Gamma Correction
Gamma correction improves printer output by creating a more grad-
ual change from white to black. However, because some jobs may
benefit from the sharper contrast in uncorrected output, you have the
option of turning off gamma correction. The choices are 0 (gamma
correction is turned off) and 1 (gamma correction is turned on). The
default is 1.
Letterhead
This option appears only if the duplexing unit is installed. Simplex and
duplex jobs normally exit the printer with opposite orientation. The let-
terhead option allows you to print both simplex and duplex jobs with
the same orientation, so letterhead paper can be loaded from the
same tray for either type job and output does not require sorting. If
you are printing in the letterhead mode, letterhead paper must be
loaded face down in the input bins, as shown below. You may notice a
decrease in the printing speed depending on the mix of simplex and
duplex pages. The options are On and Off with Off being the default.
See the chart following “Rotate Duplex” for further information.
