We recommend printing curl-corrected paper one sheet at a time. Note Depending on the media type, the paper may be smudged or may not be fed properly even if it is not curled inward. In such cases, follow the procedure described below to curl the paper outward within 0.1 inch / 3 mm (B) in height before printing. This may improve the print result. (C) Printing side We recommend printing paper that has been curled outward one sheet at a time. Check 4: If you are printing on thick paper, select the Prevent paper abrasion setting. Selecting the Prevent paper abrasion setting will widen the clearance between the Print Head and the loaded paper. If you notice abrasion even with the media type set correctly to match the loaded paper, set the printer to prevent paper abrasion on the computer. Print speed may be reduced if you are selecting the Prevent paper abrasion setting. * Deactivate the Prevent paper abrasion setting once printing is complete. If not, this setting remains enabled for all subsequent print jobs. Open the printer driver setup window, and in Custom Settings in the Maintenance sheet, select the Prevent paper abrasion check box, and then click Send. To open the printer driver setup window, see Opening the Printer Driver Setup Window . Check 5: If the intensity is set high, reduce the Intensity setting in the printer driver and try printing again. If you are using plain paper to print images with high intensity, the paper may absorb too much ink and become wavy, causing paper abrasion. Reduce the Intensity setting in the printer driver and try printing again. 1. Open the printer driver setup window.
