II. Replacement Steps 1. Open the pen holder: Most writing tools are designed with a twisting or sliding lock on the pen holder, which can be easily opened by twisting or sliding slightly. 2. Remove the old pen cartridge: Once the pen holder is opened, gently pull out the old pen cartridge from the holder. Take care not to use too much force to avoid damaging other parts. 3. Clean the pen holder: Use a clean cloth or paper towel to wipe the inside of the pen holder and the nib to ensure there is no ink residue. 4. Install the new pen cartridge: Insert the new pen cartridge into the pen holder, ensuring it is securely seated. Be careful with the direction of the new pen cartridge and do not insert it backwards. 5. Close the pen holder: Gently twist or slide the lock on the pen holder to ensure it is closed and locked tightly. 6. Test writing: Gently press the nib onto a piece of paper and write to check if the new pen cartridge is properly installed and functioning correctly. III. Precautions 1. When replacing the pen cartridge, ensure that the surrounding environment is clean to avoid any debris entering the pen holder. 2. Avoid replacing the pen cartridge in overly damp or overly dry environments, as this may affect its lifespan. 3. Do not use excessive force to pull out or insert the pen cartridge, as this may damage the pen holder or other parts. 4. If you find that the new pen cartridge does not work properly after installation, check if it is installed correctly or if there is a quality issue with the product itself. 5. Regularly check the condition of your pen cartridges during use and replace them promptly to ensure smooth writing and durability of your writing tools.
