Improving the print quality B
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 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
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
uu page 20.)
b Check that the drum unit and toner cartridge are installed correctly.
Examples of poor print
quality
Recommendation
Faint
Take out the drum unit and toner cartridge assembly. Hold the
assembly level with both hands and gently shake it from side to side
several times to spread the toner evenly inside the cartridge.
If the LCD shows Replace Toner, put in a new toner cartridge.
See Replacing the toner cartridge uu page 67.
Check the machine’s environment. Conditions such as humidity,
high temperatures, and so on, may cause this print fault.
See Product Safety Guide: Choosing a location.
If the whole page is too light, Toner Save may be turned on. Turn
off Toner Save in the machine's menu settings or
Toner Save Mode in the Printer Properties of the driver.
See Advanced User's Guide: Toner Save.
See Software User's Guide: Printing (for Windows
