User's Guide
To avoid uneven colors, we recommend drying each sheet separately.
In Advanced Settings of the printer driver, choose Highest quality 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 Feed Slot.")
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.
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.
When Scan Wait Time > Area is set to Leading edge, colors may be uneven 110–140 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.
(See "Menu Settings.")
