● This is the processing method when ink stream bending or nozzle clogging is not
repaired even when nozzle backwash was performed.
● Do not perform this work while ink is being ejected. Perform it after setting the IJ
printer to the Stop state.
● Do not touch the ejection port of the nozzle orifice directly with your hand.
(Use the accessory tweezers.)
● If the ejection port of the nozzle orifice is damaged, it may be impossible to
fulfill its function.
