The pen is a common writing tool, and ink needs to be injected into the pen when it is used. The following steps are for the pen to absorb ink:
1. Prepare ink: select appropriate ink, open the bottle cap, and prepare the dropper or ink aspirator.
2. Prepare the pen: disassemble the pen body and remove the cap and refill. If it is a new pen, you need to clean the tip and the refill first to ensure that the ink can flow smoothly into the refill.
3. Ink suction: use a dropper or ink aspirator to drop ink into the pen core. If you use an eyedropper, you can insert the eyedropper into the center of the refill and gently press the eyedropper to let the ink drip into the refill slowly. If you use an ink absorber, you need to insert the ink absorber into the center of the pen core, gently press the ink absorber to let the ink be sucked into the ink absorber, and then pour the ink in the ink absorber into the pen core.
4. Install the pen refill: insert the pen refill into the pen body, and ensure that the pen tip is aligned with the pen body. Then cover the cap of the pen so that the pen core is in full contact with the pen tip.
5. Test writing: take off the pen cap and try to write on the paper to see whether the ink is smooth and the color is normal. If there is a problem, you can try to clean the tip and refill again, or replace the ink.
It should be noted that after each use, the pen core and pen tip should be cleaned to avoid the ink drying or blocking the pen core. In addition, the ink should be stored in a cool and dry place to avoid direct sunlight or moisture.
