Improving The Print Quality - Brother DCP-L8400CDN Basic User's Manual

Improving the print quality

If you have a print quality problem, print a test page first (
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
Brother does not recommend the use of cartridges other than Brother Original cartridges or the
refilling of used cartridges with toner from other sources.
a
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 28).
b
Check that the drum unit and toner cartridges are installed correctly.
