PG-830, original will save you at the end
I have Canon MP145 for my compelete office purpose (copier, scanner and printer) for more than 4 years. So far, it provides good service. As we have already known, the printer with ink cartridge needs to replace the cartridge for certain time of period. And looking for cartridge, it is going to be easy to be seduced by refill method, instead of replacing the cartridge with new one. Even there are so many choices for these refill with so many easiness and offers.
I have been trying with refill (the yellow box). At the beginning. I felt satisfied, but I did not realize, though it works for Canon, as the printer is pushed to accept unidentified ink, the printer capabilty is got unpleasant impacts. Basically, I have to conduct 'maintenance' to keep my printing result as I expected, which finally I have to face that the printer need to readjust/service due to improper ink refill. The Canon guy said that no matter the refill ink claim for compatibility,in in fact, they are not Canon, the one who understand what the original Canon printer is made for. Then it makes me back to the original.
However, comparing to other original cartridge, Canon really needs to create cartridge with cheaper one. The Canon competitor has already made a good breakthrough: original cartridge with price lower than IDR 100K, with claim for printing more than thousand pages. Creating cheaper cartridge, will force the Canon user to keep loyal to the original and enjoy all the best of Canon
