Troubleshooting

Improving the print quality

If you have a print quality problem, print a test page first (MENU, Printer, Print Options, Test Print). 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

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 paper that meets our specifications. (See Acceptable paper and other print media

on page 21.)

b Check that the drum unit and toner cartridges are installed properly.
