Abstract
A duplex recording method for an image forming apparatus stores page-by-page image data in a storage in the order of page and records, among the image data, two consecutive pages of image data on the front and rear of a recording medium, respectively. At this instant, the method records the image data on the rear of the recording medium carrying an image on the front and a new recording medium alternately by using an interleaf control system. Assume that images are continuously recorded on the fronts of n consecutive recording media at the initial stage of printing. Then, the method continuously records images on the fronts of n+1 consecutive recording media at the final stage of printing. An apparatus for practicing the method is also disclosed.
Claims29
In a method of recording, among image data stored in an order of page, two consecutive pages of image data on a first and a second side of a recording medium, respectively, by interleaf control that records image data alternately on said second side of said recording medium carrying an image on said first side and a new recording medium, assuming that the image data are continuously recorded on first sides of n consecutive recording media at the beginning, said interleaf control continuously prints the image data on first sides of n+1 consecutive recording media at a final stage of printing.
In a method of recording, among image data stored in an order of page, two consecutive pages of image data on a first and a second side of a recording medium, respectively, by interleaf control that records image data alternately on said second side of said recording medium carrying an image on said first side and a new recording medium, assuming that the image data are continuously recorded on first sides of n consecutive recording media at the beginning, said interleaf control continuously prints the image data on first sides of maximum 2n −1 consecutive recording media at a final stage of printing.
A duplex image recording apparatus for recording images on a first and a second side of a recording medium by interleaf control that records images alternately on said second side of said recording medium carrying an image on said first side and a new recording medium, said duplex image recording apparatus comprising:
- storing means for storing image data in an order of page;
- recording means for recording, among the image data stored in said storing means, two consecutive pages of image data on a first and a second side of a recording medium, respectively;
- reversing means for reversing, after the image data has been recorded on the first side of the recording medium, said recording medium;
- conveying means for again conveying the recording medium reversed by said reversing means toward said recording means to thereby allow the image data to be recorded on the second side of said recording medium;
- and
- control means for controlling said storing means, said recording means, said reversing means, and said conveying means;
- said control means causing, assuming that the image data are continuously printed on first sides of n consecutive recording media at the beginning, the image data to be printed on first sides of n+1 consecutive recording media at a final stage of printing.
