Query: Genuine Canon ink brought back my printer

I tried some inexpensive generic ink cartridges in my Canon i860 printer , but the inks didn't flow through the printer head, and I was worried that I had ruined my printer. But, after installing the genuine Canon Magenta and Cyan cartridges, my printer is now working fine again. Sadly, these Canon inks are not cheap , but short of buying other printers ( and I have two of them) I apparently have no choice.
