My MG6120 Canon is near the bottom of each cartridge and I can no longer use tricks to get it to print black and white when the color cartridges are out. Yes, I'm sure I need yellow to print grayscale. Due to the extra high cost of OEM cartridges, I believe I have three options - buy generic cartridges, buy a refill kit, or buy a new printer. Since the scanner still works very well on this I'd prefer to just keep it. Doing a lot of research it seems all the generic replacement cartridge and refill kit info is mostly on HP and a few Epson printers. Doing a search for "best inkjet refill" gets me to some ancient PC World articles that are specifically for the HP printers, but still contain useful info for those printers, not Canon. A search for "best MG 6120 inkjet refill" just takes me to Amazon sale pages for model specific parts. That doesn't tell me what actually works, and neither do the reviews. An hour later, I figure I'd just ask people who've already walked this road. Did you get refills or generic cartridges? What sources can you recommend?
