   Presuming that the machine hasn't gone out of basic alignment, which is rare, the only real adjustment on a jointer is the height of the outfeed table.  The only other cause for all sorts of problems on a jointer is having dull blades, so, if your blades are sharp, try this to set the outfeed table height (this should be done anytime you change blades or can't seem to get straight cuts) :

   Start by setting the infeed table to take a moderate depth cut, around 1/16th of an inch.  Now also lower the outfeed table until it is also about 1/16th inch below the cutter height.  Take two  reasonably straight boards, 30" to 36" long, and take a pass to joint one edge of each board. 

   The jointed edges probably won't be straight if you place them together and you should see a clear snipe on the last inch or so of the edges.  Now slightly raise the outfeed table and take another pass on each board, the new edges should be straighter and have less snipe.  Keep raising the outfeed table, a bit at a time, and testing the straightness of the two boards until the edges come together perfectly. 

   If you overshoot the setting, back off and try again rather than trying to slightly lower the now too high outfeed table.  This is an easy quick adjustment to make with a crank type outfeed table height adjuster, it can be considerably harder to do with a lever type adjuster.

   This will probably solve your problem, let me know how you make out.
