1. Characteristics and Conditions of Paper 1. Print on paper under the following printing conditions: • One-sided printing • Print 10 sheets • Output the paper with the printed side face down 2. Place the curled paper on a table or flat surface with the curl facing up. 3. Measure the height of the tip of the curl at each corner of the stack of paper. Do this measurement within one minute after printing. • If the weight of the paper is 221 g/m2 or more, measure one sheet of paper. Cut Edge The condition of the cut edge of the paper affects print performance. Use paper that has a clean edge with no burrs. Cut paper is made by stacking many sheets together and cutting them. The cut edge of paper cut with a sharp cutter is straight, but if the cutter is dull, then the cut edge is uneven and has thin protrusions on the edge of the paper. These are called burrs. 1 2 CEL007 1. Cut edge from a dull cutter 2. Cut edge from a sharp cutter Burrs may cause the paper to feed at an angle, feed multiple sheets at one time, or result in misfeeds through the machine. They may also cause paper jams in the machine and shorten the life of the fusing unit. If a paper jam occurs, turn over the paper in the paper tray. Changing the orientation of the burrs can reduce the tendency for paper to jam. Remove as much of the paper dust particles caused by the burrs as possible. These particles may reduce the print quality. 12
