Are you printing on pre-punched paper? Does a message appear indicating the need for maintenance? Are you using paper that is not within the specifications? Did you set the correct paper type? Is the paper loaded so that printing takes place on the reverse side? Is a suitable paper weight set? Solution Clean the scanning areas of the document glass or automatic document feeder. ☞ 1. BEFORE USING THE MACHINE "MAINTENANCE" (page 1-69) Clean the surface of the bypass feed roller. ☞ 1. BEFORE USING THE MACHINE "MAINTENANCE" (page 1-69) Use SHARP-recommended paper. Using paper that is for other models or special paper that is not supported may result in misfeeds, creases, or smudges. ☞ "SUPPLIES" in the Safety Guide Take care that the image does not overlap the punch holes. If the printed image overlaps the punch holes, smudges may appear on the reverse side of the paper following one-sided printing, or on both sides following two-sided printing. Contact your dealer or nearest SHARP Service Department as soon as possible. Use SHARP-recommended paper. Using paper that is for other models or special paper that is not supported may result in misfeeds, creases, or smudges. ☞ "SUPPLIES" in the Safety Guide Set the correct paper type in the tray settings. Make sure that the following has not occurred: • Heavy paper is being used, but a paper type other than heavy paper is selected in the tray settings. (The image may disappear if rubbed.) • Paper other than heavy paper is being used, but heavy paper is selected in the tray settings. (This may cause creases and misfeeds.) ➞ System Settings > "Paper Tray Settings" > "Tray Settings" Check that the paper is loaded so that printing takes place on the correct side. If printing takes place on the wrong side of label sheets or transparency film, the toner may not adhere well and a clear image may not be obtained. Setting a suitable paper weight in the system settings (administrator) may improve toner adherence. ➞ System Settings (administrator) > "Device Control" > "Fusing Control Settings" 8-52 Contents
