Abstract

PURPOSE:To prevent nozzle clogging and inaccurate printing by driving a nozzle irrelevant to recording based on the results of a means of counting the idle time of the nozzle provided on an ink jet recorder. CONSTITUTION:An ink jet recorder, especially an ondemand type ink jet recorder, is provided with a means of counting the idle time of a nozzle. Based on the results of counting the time, an ink is recorvered or discharged irrelevant to the printing content from several dots to scores of dots so that ink drops can be discharged in a heightened viscosity. Then, discharge of ink is performed for printing.
