The page count number is intended to be a permanent record showing the number of pages processed by a particular print engine. The page count is comparable to the odometer in a car showing the distance travelled.
In an effort to prevent misuse, Adobe Systems withheld the publishing of any methods for resetting the page count on PostScript printers using their code. Although there are legitimate reasons for resetting the page count, Adobe and Apple will not publish this information.
In order to properly track the page count for maintenance purposes, it is recommended that you place a sticker inside the printer which notes the date and the page count when the printer was serviced. This will help ensure that the ozone filter and other consumable items are replaced at the recommended intervals.
