Improving the print quality

If you have a print quality problem, print a test page first (

, All Settings, Printer, Print

Options, Test Print). If the printout looks good, the problem is probably not the machine.

Check the interface cable connections and try printing a different document. If the printout or test
page printed from the machine 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.

To get the best print quality, we suggest using recommended paper. Make sure you use
paper that meets our specifications (see Acceptable paper and other print media
on page 34).

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
document.

Colored letters and thin characters

in the original document are light or

faint in the copy



Choose Text or Receipt in the copy quality setting
(see Advanced User's Guide).



Adjust the copy density and contrast (see Advanced User's
Guide).
