[ 0 to 100.00 / - / 0.01 %/step ]
This SP mode displays the “coverage ratio” of the
output, i.e. the ratio of the total pixel area of the
image data to the total printable area on the
paper. Note that this value is not directly
proportional to the amount of toner consumed,
although of course it is one factor that affects this
amount. The other major factors involved include:
the type, total image area and image density of
the original, toner concentration and developer
potential.

SP 7-833-5 to -8 vs SP 7-908-1 to –4
The averages for K (SP 7-833-5 and SP 7-908-1)
are the same.
For CMY, SP 7-908 does not include black-and-
white pages in the middle of a colour job.
However, SP 7-833 does include these pages in
the average. As a result, the readings of SP 7-833
will be lower, because these averages include
pages for which there is zero for CMY, but the
averages calculated for SP 7-908 do not include
these pages.
