Improving the print quality
6
If you have a print quality problem, print a test page first (see Machine Information on page 91). If the printout
looks good, the problem is probably not the machine. Check the interface cable or try the machine on another
computer. If the printout has a quality problem, check the following steps first. And then, if you still have a
print quality problem, check the chart below and follow the recommendations.
NOTE
Using non-Brother supplies may affect the print quality, hardware performance, and machine reliability.
a
To get the best print quality, we suggest using the recommended paper. Check that you are using paper
that meets our specifications (see Acceptable paper and other print media on page 2).
b
Check that the drum unit and toner cartridges are installed correctly.
Examples of poor print quality
Recommendation
Printed pages are compressed,
horizontal stripes appear, or
characters in the top, bottom,
left and right margins are cut off
Adjust the print margins on your application and reprint the job.
Colors are light or faint on the
whole page
Perform the color calibration using the Touchscreen or the printer driver
(see Color Calibration on page 116).
Make sure toner save mode is off in the Touchscreen or the printer driver.
Make sure that the media type setting in the driver matches the type of paper
you are using (see Acceptable paper and other print media on page 2).
Shake all four toner cartridges gently.
Wipe the scanner windows with a dry, soft, lint-free cloth. (See Cleaning the
inside of the machine on page 156.)
