Operation Manual

Symptom What to do
The printed surface is scuffed or
soiled.
Is the paper too thick or too thin?
Check that the paper specifications are compatible with this printer. For information
about the media types and appropriate settings for printing on paper from other
manufacturers or when using RIP software, see the manual supplied with the paper, or
contact the dealer of the paper or the manufacturer of the RIP.
Is the paper creased or folded?
Do not use old paper or paper with folds in it. Always use new paper.
Is the paper wavy or slack?
Cut sheets become wavy or slack due to changes in temperature or humidity which may
result in the printer being unable to recognize the paper size correctly. Flatten the paper
before loading it in the printer, or use new paper.
Is the print head scuffing the printed surface?
If the printed surface of the media is being scuffed, set the Platen Gap between Wide and
Widest from the Menu.
U “Printer Setup menu” on page 103
Is the print head scuffing the edge of the paper?
Set the Roll Paper Margin to Top 35/Bottom 15mm from the Menu.

Widen the bottom margin
Depending on the paper usage, storage conditions, and the content of the print data, the
bottom edge may be scuffed when printing. In this situation it is best to create your data
with a wider bottom margin.
The paper is creased.
Are you using the printer at normal room temperature?
Epson special media should be used at normal room temperature (temperature: 15 to 25
˚C, humidity: 40 to 60 %). For information about paper such as thin paper from other
manufacturers that requires special handling, see the manual supplied with the paper.
When using non-Epson special media, have you made the paper configuration?
When using non-Epson special media, configure the paper characteristics (custom paper)
before printing.
U “Before printing on non-Epson media” on page 158
The reverse side of the printed
paper is soiled.
Set Paper Size Check to On in the Menu.
If the print image is larger than the paper width, printing normally stops. However, if
Paper Size Check is set to Off in the Menu, the printer prints on the paper exceeding the
paper width causing the inside of the printer to be soiled. To avoid soiling the inside of the
printer, set Paper Size Check to On in the Menu.

Is ink dry on the printed surface?
Depending on the printing density and media type, the ink may take a while to dry. Do not
stack the paper until the printed surface is dry.
Also, if you set the Drying Time per Page in Paper Configuration from the printer driver,
you can stop the operation after printing (ejecting and cutting paper) and wait until the
ink is dry. See the printer driver help for more details on the Paper Configuration screen.
While drying, the ink drying message is displayed on the screen. You can cancel drying by
pressing the OK button.
