Review on 🖨️ LxTek Compatible Ink Cartridge: HP 902 XL 902XL Replacement for Officejet 6978 6954 6962 6968 6975 Printers (5 Pack) by Mark Callaham

I didn't turn off auto-update on my HP printer, so I received a BIOS update last December. When my printer ran out of ink last week (just when I needed it for work, of course), the printer refused to recognize the replacement cartridges I had (old chip). After reading the reviews I bought these LxTek cartridges. I bet black first. It was recognized immediately and I was able to print black and white documents straight away. However, I had a job that required a lot of color printing and knew the yellow cartridge was empty. I've tried setting just the new yellow, but it looks like my printer won't allow a mixed CMY set (old chips and new chips). So all three old color cartridges removed, new ones inserted and all were recognized without problems (just a message that it is not OEM, clicked on "OK" and that's it). However, after I printed a few color pages, my printer stopped printing yellow and green. This turned out to be a problem with dirty printheads. I don't usually print many colors so I'm thinking the color printheads are clogged or something (dry ink?). The solution was to run the printhead cleaning (every three stages each) a total of three times and finally everything worked again. Definitely a printer problem, not bad cartridges. We were able to successfully print the AKC rally signs (approximately 100 letter-size pages with large colored arrows, symbols and other graphics). These cartridges weren't the cheapest for Revain, but they still cost half the price of an OEM set. As far as I can tell, the print quality is as good as ever. HP OfficeJet 6958, so not a high-end printer. Note, however, that if you don't type much like me and most of the text is black and white, you may be dealing with dirty printheads.
