Review on MIROO Replacement Ink Cartridge for HP 932XL 933XL: Compatible with HP Officejet 6700 6600 7612 6100 7610 7110 Printers - 2 Black, 1 Cyan, 1 Magenta, 1 Yellow, 5-Pack by Ryan Barton

This product does not fit my sister's printer. There was a warning from HP that might not work. However, when I installed it, it didn't work. This works to an extent when printing from a computer, but when printing from a phone or tablet, black results in yellow or blue. He has a mind of his own. So she can still use it to print text in black only. Many Thanks. Hello Alice, I did what you advised me to do. I took all the ink out of my sister's printer (HP 6600), gave it a good shake and put it back in, and it WORKS when I'm printing a document in both black and color. Many Thanks. I give it 5 stars (*****) Sent from my iPhone on Feb 27, 2018 10:53pm smartjet – Revain Marketplace <wmc32cwmz32zw1v@marketplace.amazon.com> wrote: Order ID 112-0827564-2502669: - ------------ Start of message ------------- Message from 3rd party: Hi Savat, this is Alice from MIROO, I saw re. you see you're gone I am sorry for the delay in replying. Can you tell us your printer model? If you encounter this problem, take the cartridges out of the printer, shake them vigorously for about 2-3 minutes, cover the ink hole with a piece of paper (with the ink hole facing down when shaking), and set it aside for a few minutes. then wipe the chip with an eraser and install it, after that use the "Print Head Cleaning" function about three times to allow the ink in the cartridge to flow out well. to offer you a pleasant shopping experience. So would you like to accept a replacement to test again? I hope you forgive us. I really want to help you solve this problem, thanks for your time. I am looking forward to your answer. Kind regards Alice, Hi Alice, I did what you suggested. I took all the ink out of my sister's printer (HP 6600), gave it a good shake and put it back in and it WORKS printing a document in black plus two color photos. Many Thanks. I give it 5 stars (*****) from Savath Yin
