Improving the print quality B
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 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
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
uu page 19.)
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.
uu Replacing the toner cartridge uu page 41
 Check the machine’s environment. Conditions such as humidity, high
temperatures, and so on, may cause this print fault.
uu Product Safety Guide: Choose a safe location for your product
 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.
