Troubleshooting
Improving the print quality
If you have a print quality problem, print a test page first (Menu, 3, 2, 3). If the printout looks good, the problem is probably not the machine. Check the interface cable connections or 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 the recommended paper. Check that you use paper that meets our specifications. (See Acceptable paper and other print media
on page 20.)
b Check that the drum unit and toner cartridges are installed properly.
