Hollow print
■Make sure that you use paper that meets our
specifications. See What kind of paper can I use? in
Chapter 1.
■Choose Thick paper mode in the printer driver, or use
thinner paper than you are currently using.
■Check the printer's environment because conditions
such as high humidity can cause hollow print. See
Positioning the printer in Chapter 1.

■Make sure the paper or other print media is loaded
properly in the paper tray and that the guides are not
too tight or too loose against the paper stack.
■Set the paper guides correctly. Make sure that the
tips of the paper guides fit firmly into the slots.
See Printing from the Paper tray in Chapter 1.
■If you are using the multi-purpose tray, see Printing
from the multi-purpose tray in Chapter 1.
■The paper tray may be too full. See Printing from the
Paper tray in Chapter 1.

and high humidity will cause paper to curl. See What
kind of paper can I use? in Chapter 1.
■If you don't use the printer very often, the paper may
have been in the paper tray too long. Turn over the
stack of paper in the paper tray. Also, try fanning the
paper stack and then rotating the paper 180° in the
paper tray.
Wrinkles or creases

from the Paper tray in Chapter 1.
