Abstract
An ink jet printer has an ink jet printing head with a plurality of nozzles, an ink jet compensation controlling device for driving the ink jet printing head, and a detecting device for detecting a status of the nozzles. When the detecting device detects at least one malfunctioning nozzle, the ink jet compensation controlling device selects a group of normal nozzles according to the position of the malfunctioning nozzle and controls the group of normal nozzles to form corresponding printing strips on the document. The printing strips formed by the normal nozzles cover an area of the printing strips normally formed by the malfunctioning nozzle.
