Colors in printed images are uneven Cause Line Drawing/Text is selected when printing images in many solid colors. You are printing on paper that curls easily. Printed colors may be uneven if you set the Print Quality too low. Color may be uneven between dark and light image areas. 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. Corrective Action In Print Priority in the Advanced Settings of the printer driver, choose Image. 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.842 Choose a higher level of Print Quality in the Advanced Settings of the printer driver. Printing in Fast or Standard mode is faster and consumes less ink than in Highest quality or High modes, but the printing quality is lower. (See "Giving Priority to Particular Graphic Elements and Colors for Printing.") →P.64 Select Unidirectional Printing in the Advanced Settings of the printer driver. 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.
