“In my experience, HP printers are very picky about using off-brand cartridges. After the first one of Ink Toner Store worked in our HP 7640, I thought we found a brand that would finally work. The next two cartridges would not work and the printer error messages would not clear. It kept telling us to remove the cartridges and reinstall it. No matter how many times we tried, we could never get it to work.”
“The drum is of poor quality, it leaves excess black toner on the page in the form of streaks and smudges. Would have given it zero stars if that was possible.”
“The HP printer prevents printing. So unless InkTonerStore tells us how to turn off this "dynamic security feature" of HP printers, the non-HP cartridges will nopt work. How do I get my money back please?”

“The ink toner has been leaving bad smudges on our papers even after troubleshooting the problem. They do not snap in tight either and I do think the smudges are due to the cartridges leaking ink. We have had a terrible time with them, I definitely do not recommend them because our papers are so black from them. We will have to go back to using the name brand. Highly dissapointed in the quality of these toner cartridges.”
“Going to have to figure out why it is only printing in monotone grey black may need to see if HP is blocking it for not being an original hp cartridge.”
