Image forming apparatus, image forming method, and image forming management apparatus

An image forming apparatus comprising:

• an image forming unit that forms an image on a transfer medium on the basis of image data;
• a feeder that feeds the transfer medium;
• and
• a control unit that manages image data and controls the image forming unit and the feeder,
• wherein the control unit is configured to associate two print jobs selected by an operator, set one of the print jobs with a first print data as a base image, and set the other of the two print jobs with a second print data as an overprint image,
• wherein, in a case where the base image is to be first printed on a first side of the transfer medium by the image forming apparatus, the transfer medium with the base image is to be placed back into the feeder, and the overprint image is to be applied on the first side of the transfer medium to the base image by the image forming apparatus, when a jam of the transfer medium is detected during an output of the overprint image the control unit causes a transfer medium to which the base image is output by the image forming apparatus to be replenished for print in place of a jammed transfer medium removed by jam processing, and
• wherein the control unit causes the transfer medium to which the base image is output to be replenished by one of:
• (i) causing blank replacement transfer medium in an amount of transfer medium removed during jam processing to be inserted in the feeder, the base image to be reprinted on the blank replacement transfer medium, and the replacement transfer medium with the reprinted base image to be returned to the feeder before restarting printing of the overprint images after the jam processing;
• or
• (ii) causing printing of the overprint images to be restarted until a paper empty condition occurs in the feeder, blank replacement transfer medium to be inserted in the feeder, the base image to be printed on the blank replacement transfer medium, and the overprint image to be printed on the replacement transfer medium with the base image.
