES), the control unit 11 determines the type of the recording sheet on which the image is to be recorded in the tray setting for the selected tray. The type is selected (S106). If the type of recording sheet is not set for the selected tray (S105: NO), the control unit 11 selects the type of recording sheet set to the default setting as the type of recording sheet for recording an image.

After S109 ends, the image forming apparatus 1 ends the processing.

When the data does not include the information designating the tray in S103 (S103: NO), the control unit 11 sets the recording specified by the information included in the data as the tray storing the recording sheet for recording the image. A tray is selected according to the sheet size (S110). In S110, the control unit 11 refers to the tray setting stored in the setting storage unit 14 and selects a tray for which the same size as the recording sheet specified by the information included in the data is set in the tray setting. I do. In S110, the control unit 11 may select a tray according to the size of the image represented by the image data included in the received data. Next, the control unit 11 selects the type of recording sheet specified in the automatic selection setting stored in the setting storage unit 14 as the type of recording sheet on which an image is to be recorded (S111). Next, the control unit 11 determines whether or not the type of the recording sheet set in the tray setting for the selected tray matches the type of the recording sheet selected in S111 (S112). When the types of the recording sheets match (S112: YES), the control unit 11 advances the processing to S108. If the types of the recording sheets do not match (S112: NO), the control unit 11 displays an error on the display unit 13 (
S113), recording of the image is stopped.

  If the data includes the information specifying the type of the recording sheet in S102 (S102: YES), the control unit 11 determines whether the received data includes the information specifying the tray (S102). S21). If the data includes the information specifying the tray (S21: YES), the control unit 11 sets the tray specified by the information included in the data as the tray storing the recording sheet for recording the image. Is selected (S22). Next, the control unit 11 selects the type of the recording sheet specified by the information included in the data as the type of the recording sheet on which the image is to be recorded (S23). Next, the control unit 11 refers to the determination setting stored in the setting storage unit 14 and sets the determination to compare the type of the selected recording sheet with the type of the recording sheet set in the tray setting. It is determined whether or not it is set (S24). If it is not set to make a determination to compare the types of recording sheets (S24: NO), the control unit 11 advances the processing to S108.

  If the data does not include the information designating the tray in S21 (S21: NO), the control unit 11 sets the recording specified by the information included in the data as the tray storing the recording sheet for recording the image. A tray is selected according to the sheet size (S25). In S25, the control unit 11 may select a tray according to the size of the image represented by the image data included in the received data. Next, the control unit 11 selects the type of the recording sheet specified by the information included in the data as the type of the recording sheet on which the image is to be recorded (S26). If it is set to make a determination to compare the types of recording sheets in S24 (S24: YES), or after S26 ends, the control unit 11 sets the recording sheets set in the tray setting for the selected tray. It is determined whether or not the type of the print sheet matches the type of the selected recording sheet (S27). If the types of the recording sheets match (S27: YES), the control unit 11 advances the processing to S108. If the types of the recording sheets do not match (S27: NO), the control unit 11 displays an error on the display unit 13 (S28) and stops recording the image.

  As described above in detail, in the present embodiment, the image forming apparatus 1 is configured such that the data received from the PC 2 includes the information specifying the tray and does not include the information specifying the type of the recording sheet. Then, instead of selecting the type of recording sheet selected in the automatic selection setting, the type of recording sheet set for the specified tray is selected, and an image is recorded. In this case, the image forming apparatus 1 does not stop recording the image. For this reason, even if the data includes information for specifying the tray and does not include the information for specifying the type of the recording sheet, the image recording is stopped compared to the conventional image forming apparatus in which the recording of the image is sometimes stopped. Thus, the convenience of the image forming apparatus 1 is improved. In addition, the type of recording sheet set for each tray in the image forming apparatus 1 is likely to match the type of recording sheet actually stored in the image forming apparatus 1, so that the type of recording sheet is not An image is recorded under appropriate conditions, and the possibility of image recording failure occurring is reduced. Therefore, the image forming apparatus 1 can improve convenience while suppressing image recording failure.

Further, in the present embodiment, if the information received from the PC 2 does not include the information specifying the tray and the information specifying the type of the recording sheet, the image forming apparatus 1 sets the tray according to the size. It is determined whether or not the type of the recording sheet that has been set matches the type of the recording sheet selected in accordance with the automatic selection setting. If not, the image recording is stopped. There is a possibility that the type of recording sheet stored in the tray selected according to the size does not match the type of recording sheet set in the automatic selection setting. Since the image recording conditions are adjusted according to the type of recording sheet selected according to the automatic selection setting, if the types of recording sheets do not match, an inappropriate recording sheet stored in the selected tray An image is recorded under recording conditions, and image recording failure occurs. Thus, in the present embodiment, image recording is stopped when the types of recording sheets do not match, thereby preventing image recording failure. Therefore, the image forming apparatus 1 can suppress the image recording failure.

  Further, in the present embodiment, when the information received from the PC 2 includes the information for specifying the tray and the information for specifying the type of the recording sheet, the image forming apparatus 1 sets the specified tray. By default, the determination of comparing the type of a given recording sheet with the type of the designated recording sheet is not performed. For this reason, usually, the image forming apparatus 1 does not stop recording an image, and the convenience is improved.
