Troubleshooting
Colors are Unclear
■ Confirm the Media Type setting in the printer driver matches the type of paper
loaded in the printer.
If you are printing a photograph or an illustration from a Windows environment, also
increase Print Quality on the Main tab.
If you are working in a Macintosh environment, select Photo or Graphic for the Print
Mode in the Print dialog box.
■ Confirm the specified ink tank is installed.
When an ink tank runs out of ink, replace it with a new one.
Note ➤
Printed colors may not match screen colors perfectly due to basic
differences in the methods used to produce colors. Color control settings
and environmental differences can also affect how colors appear on the
screen.
