Automatic
This is the standard initial setting for this copier. In this mode, the
characteristics of an original being copied are “read” by the exposure
system, and exposure adjustments are made automatically.
This optimizes the contrast of the copied images.
Original image type
TEXT/PRTD. PHOTO:
This mode provides the best balance for copying
an original which contains both text and printed
photographs.
TEXT: This mode is useful in enhancing very low density
areas of an original or in suppressing unusually
high-density background areas.
TEXT/PHOTO: This mode provides the best balance for copying
an original which contains both text and
photographs.
PRINTED PHOTO: This mode is useful for copying printed
photographs.
PHOTO: This mode provides the best copies of photographs
with fine details.
MAP: This mode is useful to provide the best shading
and fine details found on most maps.
COPY OF COPY: This mode provides the best result for originals
such as copied text or copied photos. If the check
box is checked, only Text/prtd. photo, Text and
Printed photo mode keys will be shown on the
touch panel and the exposure can only be adjusted
manually.
EXPOSURE ADJUSTMENTS
Exposure selections for this copier should be selected according to
the type of originals being copied: TEXT/PRTD. PHOTO, TEXT,
TEXT/PHOTO, PHOTO, PRINTED PHOTO or MAP. (Refer to the
samples on page 4 to see the effects on copy images in relation to
the EXPOSURE ADJUSTMENTS.) If the original image type is
TEXT/PRTD. PHOTO, TEXT or TEXT/PHOTO, the exposure can be
adjusted automatically or manually. If the original image type is
PHOTO, PRINTED PHOTO or MAP, the exposure can be adjusted
manually only. If the COPY OF COPY mode is selected only TEXT/
PRTD. PHOTO, TEXT, or PRINTED PHOTO exposure can be
selected and these can only be manually adjusted. If the COLOR
TONE ENHANCEMENT mode is selected, color copies will be more
vivid. The standard initial setting of the original image type for this
copier is TEXT/PRTD. PHOTO.
When copying a colored original in the Black/White copy mode, a
colored background with text in the background area may be
copied with the text obscured. Check with the key operator for the
setting of “Disabling of Pre-scan in B/W Copy” program (see page
30 of the Key Operator’s Guide). If pre-scan is enabled, such
obscuring may be reduced.
