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 printers 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.

tray on page 1-10.
■Check the paper type and quality. See What kind of paper can I use? on

cause paper to curl. See What kind of paper can I use? on page 1-5.
■If you dont 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.
