Image forming apparatus and image forming method

Abstract

The present invention relates to an image forming apparatus and an image forming method. The image forming apparatus continuously performs primary paper feeding, which transports paper from the paper feed roller to the registration position roller, and secondary paper feeding, without stopping the registration roller, and secondary paper feeding, which transfers the paper from the opposite roller. The bit position roller is transported to the output roller. The image forming apparatus divides the document data into zone data and stores them, calculates the specific zone number corresponding to the preceding paper feeding timing corresponding to the paper size and paper orientation, and completes the image processing up to the specific zone number, Outputs the advance paper feed timing notification. According to the present invention, paper can be fed at the most appropriate timing.

Description

technical field [0001] The present invention relates to an image forming apparatus and an image forming method that discharge paper from a paper feed tray at an appropriate timing. Background technique [0002] A typical image forming apparatus such as a printer and a multifunction peripheral (MFP) first executes an action of outputting paper from a paper feed tray after receiving a print request. That is, the image of the original is duly transferred to the paper by outputting the paper from the paper feed tray before the image formation of the original read by the scanner is completed. For example, there is an image forming apparatus that predicts image forming time by calculating the command size of an intermediate language of image data, thereby transferring an image to paper in a timely manner. By predicting the image forming time, the time when the paper reaches the position to be transferred and the time when the image transfer can be started are adjusted, thereby im...

Problems solved by technology

However, the mechanism for stopping the sheet using the registration rollers complicates the structure and control of the image forming apparatus, resulting in high cost of the image forming apparatus.

In an image forming apparatus in which the registration roller motor is omitted and the paper does not stop at the registration roller position even if there is a roller at the registration roller position, it is difficult to adjust the time when the paper reaches the transferred position and when the image transfer can be started. printed moment
