I. Preparation 1. Confirm the pen type: Determine your pen type to ensure you are using the correct replacement procedure. 2. Prepare a new refill: Take out a new refill from its packaging and inspect it for any damage. 3. Gather tools: While replacing the refill generally doesn't require special tools, having some (such as a pen refill puller) may make the process easier. II. Replacement Steps Taking a common ballpoint pen as an example: 1. Remove the old refill: Hold the pen body and gently pull out the old refill. If it's stuck, use a tool or try other methods (such as tapping the pen lightly). 2. Check the new refill installation port: Ensure that the new refill, which usually has ink at one end, fits the installation port and is clean and without debris. 3. Install the new refill: Insert the new refill into the pen body, making sure it is fully inserted and secured. Avoid applying too much force that could damage the internal structure. 4. Test the writing: Gently press the new refill and test writing to ensure smooth writing. III. Notes during the Process 1. Avoid excessive force: Be cautious not to apply too much force when pulling or inserting the refill, as this could damage the pen body or refill. 2. Keep it clean: During the process, keep your hands clean to avoid ink staining other items. 3. Proper storage: Unused refills should be stored in a dry, cool place, away from direct sunlight and damp environments. 4. Follow instructions: If you have any doubts or special circumstances, follow the product instructions or contact the manufacturer for assistance.
