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.

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.    
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.

■

Check the paper type and quality. See What kind of 
paper can I use? in Chapter 1.

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? 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

■

Make sure the paper is loaded properly. See Printing 
from the Paper tray in Chapter 1.

■

Check the paper type and quality. See What kind of 
paper can I use? in Chapter 1.

■

Turn over the stack of paper in the tray or try rotating 
the paper 180° in the input tray.

Poor fixing

■

Make sure that the blue tabs in the rear cover are 
re-set by either closing the rear cover or pushing the 
blue tabs to their original position. See Printing on 
envelopes in Chapter 1.
