TROUBLESHOOTING Problem Smudges appear on printed output. Toner does not adhere well or creases appear in the paper. Print quality is poor. Point to check Are you using paper that is not within the specifications? Are you printing on pre-punched paper? Is the laser unit, the main charger, or the PT charger dirty? 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 "Toner Save Mode" enabled? Solution 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. For details, contact your dealer or nearest SHARP Service Department. 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. If these units are dirty, smudges appear upon print results. Clean these units periodically. For cleaning, see "Start Guide". 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. For details, contact your dealer or nearest SHARP Service Department. 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. Check with your administrator. When "Toner Save Mode" is enabled, printing takes place using less toner and thus the print result is lighter. 8-47 Contents
