Hollow print
■ Make sure that you use paper that meets our specifications. See What kind
of paper can I use? on page 1-5.
■ 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 on page 1-4.
Page skewed
■ 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.
■ If you are using the multi-purpose tray, See Printing on plain paper from
the multi-purpose tray (MP tray) on page 1-13.
■ The paper tray may be too full. See Printing on plain paper from the paper
tray on page 1-10.
■ Check the paper type and quality. See What kind of paper can I use? on
page 1-5.
Curl or wave
■ Check the paper type and quality. High temperatures and high humidity will
cause paper to curl. See What kind of paper can I use? on page 1-5.
■ 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,
fan the paper stack and then rotate the paper 180° in the paper tray.
■ Print using the straight-through output path. See Printing on plain paper
from the multi-purpose tray (MP tray) on page 1-13.
