This copier has seven exposure modes to choose from: AUTO, TEXT/PRTD. PHOTO, TEXT/PHOTO, TEXT,
PHOTO, PRINTED PHOTO and MAP.
[AUTO]
This is the standard initial setting for this copier. When a black and white copy is made, the exposure is automatically
adjusted to obtain the best image quality. When a full-colour copy is made, the image is adjusted in the same way
as when [TEXT/PRTD.PHOTO] (initial settings) is selected.
[TEXT/PRTD. PHOTO, TEXT/PHOTO, TEXT, PHOTO, PRINTED PHOTO and MAP.]
The exposure can be manually adjusted in 9 steps.

Example: 
The [TEXT/PRTD.PHOTO]
key is selected
