To check the paper consumption, look at the total counter and the duplex counter.
The total counter counts all pages printed.
• For one duplex page, the total counter goes up by 2.
• For a duplex job of a three-page original, the total counter goes up by 3.
The duplex counter counts pages that have images on both sides.
• For one duplex page, the duplex counter goes up by 1.
• For a duplex job of a three-page original, the duplex counter will only increase by 1, even though
two sheets are used.
Recommendation
Please explain these features to the customers so they can reduce their paper usage.
