TROUBLESHOOTING Problem Smudges appear on printed output. Point to check Are you using paper that is not within the specifications? 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. Are you printing on pre-punched paper? 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. Take care that the image does not overlap the punch holes. Is the laser unit, the main charger, or the PT charger dirty? If these units are dirty, smudges appear upon print results.

(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" Is the paper loaded so that printing takes place on the reverse 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. Print quality is poor. Is "Toner Save Mode" enabled? When "Toner Save Mode" is enabled, printing takes place using less toner and thus the print result is lighter. Check with your administrator. Part of the image is cut off. Has the correct paper size been set? If you are using a special size, be sure to specify the paper size. If the size of paper loaded in a tray was changed, be sure to check the paper size setting. ➞ System Settings > "Paper Tray Settings" > "Tray Settings" Was the original placed in the correct position?
