Troubleshooting

Improving the print quality

If you have a print quality problem, print a test page first (see Machine Info. on page 71). 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 use the 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 properly.
