You can specify the reproduction ratio in increments of 1%.
The reproduction ratios you can specify are 25 400%. However, if the originals are placed in the ADF, the maximum reproduction ratio is 200%. To copy originals at a reproduction ratio above 200%, you must place them on the exposure glass.
You can select a ratio regardless of the size of an original or copy paper. With some ratios, parts of the image might not be copied or margins will appear on copies.
