1, the seal is out of ink. Buy a bottle of ink and add it. The general step of oiling photosensitive seal is to invert the seal, pour in special ink word by word, wait for the ink to penetrate 10 minutes or more, then wipe off the excess ink with a paper towel before continuing to use it.

2. When the machine carving penetrates the seal to refuel, first open the bottom cover of the seal, and then add printing oil to the text. To add ink to the ink return seal, first press the button, take out the ink pad, then add ink to the ink pad, and finally put the ink pad back in place and stamp it directly.

3. If it is a machine-carved infiltration seal, infiltration ink or atomic ink can be added. Photosensitive printing oil must use special photosensitive printing oil. Mechanical pressure atomic seal is a disposable seal and cannot be reused by oil injection.

If the seal is out of ink, add the matching ink, pour the special ink word for word, and wipe off the excess ink after the ink permeates.
