Sometimes ago, I had no knowledge of filling or refilling the ink in hp cartridge. Recently, I went to my friend’s cafe and learned his way to fill ink in HP Cartridge. In this, video, I have explained what my friend did.
My friend has more than 4 years experience re-filling ink cartridges at his Internet cafe.
Important Point to be remember :
If your cartridge is not working, please boil some water on heater and then wet your cartridge with this boil water for 4 to 5 minutes, after this, your cartridge life will be long.
