Abstract
An image forming apparatus to selectively perform an auto color registration operation, the apparatus including: a printing unit, which forms single-color images, based on printing data, and transfers the images to a printing medium to form a printed image; and a controller which prevents the printing unit from performing the auto color registration operation on the printing data, if the printing data relates a monochromatic printing mode.
Claims19
An image forming apparatus to selectively perform an auto color registration operation, the image forming apparatus comprising:
- a printing unit comprising a plurality of photoconductive media to form a one or more single-color images, a light scanning unit (LSU) to scan light to the photoconductive media, and a conveyer belt to transfer the one or more single-color images on the plurality of photoconductive media to a predetermined location;
- and
- a controller, if print data is received, to control the printing unit to form the one or more single-color images on the plurality of the photoconductive media by controlling a scanning time of the LSU and transfer the one or more single-color images on the conveyer belt,
- wherein the controller determines whether the received printing data is a monochromatic image or a color image, and, if the determined results is monochromatic, controls the printing unit not to perform the auto color registration operation even if a auto color registration condition is satisfied.
A method of controlling an image forming apparatus comprising a printing unit comprising a plurality of photoconductive media to form a one or more single-color images, a light scanning unit (LSU) to scan light to the photoconductive media, and a conveyer belt to transfer one or more single-color images on the plurality of photoconductive media to a predetermined location and a controller, if printing data is received, to control the printing unit to form one or more single-color images on the plurality of photoconductive media by controlling a scanning time of the LSU and transfer the one or more single-color images on the conveyer belt, and selectively performs an auto color registration operation, the method comprising:
- determining whether an auto color registration condition is satisfied;
- receiving printing data;
- determining whether the received printing data is a monochromatic image or a color image;
- and
- if the determined result is monochromatic, controlling the printing unit not to perform the auto color registration operation, even if the auto color registration condition is satisfied.
A method of controlling an image forming apparatus comprising a printing unit comprising a plurality of photoconductive media to form a one or more single-color images, a light scanning unit (LSU) to scan light to the photoconductive media, and a conveyer belt to transfer one or more single-color images on the plurality of photoconductive media to a predetermined location and a controller, if printing data is received, to control the printing unit to form one or more single-color images on the plurality of photoconductive media by controlling a scanning time of the LSU and transfer the one or more single-color images on the conveyer belt, and selectively performs an auto color registration operation, the method comprising:
- determining whether an auto color registration condition is satisfied;
- receiving printing data;
- determining whether the received printing data is a monochromatic image or a color image;
- and
- if the determined result is monochromatic, controlling the printing unit not to perform the auto color registration operation even if the auto color registration condition is satisfied;
- and
- if determined result is color, controlling the printing unit to perform the auto color registration operation,
- wherein the auto color registration condition comprises at least one of,
- a case where fusing temperature to fuse of the image to the printing medium does not correspond to a reference temperature, after power is applied to the image forming apparatus,
- a case where the fusing temperature does not correspond to the reference temperature when the printing unit is in a print-ready state,
- a case where the printing unit has printed more than a predetermined number of sheets of the printing medium,
- a case where a consumable material is replaced, and
- a case where a casing of the image forming apparatus is opened and then closed.
