Patent ID: 7311369

Claim:
An apparatus that corrects a white line of an ink-jet printer, comprising: a driving section which rotates one or more rollers to transfer a paper and drives an ink cartridge in response to control signals, so that the printing is implemented in a preset printing width; a memory which stores information relating to an overfeeding amount and an overfeeding position of the corresponding paper according to a type of the paper; and a control section which outputs the control signals to the driving section so that the paper is sequentially fed according to the preset printing width, wherein the control section calls the information relating to the overfeeding amount and the overfeeding position stored in the memory, judges the corresponding overfeeding amount and overfeeding position according to the type of the paper, and outputs control signals if the control section judges that the printing position is located on the line positioned just before the overfeeding position, so that the printing is implemented by dummy nozzles corresponding to the overfeeding amount together with nozzles corresponding to the entire preset printing width, thereby forming an overfeeding printing area that is greater than a normal printing area printed by the nozzles alone.
