Troubleshooting
Improving the print quality
If you have a print quality problem, print a test page first (see Print a test page uu page 82). 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
Brother does not recommend the use of cartridges other than genuine 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 are using paper that meets our specifications. (See Acceptable paper and other print media uu page 2.)
b Check that the drum unit and toner cartridge are installed correctly. | 6 | |
