We have purchased the 92/20 staples paper for years however we are now running into an issue with the paper sticking and pulling blank pages as we print. We buy by the case and it is roughly every other ream that has the issue. When looking at the ream you can see a definite color difference (bright white and pale yellow) and don't know if the product is being mixed with varying textures and that is what is causing the problem. As i said we use this product all the time and i would recommend however if the next case has the same issue i wouldn't recommend and we will need to switch brands.
