How make out the difference the ink cartridge that needs refill and that dried out? -

i have ink cartridge whose ink was low...and after that i did not use it 6 days...but now i do not know whether the cartridge is dried or it just needs refill.could anybody help me out?

Probably dried out. Get a CISS for your printer. It will save you TONS of MONEY, never change a cartridge again and it will pay for itself in a month. http://www.inkproducts.com/ink-store/
