Did you clean the laser unit? Did you execute Dark Streak Reduction of system setting? Solution ■ Clean the scanning areas of the document glass or automatic document feeder. CLEANING THE DOCUMENT GLASS AND AUTOMATIC DOCUMENT FEEDER (page 1-66) ■ Clean the surface of the bypass feed roller. CLEANING THE BYPASS FEED ROLLER (page 1-72) ■ Clean the laser unit. For details on cleaning, refer to the CLEANING THE LASER UNIT (page 1-69). ■ Execute in "Settings (administrator)" → [System Settings] → [Image Quality Adjustment] → [Collective Adjustment] → [Dark Streak Reduction].

Dark Streak Reduction (page 9-204) SMUDGES APPEAR ON PRINTED OUTPUT Check Solution Are you using paper that is not within the specifications? Are you printing on pre-punched paper? Does a message appear indicating the need for maintenance? Remove the paper, turn it over, and reload it. Using a different paper type may solve the problem. ■ 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 Start Guide ■ Try setting the paper type to a type that is slightly heavier or slightly lighter than normal. (For plain paper, switch plain paper 1 to plain paper 2 or plain paper 2 to plain paper 1.) Depending on the paper type, print quality may be improved. For details, contact your dealer or nearest authorised service representative. ■ 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 1-sided printing, or on both sides following 2-sided printing. ■ Contact your dealer or nearest authorised service representative as soon as possible. ■ This may improve some states of paper curling.
