Recommendation
 If coloured lines appear at 30 mm intervals, identify the colour
causing the problem and replace the toner cartridge that
matches the colour of the line (see Replacing the toner
cartridges on page 84).
To identify the colour of the toner cartridge, visit
http://solutions.brother.com/ to view our FAQs and
troubleshooting tips.
 If coloured lines appear at 94 mm intervals, put a new drum
unit (see Replacing the drum unit on page 89).
 Make sure the media type setting in the driver matches the
type of paper you are using (see Acceptable paper and other
print media on page 33).
 Check the machine's environment. Conditions such as high
humidity can cause hollow print
(see Product Safety Guide).
 If the problem is not solved after printing a few pages, foreign
material, such as glue from a label, may be stuck on the drum
surface (see Cleaning the drum unit on page 117).
 Put in a new drum unit (see Replacing the drum unit
on page 89).
 Identify the colour causing the problem and put in a new toner
cartridge (see Replacing the toner cartridges on page 84).
