Now I bought a 920XL (up to 2.5X More) black cartridge from Office Depot...inserted it and Bingo ... it shows full, but now a have a print system failure. Cartridges will not align. I followed the clean up process and shut for 30 seconds.. Great Scott. I look on the Internet and a lot of people complain about the Made in China HP genuine cartridges. Unfortunately I don't have any more time as I have to fax important paper tomorrow so I will go to Office depot, try to get my money back (bought 2 920XLs plus the color combo under their sale offer for $66). I was printing just fine until I ran out of black ink and put the new cartride in. Printer has worked just great and I have put in a number of ink cartridges. I will buy a Canon...for Pete's Sake where is HP's quality control!!!!!! These are my opinions only.
