When toner saving in text mode is selected in the image adjustment sub-menu (08)
of the user tools menu, an 8 x 8 matrix filter reduces the number of black dots in
the image. As a result, less toner is used to create the latent image on the drum.
Printer Gamma (γ γ ) Correction
Printer correction corrects the data output from the IPU to the laser diode to
account for the characteristics of the printer (e.g., the characteristics of the drum,
laser diode, and lenses).
The machine chooses the most suitable gamma curve for the original type selected
by the user. There is no SP adjustment for this.
