If you see a border on borderless prints, try these
solutions:
Make sure
you are printing on a compatible borderless paper type and size.
Note: For
custom paper sizes, make sure you select a supported borderless
page width.
Windows: Make sure you selected
the Borderless setting in your
printer software.
Mac: Make sure you selected the
Borderless checkbox or a paper
size with a Borderless option in
your printer software.
Adjust the
Expansion setting to adjust the
amount of image expansion on the edges of borderless prints.
Make sure
the image size and the paper size are set correctly; if the image
is small, the enlargement may not be enough to cover the
paper.
Make sure you have stored the paper correctly. Paper
can expand or contract if it is not stored properly. See the
instructions that came with your paper for storage
instructions.
