Color misregistration
Recommendation
 To improve the color density, calibrate the colors using first the control panel
and then the printer driver (see Color Calibration on page 108).
 To adjust the print position of colors for sharper edges, perform the color
registration using the control panel (see Color Registration on page 109).
 Make sure toner save mode is off in the control panel or the printer driver.
See Toner Save Mode in Advanced tab on page 43 (For Windows
driver), Advanced options on page 60 (For Windows
driver), Advanced print settings on page 75 (For Macintosh printer driver),
Printer Features on page 79 (For Macintosh BR-Script printer driver).
 If the print quality is poor, clear the Improve Gray Color check box of the
printer driver. See Improve Gray Color in Settings dialog box on page 38

(for Windows printer driver), Advanced options on page 60 (for Windows
BR-Script printer driver), Advanced print settings on page 75 (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 38 (for Windows
driver), Advanced options on page 60 (for Windows
driver), Advanced print settings on page 75 (for Macintosh printer driver), or
