Although using non-original cartridges does not really damage a printer, printer manufacturers generally attribute any printer defect to the use of non-original cartridges. This is because printer companies are trying to lock the consumers in buying their very expensive cartridges for selfish reasons. Thus, they void the printer warranty if they find out that the customer uses refilled or non-original cartridges.
The good news is that the savings that you will get from using the INK All-You-Can System is more than enough for you to buy as many printers as you want.
