We go through at least 40-50 reams of paper every week and find that this paper is not worth the inexpensive price. The paper has a tendency to double up causing staff time and energy to separate out the blank pages from the ones printed/faxed. Was used in multiple printers faxes and copy macines with similar results in all. It is worth the extra pennies to use another paper.
The bright white color of this copy paper from Staples makes all my copies look great--the print stands out which is important to me. If a copy machine does not produce great looking copies that reflects negatively on me. I prepare income tax each year and my clients need a clean crisp copy of this very important document. It needs to last through the years. I also use this paper for personal projects and correspondence. Again this paper makes even quick letters to friends look like something special.
The 20 lb paper does not seem to work as well in our copy machine. We seem to have more issues with paper jams when using it versus the heavier weight papers. It works fine in printers.
