Abstract
An image forming apparatus is provided including at least one color cartridge that supplies at least one color toner, a monochrome cartridge that supplies monochrome toner, an image formation unit configured to form an image on an image-transferring member using at least one of the at least one color toner and the monochrome toner, and a processor electrically coupled to the image formation unit. The processor is configured to determine whether the at least one color cartridge contains insufficient color toner for printing an image according to a first image job and to control the image formation unit to print a second image job before the first image job requiring the at least one color cartridge if the at least one color cartridge contains insufficient color toner for printing the image of the first image job.
Claims13
An image forming apparatus comprising:
- at least one color cartridge that supplies at least one color toner;
- a monochrome cartridge that supplies monochrome toner;
- an image formation unit configured to form an image on an image-transferring member using at least one of the at least one color toner and the monochrome toner;
- and
- a processor electrically coupled to the image formation unit, the processor configured to:
- determine whether the at least one color cartridge contains insufficient color toner for printing an image according to a first image job;
- and
- control the image formation unit to print a second image job before the first image job requiring the at least one color cartridge if the at least one color cartridge contains insufficient color toner for printing the image of the first image job,
- wherein the second image job is a monochrome image job and the first image job is a color image job;
- wherein, when the processor determines that the at least one color cartridge contains insufficient color toner for printing an image according to the first image job, the processor controls, without any user input, the image formation unit to print the second image job and a third image job that is a monochrome image job before the first image job.
An image forming apparatus comprising:
- at least one color cartridge that supplies at least one color toner;
- a monochrome cartridge that supplies monochrome toner;
- an image formation unit configured to form an image on an image-transferring member using at least one of the at least one color toner and the monochrome toner;
- and
- a processor electrically coupled to the image formation unit, the processor configured to:
- determine whether the at least one color cartridge contains insufficient color toner for printing an image according to a first image job;
- and
- control the image formation unit to print a second image job before the first image job requiring the at least one color cartridge if the at least one color cartridge contains insufficient color toner for printing the image of the first image job,
- wherein the second image job is a monochrome image job and the first image job is a color image job;
- wherein, when the processor determines that the at least one color cartridge contains insufficient color toner for printing an image according to the first image job, the processor controls, without any user input, the image formation unit to print all pending monochrome image jobs before the first image job.
A method of forming images on an image-transferring member, comprising:
- providing at least one color cartridge that supplies at least one color toner;
- providing at least one monochrome cartridge that supplies monochrome toner;
- determining whether the at least one color cartridge contains insufficient color toner for printing an image according to a first image job;
- printing a second image job before the first image job requiring the at least one color cartridge if the at least one color cartridge contains insufficient color toner for printing the image of the first job,
- wherein the second image job and a third image job are monochrome image jobs and the first image job is a color image job, and the second and third image jobs are printed ahead of the first image job without any user input.
An image forming apparatus comprising:
- at least one color cartridge means that supplies at least one color toner;
- a monochrome cartridge means that supplies monochrome toner;
- an image forming means for forming an image on an image-transferring member using at least one of the at least one color toner and the monochrome toner;
- and
- a processing means electrically coupled to the image forming means, for determining whether the at least one color cartridge means contains insufficient color toner for printing an image according to a first image job, and for controlling the image forming means to print a second image job before the first image job requiring the at least one color cartridge means if the at least one color cartridge means contains insufficient color toner for printing the image of the first image job,
- wherein the processing means controls, without any user input, the image forming means to print monochrome image jobs before color image jobs when the processing means determines that at least one color cartridge means contains insufficient color toner for printing the image according to the first image job.
