Yeh next time bro, just use leaves you can see tricomes on. Fans are not really much good. If they are not visible, bin it (or at least save them and run them separate - you will see that it's not really worth the time for the quality you get!). You looking for that good sugar leaf, for the high grade hash.
Also, and I can't emphasise this enough, remove any stalks you see. Even the stems for bigger leaves can cause a problem, as when stirring or using the machine these will tangle up with each other, you will be left with a ball of material - much harder to dislodge trichomes from the centre of this mass. Quality and yield will suffer!
Did you use fresh frozen material? Dried frozen material? How did you dry your hash? Drying and curing are Hugely important processes when it comes to the final quality of your hash. In my experience, this is the area where most mistakes are made/corners cut!
