EXPOSURE ADJUSTMENTS

CHAPTER2 MAKING COPIES 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

30of the Key Operator’s Guide). If pre-scan is enabled, such obscuring may be reduced.
