Improving the print quality

If you have a print quality problem, print a test page first (

All Settings

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.

To get the best print quality, we suggest using recommended paper. Make sure you use
paper that meets our specifications (see Acceptable paper and other print media
on page 28).

Check that the drum units and toner cartridges are installed correctly.
