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

recommendations in the table.

IMPORTANT

Using non-genuine supplies may affect the print quality, hardware performance, and machine reliability.

To get the best print quality, we suggest using recommended print media. Make sure you use paper that

meets our specifications.

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