<Cause 1> "Line Drawing/Text" is selected when printing images in many solid colors.
<Corrective Action>
In "Print Priority" in the "Advanced Settings" of the printer driver, choose "Image".
<Cause 2> You are printing on paper that curls easily.
<Corrective Action>
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.
<Cause 3> Printed colors may be uneven if you set the Print Quality too low.
<Corrective Action>
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.
<Cause 4> Color may be uneven between dark and light image areas.
<Corrective Action>
Select "Unidirectional Printing" in the "Advanced Settings" of the printer driver.
<Cause 5> 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 1>
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.
<Corrective Action 2>
Choose a higher level of "Print Quality" in the "Advanced Settings" of the printer driver.
<Cause 6> The Printhead is out of alignment.
<Corrective Action>
Adjust the Printhead alignment.
<Cause 7> Allowing printed documents to dry on top of each other may cause uneven colors.
<Corrective Action>
To avoid uneven colors, we recommend drying each sheet separately.
<Cause 8> Density may be uneven if you use Glossy Paper or Coated Paper.
<Corrective Action>
In "Advanced Settings" of the printer driver, choose "Highest" or "High" in "Print Quality".
<Cause 9> The type of paper specified in the printer driver does not match the type loaded in the printer.
<Corrective Action 1>
Load paper of the same type as you have specified in the printer driver.
<Corrective Action 2>
Make sure the same type of paper is specified in the printer driver as you have loaded in the printer.
1. Press the "Stop" button and stop printing.
2. Change the type of paper in the printer driver and try printing again.
<Cause 10> Colors may be uneven at the trailing edge when you print on heavyweight sheets even if you execute "Adj Far Ed Feed".
<Corrective Action>
For heavyweight sheets or similar paper, execute "Adj Far Ed Feed" with the Front Tray Guides raised. Also keep the Front Tray Guides raised during printing.
Lower the Front Tray Guides when printing on paper other than heavyweight sheets.
