Troubleshooting > Problems with the printing quality > Cause Corrective Action You are printing on paper that curls easily. Printed colors may appear uneven on the leading edge of paper that is susceptible to curling. Select a stronger level in VacuumStrngth in the Control Panel menu to increase suction against the paper, or specify a leading margin of 20 mm (0.79 in) or more. (See "Adjusting the Vacuum Strength (VacuumStrngth).") →P.852 Printed colors may be uneven if you set the Print Quality too low. Choose a higher level of Print Quality in the Advanced Settings of the printer driver. Printing in Draft or Standard mode is faster and consumes less ink than in Highest or High modes, but the printing quality is lower. (See "Giving Priority to Particular Graphic Elements and Colors for Printing.") →P.51 Color may be uneven between dark and light image areas. Select Unidirectional Printing in the Advanced Settings of the printer driver. When borderless printing is used, the edge of the paper is cut during printing. Thus, ink density may be slightly uneven at the leading edges. Specify No in Auto Cut in the printer driver before printing. In this case, the paper can be printed without borders on the left and right sides only. Cut the printed document ejected from the printer, and then use scissors or a cutting tool to cut away the edges on the top and bottom. Choose a higher level of Print Quality in the Advanced Settings of the printer driver. (See "Giving Priority to Particular Graphic Elements and Colors for Printing.") →P.51 The Printhead is out of alignment. Adjust the Printhead alignment. (See "Automatic Adjustment to Straighten Lines and Colors (Head Posi. Adj.).") →P.839 Allowing printed documents to dry on top of each other may cause uneven colors. To avoid uneven colors, we recommend drying each sheet separately. Density may be uneven if you use Glossy Paper or Coated Paper. In Advanced Settings of the printer driver, choose Highest or High in Print Quality. The type of paper specified in the Load paper of the same type as you have specified in the printer driver. 12 printer driver does not match the type loaded in the printer.

(See "Setting the Blue Switch on the Platen.") →P.1063 When printing fine lines or text at high precision on glossy or semi-glossy photo or proofing paper, set the optimal Printhead height before aligning the printhead.
