Cause
When borderless printing is used, the
edge of the paper is cut during printing.
Thus, ink density may be slightly un-
even at the leading edges.
The Printhead is out of alignment.
Allowing printed documents to dry on
top of each other may cause uneven
colors.
Density may be uneven if you use
Glossy Paper or Coated Paper.
The type of paper specified in the print-
er driver does not match the type loa-
ded in the printer.
Scan Wait Time > Area in the Control
Panel menu is set to Leading edge.

Cause

User's Guide
Specify No in Automatic Cutting in the printer driver before printing. In this case, the pa-
per can be printed without borders on the left and right sides only. Cut the printed docu-
ment ejected from the printer, and then use scissors or a cutting tool to cut away the
edges on the top and bottom.
Choose a higher level of Print Quality in the Advanced Settings of the printer driver.
(See "Giving Priority to Particular Graphic Elements and Colors for Printing.")
Adjust the Printhead alignment.
(See "Automatic Adjustment to Straighten Lines and Colors.")
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.
Press the Stop button and stop 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 uneven 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.
