Printing method and image forming apparatus for performing the same

Abstract

In an image forming apparatus using an engine part which is capable of moving in the width direction of paper fed in the print direction, a printing method has the steps of measuring a position in the width direction of paper fed in the print position, comparing measured position value with a preset reference position value, compensating a position to be printed based on the compared difference, and printing on the paper based on the compensated position data.

Description

technical field [0001] The present invention relates to a printing method of an image forming apparatus. More particularly, the present invention relates to a printing method of an image forming apparatus that compensates for a positional error of paper for normal printing. Background technique [0002] Generally, an image forming apparatus such as an ink jet printer uses a pickup roller to pick up and supply sheets one by one from a sheet feeding member. The paper is arranged in a certain printing position by the pickup roller. Features such as feed position and speed are sensed by sensors such as feed sensors and controlled by the control unit based on the sensed information so that the entire sheet can be printed. [0003] If the paper is in the printing position, the carrier reciprocates along the width direction of the paper perpendicular to the feeding direction, and the ink is ejected from the ink head at the lower part of the carrier to print along the width direct...

Problems solved by technology

[0005] However, the paper may not be fed properly but skewed to one side

Specifically, when feeding B5 paper smaller than A4 paper, B5 paper is set in the printer driver, but the paper may be skewed to one side, and thus may not be fed to coincide with the printing start and end points of the printing area of ​​B5 paper
