Original Type Selection - Canon MF7280 - ImageCLASS B/W Laser Copying Manual

Original Type Selection

The machine is capable of processing and producing copies according to the type
of the original. You can manually select the original type so that the machine
reproduces copies as faithful as possible to the original. The following three original
type modes are available for adjusting the image quality.

• Combinations of these three modes (Text, Text/Photo, and Photo) cannot be selected at
the same time. If you select one of these modes, the previously set mode is canceled.
• If you make copies of an original containing halftones, such as a printed photograph,
using the Photo mode, the moiré effect (a shimmering, wavy pattern) may occur. In this
case, you can lessen the moiré effect by using the Sharpness mode. (See "Adjusting the
Contrast (Sharpness)," on p. 3-26.)
NOTE
• The default setting is 'Text'.
• If you select the Automatic Exposure Adjustment mode, the original type mode is grayed
out and fixed to Text mode. If you select the Text/Photo or Photo mode, the exposure can
only be adjusted manually.
If the original is a transparency, select the original type ➞ adjust the exposure to the most
•
appropriate level for the original.
■ Text Mode
This mode is best suited for making copies of text originals. Blueprints or pencil drawn
originals can also be copied clearly.
■ Text/Photo Mode
This mode is best suited for making copies of originals containing both text and images/
photos, such as magazines or catalogues.
■ Photo Mode
This mode is best suited for making copies from photos printed on photographic paper, or
making copies of images printed with halftone dots (i.e., printed photos).
