Description

  The present invention relates to an image forming apparatus, an image forming system, and a recording sheet type selecting method for forming an image based on data input from the outside.

  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 OHP (Overhead projector) sheets made of plain paper, cardboard, or plastic. Appropriate conditions such as the fixing temperature when the image forming apparatus records an image vary depending on the type of the recording sheet. Therefore, the image forming apparatus predetermines image recording conditions for each type of recording sheet, and adjusts the recording conditions according to the type of recording sheet. Also, there are many sizes of recording sheets such as A4 or B5. Usually, the image forming apparatus includes a plurality of trays for storing recording sheets, and the types and sizes of the recording sheets stored in the respective trays are set. When recording an image, the image forming apparatus adjusts the image recording condition according to the type of the recording sheet set for the tray in which the sheet for recording the image is stored.

  In a PC that transmits data to the image forming apparatus, the type of tray and recording sheet for recording images is 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 image recording when the type of the recording sheet designated by the PC is different from the recording sheet set for the designated tray. For this reason, when image recording is stopped, it is necessary to change the type of tray or 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.

The possibility that an image is recorded under appropriate conditions and an image recording failure occurs is reduced. Therefore, the image forming apparatus 1 can improve convenience while suppressing image recording defects.

  In the present embodiment, the image forming apparatus 1 sets the tray according to the size when the data received from the PC 2 includes neither information specifying the tray nor information specifying the type of the recording sheet. It is determined whether the type of the recording sheet matches the type of the recording sheet selected according to the automatic selection setting. If they do not match, the image recording is stopped. There is a possibility that the type of the recording sheet stored in the tray selected according to the size does not match the type of the 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 recording sheet type does not match, it is inappropriate for the recording sheet stored in the selected tray. An image is recorded under the recording conditions, and an image recording failure occurs. Therefore, in the present embodiment, image recording failure is prevented by stopping image recording when the types of recording sheets do not match. Therefore, the image forming apparatus 1 can suppress image recording defects.

  Further, in the present embodiment, the image forming apparatus 1 sets the specified tray when the data received from the PC 2 includes information specifying the tray and information specifying the type of the recording sheet. By default, the determination of comparing the type of the recording sheet with the type of the designated recording sheet is not executed. For this reason, the image forming apparatus 1 normally does not stop the image recording, and the convenience is improved. When the recording sheet types are set to be compared, the image forming apparatus 1 prevents image recording failure by stopping image recording when the recording sheet types do not match. In this case, since the image recording is stopped in a state where the user specifies the tray and the recording sheet type, the user is inadequately specifying the type of the tray or the recording sheet. It can be assumed that it was. Even if the image recording is stopped, the countermeasure is easy to understand, so that a decrease in convenience is suppressed.
