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.
