Any way to adjust focus on K-50?

I've been reading around and it seems that a front or back focus sometimes happens with lenses. Is there a way to adjust that with the K-50?

Besides the way described on page 112 of the manual?

You can even get the manual as a pdf online.
Also, there are many threads and blog posts about this. Focus calibration is a common problem. You can use a chart, but there are various methods of going about it.
Generally, you should put camera on tripod, Av mode with lowest f-number, choose a really low ISO, 2 sec timer. Do not use live view, as that is a different focus type, which is always accurate, but slower.
Then switch camera to MF and defocus the lens. Place a subject somewhere in front of the lens, make sure its not too close (as every lens has some minimum focus distance under which it will never focus) and not too far. The subject has to be a big bright, contrasty object. And the background behind it should be far. Then turn on AF again and focus, take a shot, see how it works.
Again, there are threads and tutorials about this, many with links and detailed explanations and even other people's tests
