The Royal 1840MX is an ideal desk side and personal shredder for any home office. Operation is simple. The 1840MX will automatically start when paper is fed and stop when the last sheet is destroyed. If a paper jam occurs, this shredder automatically switches into reverse mode to remedy the jam. Shredding about 18 sheets per pass, the Royal 1840MX offers a continuous run time of 40 minutes. This heavy-duty commercial grade shredder destroys not only paper, but also staples, paper clips, credit cards, CD’s and DVD’s. Your paper and accessory materials are broken down into 5/32 x 1 3/8 Inches particles. These shredded particles fall into a 9 gallon pullout wastebasket with a window, allowing the user to see exactly when the bin needs to be emptied.
