This is really a rip off. I had nearly 25%of my black ink left when the light started blinking on the printer. I saw that one of the color cartridges had a yellow exclamation point, so I replaced it. Now, without having printed anything I now have exclamation marks on all of the cartridges. The other two color cartridges were low, so i replace them. Now this POS printer says there is no black ink left and it wil print nothing. You are a bunch of crooks!!! There is plenty of ink in there and you have designed these things to say they are empty just so you can rip me off for more ink. Look, I have been bloody robbed by your company enough. I already had to return my All in One machine to you with a full black ink cartridge, I might add and I had to pay for it. It was supposed to be free but you neglected to put in the stickers when you shipped me the replacement. Now this! I will be posting this on my 60,000-member computer forum this evening. I hope that you lose a lot of business. I do not want to see others ripped off by your miserable company. You have cheated me for the last time. Now, this time you folks are going to PAY!!!!
