I did my focus adjusting thanks to these instructions (THEY WORKED WITH K10d firmware 1.10 - It is no longer available on Pentax site as they replaced it by 1.11)
Pentax DSLR focus correction
If your Pentax *istDL v1.03, *istDL2, *istDS v2.02, *istDS2 v1.02, K100D v1.02, K110D v1.02 or K10D v1.10 is not focusing right, there's remedy for your camera that comes with newest firmware update. Get your latest firmware update first from the http://www.pentaximaging.com/customer_care/software_firmware?sfFlag=f and then follow the steps below. Prior to changing mode to debug, I switched to central AF point. It's easier to see what you're focusing on. Grid value on the following examples - 0.1 inches (2.54mm). Photographed at 45° angle, a step of the ruler = 5um AF correction.
K10D series DEBUG STEPS
1. Your K10D' firmware version must be 1.10.
2. Test shot for focus trouble.
3. Turn the camera OFF.
While pressing [PLAY]+[OK], Turn the camera ON.
You can see firmware version on LCD screen.
4. Firmware version is appeared,
then press [Fn]->[Fn]->[INFO]->[MENU] within 5 seconds.
You get service menu!!!
5. by pressing [right key],change DEBUG MODE [DIS] to DEBUG MODE [EN].
then press [OK].
(save and LCD will be black out)
6. Press [MENU] and go to SETUP tab.
then, Press [^Up key], you can see TEST MODE.
7. Select AF TEST menu. now you have AF correction menu.
If you have Front-focusing, reduce the value.
If you have back-focusing, increase the value.
after adjust some value, press [OK] and quit out of setup menu.
8. TEST for focus, find out that focus is correct.
(repeat this from 6 for correct focus.)
9. Go to service menu(step 3,4).
change DEBUG MODE [EN] to DEBUG MODE [DIS].
then press [OK]. (save and LCD black out)
I used ruler photographed from macro distance at 45° angle. Autofocused precisely on a 4.5 line (maybe a little above. Picture below comes with corrected AF point, picture above appear backfocused. If your camera is front-focusing, reduce the value, if it's backfocusing - increase the focus correction value.

I adjusted the K10 to +350 microns and the improvements speak for themselves. First attempt at this, this was with the Tamron 28 - 300 which backfocussed. This picture was focussed half way across the face of the flower head. Taken on a tripod with SR off and 2 second delay with mirror up to eliminate shake. As an aside I have noticed how the K10 has a huge "clunk" as the shutter operates compared to the soft "glide" of the k20.
