6-11 ●How to correct ink stream bending and nozzle clogging
6.4.2 Nozzle orifice disassembly and cleaning
● 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.
Handle the nozzle orifice carefully so that the ejection port is not damaged by the tool.
Remove and clean the nozzle orifice.
(a) Loosen the fixing screw and remove the charge electrode and deflection electrode.
To prevent dropping, do not remove the screw.

(d) Place the removed nozzle orifice into a beaker containing makeup and clean the orifice.
(b) Remove the four screws holding the nozzle orifice.
(c) Use the tweezers to remove the nozzle orifice from the nozzle body.
The O-ring may detach from the nozzle orifice at this time. If it does, put the O-ring in a
beaker with makeup ink and take care not to lose it.
