CCweems is exactly right. Following instructions in your manual, loosen the bolts holding ONE blade, shift it ever so slightly to one side or the other (makes no difference which) retighten, and the defect will go away. Tje blades nolonger cut the same track, so they cut out the defect left by the others. Works eveery time. The blades are reversible too, so when they get dull, flip them.

While you’re at it, clean the rollers with mineral spirits and do it regularly to prevent slipping. Unplug it, of course, whilst doing any of this.
