Displays the value given by the following formula:
(Current printouts ÷ Target printouts) × 100. This shows how much of the
unit's expected lifetime has been used up.
The Page% counter is based on printouts, not revolutions. If the number of
printouts reaches the limit, the machine enters the end condition for that unit.
If the revolution count lifetime is reached first, the machine also enters the
end condition, even though the Page% counter is still less than 100%.
