HP LaserJet Professional CP1020 Series keeps double/multi page feeding on two sided print

[Shinerwright50]

Pages stick together on re feed and it appears that the anti-staticxc brush is not wiping the paper correctly.  is this related to the moisture contect of the paper?

@Shinerwright50 Are you referring to the HP LaserJet 1020 Model, as the one you've mentioned does not have automatic two-sided printing feature, refer to this article to confirm product specifications: Click here 

Please re-confirm the model number, and if it turns out to be the above model, I'm afraid that's a commercial device:

@Shinerwright50 I appreciate the screenshot, as it helps me explain the fact that this printer does not support automatic two-sided printing, what you've been doing is manual work and if the feeder isn't picking up the paper as it should, and you've tried multiple paper types, yet have the same issue, this could be a hardware malfunction.

If the issue occurs only on one particular paper type, it could be because of the moisture contact of the paper as you've rightfully mentioned.

(I hope that helps clarifies my post and answers your query).
