Finally with "chips" on the nozzles, you can not have an empty nozzle whatsoever (also confirmation Canon). Formerly, you could remove the color nozzles and request that black prints. There, the machine hangs from a nozzle is missing. I have not tried them compatible without "smart", but in my opinion, it banned completely. So before attempting without chip compatible, buy a nozzle and test drive (you will then stocks).
Finally, latest find Canon ink nozzles particular color are less "satisfied" that on older models but the price is even more expensive than for previous models. What is called being had on 3 tables as prices that do not change except for certain products that we forget to say that he no longer 250g goods, but 220 and tomorrow we'll finish at 50. ... THUS, circulate so they put pressure on CANON. Why, apart from the good quality product, I put a ZERO POINTE because the beauty of the body I will, but I have not bought a Rolls, I have not got the means !!!
NB 6/12/2011: A user has made the calculation of cost per liter ink ..... we reach 1580 euros per liter (it is better to sell it than oil).
