How Do You Put Ink In An Printer?

Are you trying to put ink into the cartidges themselves?  If so, it's a messy and nasty job, even with the kits  that you can buy (I've tried it, and went back to buying the new, already filled cartridges).  If you're trying to insert the cartridge, most printers, when opend up, will have small illustrations inside (near the cartidge opening) that show you how to insert them properly (this is if you don't have a manual for the printer).  I use a flashlight and magnifying glass when I need to see it).  If you have an HP printer, the front usually opens, (you have to leave it on), and the rod holding the cartridges will separate them for removal and insertion.  As a last resort, you can use a search engine like Google, type in the company that manufactures your printer, then on their site, look up your model, and then go to it's manual to see how the new ink is put in.

What brand is it and look in the manual or look it up on line
