Improving the print quality

If you have a print quality problem, print a test page first (Menu, 4, 2, 3). 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 17.)

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

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.
