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 = (d+e+f)/2 + g+h x 3/2
Number of printed original images: B
= Total counter＋ Number of pages in Single-sided with combine
mode ＋ Number of pages in Duplex with combine mode
B = c+g+h
» c Total counter : SP 8581 001 (pages)
» 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.
