Recommendation
 Make sure Toner Save mode is off in the control panel of the machine
or the printer driver.
 Perform the calibration. (See Calibration on page 77.)
 Adjust the colour by using the custom setting in the printer driver and
by using the control panel of the machine. Colours the machine can
print and colours you see on a monitor are different. The machine
may not be able to reproduce the colours on your monitor.
 If colours appear in the printed grey areas, make sure there is a check
in the Improve Grey Colour check box of the printer driver. (See
Basic tab for Windows
printer driver or Features for Macintosh BR-Script printer driver in the
Software User's Guide.)
 If shaded areas look dull, remove the check from the
Improve Grey Colour check box.
 If a printed black graphic is too light, choose
Enhance Black Printing mode in the printer driver. (See Settings
®
Dialog for Windows
BR-Script printer driver, Print Settings for Macintosh printer driver or

cartridge. (See Replacing a Toner cartridge on page 35.)
