Colour misregistration
Recommendation
 To improve the colour density, calibrate the colours using first the control
panel and then the printer driver (see Colour Calibration on page 111).
 To adjust the print position of colours for sharper edges, perform the colour
registration using the control panel (see Colour Registration on page 112).
 Make sure toner save mode is off in the control panel or the printer driver.
See Toner Save Mode in Advanced tab on page 41 (For Windows
driver), Advanced options on page 58 (For Windows
driver), Advanced print settings on page 73 (For Macintosh printer driver),
Printer Features on page 77 (For Macintosh BR-Script printer driver).
 If the print quality is poor, clear the Improve Grey Colour check box of the
printer driver. See Improve Grey Colour in Settings dialog box on page 36

(for Windows printer driver), Advanced options on page 58 (for Windows
BR-Script printer driver), Advanced print settings on page 73 (for Macintosh

If the print quality of the black portion is not what you expected, select the
Enhance Black Printing check box of the printer driver. See Enhance
Black Printing in Settings dialog box on page 36 (for Windows
driver), Advanced options on page 58 (for Windows
driver), Advanced print settings on page 73 (for Macintosh printer driver), or

(see Replacing the toner cartridges on page 123). To identify the colour of
the toner cartridge, visit http://solutions.brother.com/ to view our FAQs and
