Last month, the printer got out of order and we had it repaired. After I took my printer back to my home from the shop, I didn't notice the ink (only blue one) was leaking!
Luckly, the ink didn't spread out any place except my hands. It took much time the ink was gone rather than I thought. Everytime I saw my hands, I was surprised with myself only a little bit haha.
