3.6 To Use Only the Black Toner to Reproduce Gray Areas

(To use only the black toner to reproduce black-and-white photos or
gradational images)

Before the adjustment

After the adjustment

Using all color toners to reproduce black-and-
white photo images (bitmap data) blends
undesired colors in the image.

Using only the black toner to reproduce black-
and-white photo images can diminish undesired
colors.

Explanation

For printing, only the K toner is usually used to reproduce gray areas of drawing data, lines and text. On the

other hand, all color toners (C, M, Y and K) are used to reproduce gray areas of image data, such as BMP, GIF,

JPEG and TIFF. This provides a deeper gray on the printouts.

The following are examples when image data are reproduced using C, M, Y and K:

• A gray-scale or black-and-white photo is pasted in photo editing software such as Imaging and Paint Shop

Pro, in Internet Explorer, word-processing or spreadsheet software.

• A semi-transparent gray color or gradient of gray is used in the Format AutoShape dialog box on Microsoft

Office.

(The gray area printed out as raster data in the same manner as a photo image is reproduced using C, M and

Y toners, or C, M, Y and K toners.)

Change the option on the printer driver, in order to use only the black toner to reproduce the gray area where C,

M, Y and K are used as described above.

Procedures

* Both the service technician and the user can perform all adjustments.
