Improve the Print Quality
If you have a print quality problem, print a test page first. 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 examples of poor print quality in the table and
follow the recommendations.
IMPORTANT
Using non-Brother supplies may affect the print quality, hardware performance, and machine reliability.
1. To get the best print quality, we suggest using recommended print media. Make sure you use paper that
meets our specifications.
2. Check that the toner cartridge and drum unit are installed correctly.
