U470 Setting the JPEG compression ratio
Description
Sets the compression ratio for JPEG images in each image quality mode.
Purpose
To change the setting in accordance with the image that the user is copying. For example, in
order to soften the coarseness of the image when making copies at over 200% magnification,
change the level of compression by raising the value. Lowering the value will increase the com-
pression and thereby lower the image quality; Raising the value will increase image quality but
lower the image processing speed.
