Abstract

A printing head including a nozzle unit having a length corresponding to a width of a paper and prints an image on the paper by projecting ink onto the paper while staying stationary. The nozzle unit is divided into a plurality of nozzle sections. A plurality of cap members is provided with each cap member corresponding to at least one nozzle section. A cap drive unit moves the plurality of cap members between a a capped position and an uncapped position. A motor drives the cap drive unit.

Description

technical field [0001] The invention relates to an ink jet printer. Specifically, the present invention relates to an inkjet printer provided with a print head having a nozzle consistent with the width of the printing paper. [0002] This application claims Korean Application No. filed on July 1, 2004. Priority of 10-2004-0051010, the entire contents of which are hereby incorporated by reference. Background technique [0003] In general, an inkjet printer is a device that forms an image on paper by spraying ink from a print head onto the upper surface of the paper. The print head is usually spaced a desired distance from the upper surface of the paper, and reciprocates in a direction perpendicular to the direction in which the paper is fed. The print head includes a nozzle unit having a plurality of nozzles. If the nozzle unit is exposed to the air for a long time, the ink will dry out and clog the nozzles. Also, dust in the air will adhere to the nozzle and block it. ...
