Abstract

PURPOSE:To remove nozzle clogging by a method wherein abnormal discharge of ink in a plurality of ink discharging nozzles is detected and purifying liquid is jetted to a group of discharging nozzles showing the abnormal discharge. CONSTITUTION:On a carriage 102, a detecting head 103 and a jet nozzle 104 of purifying liquid are provided. A detection head 103 has a capacity of covering desired number of ink discharging nozzles (e.g.; several tens to several hundreds), detection values relative to the amount of ink reached are converted into current values or voltage values and signals S1 thereto are compared with normal values preset through a controlling circuit 106, in order to detect the abnormal discharge. When the discharge is determined to be abnormal, a signal S2 for operating a pump 107 is outputted and the purifying liquid is discharged from a nozzle 104.
