My Uncle got in touch with me awhile ago. He had put ink into his printer and it wouldn't work. In his case, he just forgot to take off the protective plastic strips of the ink cartridge.
But someone suggested to him he needed his printer Lined Up. I assumed he meant alignment. So if your printouts aren't coming out straight, here is how to align your printer. This is from my Canon Pixma MX492. I've noticed in my case that this print alignment only comes up after I put in a new ink cartridge. I just usually ignore it. But if your prints are not coming out right. Then do the following.
First in the searchbar type Printers and Scanners and click on it when it appears in the menu list. Find your printer listed and click on it. Then click on Manage.
In the next window, click on Printing preferences.
Then click on the Print Head Alignment icon.
Click on Align Print Head button first if you are having problems. Then click on Print Alignment Value. If you're not having problems or just replaced the ink, I recommend just clicking on the Print Alignment Value button.
It will tell you to make sure there is paper in your printer.
Then it will warn you about starting anything else before it's finished. Just click on OK.
This will print up a page. This is what my Canon page looks like.
Everything looks straight and normal. So now I have to put it in the scanner and press the colour scan button. Only repeat if you still have problems. Otherwise, like I said, when I put in new ink, I always ignore this warning and so far no problems.
