hi, ive dealt with epson r800 with cis for 3 years now , ive changed around 6 machines and cis , the headache and mess it caused me was unbelievable . ive tried cleaning them ,chip reseting ,taking air out of the cis drilling holes in the epson for the ink waste ,program reseseting .everything worked for a while ,then i had enough , my freind advised me to get a canon ip 4500 and work just with original cartriges since i only print on cds,and like a fool i went and got a newer model ip4600 thinking it be better , until i came onto this forum i noticed that the opinion of the ip 4600 is bad . so i know someone whos got an ip 4500 and i asked him to swap with my ip 4600. hes had it for about a year and hasnt really used it that much , he just got it if he needed to print something . so what do u people think should i swap ????
