Solutions When vertical banding (horizontal to the printing direction) appears, or the paper is smeared, clean the paper path. & "Cleaning the Paper Path for Ink Smears" on page 72 The paper is curled. Solutions Place the paper on a flat surface to check if it is curled. If it is, flatten it. The print head is rubbing the surface of the paper. Solutions When printing on thick paper, the print head is close to the printing surface and the paper may be scuffed. In this case, enable the reduce scuff setting. If you enable this setting, print quality may decline or printing may slow down. ❏ Control panel Select Settings > General Settings > Printer Settings, and then enable Thick Paper. ❏ Windows Click Extended Settings on the printer driver's Maintenance tab, and then select Thick Paper and Envelopes. ❏ Mac OS Select System Preferences from the Apple menu > Printers & Scanners (or Print & Scan, Print & Fax), and then select the printer.

Solutions When performing manual 2-sided printing, make sure that the ink is completely dry before reloading the paper. When printing using automatic 2-sided printing, the print density is too high and the drying time is too short. Solutions When using the automatic 2-sided printing feature and printing high density data such as images and graphs, set the print density to lower and the drying time to longer. & "Printing on 2-Sides" on page 39 118
