3.1 Measuring the Paper Consumed – 3
How to calculate the paper reduction ratio, when compared
with Single-sided copying, with no 2-in-1 combine mode
Paper reduction ratio (%) = Number of sheets reduced: A/Number of
printed original images: B x 100
In the above formula:
Sheet: A sheet of paper
Page: A side of a sheet of paper. In duplex mode, one sheet is two pages
Output page: One side of a sheet of output paper
Original Image: An image of one original page (or, an image of one side of a two-
sided original)
For one sheet of output paper in two-in-one copying, four original pages are
copied onto two output pages.
SP8421-002 and -003 are not used on this product. (They are for MFP machines
only.)
3. Paper Saving
Number of sheets reduced: A
= Output pages in duplex mode/2 + Number of pages in Single-sided
with combine mode + Number of pages in Duplex with combine
mode x 3/2
A = (
