It could be a slight "clog" or something on the face of the head deflecting
the jet a bit.  If a cleaning cycle does not get it, try some Windex on a
strip of paper towel, or better, a 1/2 inch bias tape (cloth used in
sewing).  Move the head over the tape, grab the ends of the tape and pull it
back and forth over the face of the head.  While the wiper blades are
supposed to get the junk off, I sometimes have to resort to the bias tape
with Windex.  In my case, I think it's often dog hair that has gotten onto
the head.
