The number that is displayed is the number of scanned original sheets, not the number of scanned original pages. For example, when 2-sided copying is performed using one original, the number "1" will appear to indicate that one original sheet was scanned, not "2" to indicate the front-side page and the reverse side page.
If the displayed number of original sheets is different from the actual number of sheets
tap the [Cancel] key to stop the job.

Tap the [OK] key to start copying.
If this function is combined with [Job Build], the count result is displayed after the [Print Start] key has been tapped.
