What should I do if the pen has no ink?

If the pen is out of ink, you can try the following coup:

1. Check whether the ink bag or cartridge of the pen is dry. If it is dry, you can exchange it for a new one.

2. Soak the pen tip in warm water to help the ink flow again.

3. Shake the pen gently and let the ink re-wet the nib.

4. Wipe the nib gently with a soft cloth or paper towel to remove the ink that may be blocked.

If all the above methods fail, you can try tapping on the paper with a pen tip to help the ink flow again.

If the above methods still fail, you may need to send the pen for repair or replace it with a new one.
