3. Paper Saving
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
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 = (

f
)/2 +
g

h
x 3/2
Number of printed original images: B
= Total counter

d
Single-sided with duplex mode
: SP 8421 001 (pages)
e
Double-sided with duplex mode : SP 8421 002 (pages)
f
Book with with duplex mode
: SP 8421 003 (pages)
g
Single-sided with combine mode : SP 8421 004 (pages)
h
Duplex with combine mode
: SP 8421 005 (pages)
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
¾
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)
¾
For one sheet of output paper in two-in-one copying, four original pages
are copied onto two output pages.
