A:Answer The 61 XL cartridge has over twice as ink as the Regular 61. When you go for a new cartridge, the XL will be slightly lower than 2X the regular 61.
I always by the XL black beacuse I do a lot of letter writing and don't use a lot of color, so buy the Regular 61 color cartridge. If you print out of photos that I would recommend the 61 XL color cartridge. It will be cheaper in the long run.
By the way, even though the your printer is not listed the 61 cartridge, those may be leftover carts that were out before your printer was.
If 61's came with your printer than that is the replacements you should use.
I hope this helps.
