The colour of your printouts is
not what you expected
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 109.)
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, Advanced options for
Windows
®
BR-Script printer driver, Print Settings for Macintosh
printer driver or Printer 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

printer
driver, Advanced options for Windows

cartridge. (See Replacing a Toner cartridge on page 66.)
Put in a new drum unit. (See Replacing the drum unit on page 73.)

Put in a new drum unit. (See Replacing the drum unit on page 73.)
