I How to restore a dry pen
Water-based fiber-tip pens:
Remove the pen and try writing with it on a piece of paper. If the ink flow is not restored, moisten the pen's tip
with water and shake the pen up and down, etc.
Disposable, refillable ink pens and high-speed ceramic pens
NOTE
Do not attempt to disassemble the tip of refillable ink pens. The tip of disposable ink pens cannot be re-
moved.
(1) To restore the flow of ink, remove the pen and try writing with it on a piece of paper.
(2) If Step (1) is not effective, try the methods below.
(a) With the pen's tip facing upward, tap the pen gently several times on a hard surface as shown below,
then try writing with the pen. Repeat this several times until the ink flow is restored.
(b) Soak the pen's tip in water as shown below, gently tap the other end of the pen several times, then try
writing with the pen. Repeat this several times until the ink flow is restored.
The combined use of methods (a) and (b) is recommended.
(c) Using an ultrasonic cleaner, clean the pen's tip by soaking it in water.
This method is even more effective when used in combination with methods (a) and (b).
NOTE
Use the ultrasonic cleaner according to the instructions provided in its accompanying manual.
