Hello. My name is Michael. I can help you with your question. I'm assuming you've done the usual steps - when you replace a cartridge, it should run an alignment automatically - printing out a page which tells you to put it on the scanner. If not, you can do the alignment through the print driver as long as you have the HP software installed.
Step one: Finish the software installation

Press the Cancel button () on the control panel to stop the alignment.
