INK JET PRINTER CAPABLE OF PERFORMING BORDERLESS PRINTING WORK

摘要

PURPOSE: An ink jet printer is provided to perform borderless printing work by detecting the size of a printing paper using a sensor capable of detecting an alignment of the printing paper without conveying the printing paper. CONSTITUTION: An ink jet printer includes a paper feeding section(110), a recording head(120) running in a main scanning direction, a paper conveying section(130) for conveying a paper, and a support member(140) for supporting a paper conveyed in a sub-scanning direction from a lower portion of the recording head(120). The recording head(120) is mounted on a carriage(160). An exhaust section is formed in front of the support member(140). The carriage(160) is slidably coupled with a guide shaft(180). A nozzle section having a plurality of exhaust ports are formed at a lower portion of the recording head(120).
