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 compres-
sion by raising the value. Lowering the value will increase the compression and thereby lower the image qual-
ity; Raising the value will increase image quality but lower the image processing speed.
