Improving the print quality B If you have a print quality problem, print a test page first (Menu, 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. 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 uu page 20.) b Check that the drum unit and toner cartridge are installed correctly. Examples of poor print quality ABCDEFGH abcdefghijk ABCD abcde 01234 Faint Recommendation  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.  If the LCD shows Replace Toner, put in a new toner cartridge. See Replacing the toner cartridge uu page 67.  Check the machine's environment. Conditions such as humidity, high temperatures, and so on, may cause this print fault. See Product Safety Guide: Choosing a location.  If the whole page is too light, Toner Save may be turned on. Turn off Toner Save in the machine's menu settings or Toner Save Mode in the Printer Properties of the driver. See Advanced User's Guide: Toner Save. See Software User's Guide: Printing (for Windows®). See Software User's Guide: Printing and Faxing (for Macintosh).  Clean the corona wire of the drum unit. See Cleaning the corona wire uu page 73.  Put in a new toner cartridge. See Replacing the toner cartridge uu page 67.  Put in a new drum unit. See Replacing the drum unit uu page 75. 116
