To avoid uneven colors, we recommend drying each sheet separately.
In Advanced Settings of the printer driver, choose Highest or High in Print
Quality.
Load paper of the same type as you have specified in the printer driver.
(See "Loading Rolls in the Printer.")
(See "Loading Sheets in the Printer.")
Make sure the same type of paper is specified in the printer driver as you
have loaded in the printer.
1. Hold down the Stop button for a second or more to cancel printing.
2. Change the type of paper in the printer driver and try printing again.
When Scan Wait Time > Area is set to Leading edge, colors may be un-
even 110–160 mm from the leading edge. (The position varies depending on
the Print Quality setting.)
In this case, select Scan Wait Time > Area > Entire area.
However, note that printing will now take longer.
