Abstract
An image forming apparatus includes a maximum document number decision part that decides a number of media that are carried simultaneously on a medium carrying path at the time of double sided printing, a memory part that stores image data of a document, a print data editing part that generates page data to be printed on the media from the image data in the memory part, a print page generation monitoring part that monitors a page data number generated by the print data editing part, a print start timing decision part that decides a print start timing from the number of media and the page data number, a print mechanism controller that starts printing based on the print start timing determined by the print start timing decision part.
Claims6
An image forming apparatus, comprising:
- a reading mechanism that includes a document reading part that reads an image of a document;
- a print mechanism that includes an image forming part that forms the image on a print medium and that is capable of performing double sided printing to form images on front and back sides of the print medium in a first double sided print mode and a second double sided print mode in which a distance between print media is set shorter than the first double sided print mode;
- a maximum print medium number decision part that decides a number of pages of the print media that are carried simultaneously on a medium carrying path of the print mechanism at a time of the double sided printing;
- a memory part that stores image data of the document read by the document reading part;
- a print data editing part that generates print data to be printed on the print media from the image data stored in the memory part;
- a print page generation monitoring part that monitors a page count of the print data generated by the print data editing part;
- a print start timing decision part that decides print start timing for printing a page of the print data that is to be printed first based on the number of pages of the print media decided by the maximum print medium number decision part and the page count of the print data monitored by the print page generation monitoring part;
- and
- a print mechanism controller that starts printing of the print data based on the print start timing determined by the print start timing decision part, wherein
- the print start timing decision part increments a double sided print page count for each two page counts of the print data generated by the print data editing part, and
- the print start timing decision part decides that it has reached the print start timing for the print data when the number of pages of the print media decided by the maximum print medium number decision part becomes less than the incremented double sided print page count.
An image forming apparatus that is capable of performing double sided printing on print media, comprising:
- a generation part that generates print data from received data;
- a monitoring part that monitors a page count of the print data generated by the generation part;
- a decision part that decides print start timing for printing a page of the print data that is to be printed first based on a number of pages of the print media that can be simultaneously carried inside the image forming apparatus and the page count of the print data;
- and
- a print part that starts the double sided printing of the print data based on the print start timing decided by the decision part, wherein
- the decision part decides that it has reached the print start timing and instructs the print part to start the double sided printing of the print data when M≦N/2 is satisfied, where the number M is the number of pages of the print media that can be simultaneously carried inside the image forming apparatus, and the number N is the page count of the print data.
