Printer Ink Refill – Damaged Cartridge
While searching for filling up printer cartridge at home i tried refilling my printer ink at home. Purchased ink and a injection to fill my cartridge. I watched some videos on how to fill the printer in on you tube. On you tube it was showing cartridge same as mine one i followed all the steps but when i put it into my printer its not working nothing is getting printed out. I filled my printer ink full till top and pull back some ink through bottom of the cartridge also.
I just did this with black color cartridge to save some bucks but its not working and its not even empty. My cartridge no is 27b which is for hp printer 3740 desk-jet series. Is there any way i can get this cartridge empty so that i can send it for refilling to some expert?? Or is there any thing which i am missing while refilling ink cartridge.
Any kind of help will be useful. Please suggest me what to do..
Here is how my cartridge looks like..
