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 and follow the
recommendations in the table.

IMPORTANT

Using non-genuine 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. See

2. Check that the toner cartridge and drum unit assemblies are installed correctly.
