When memory is full

If the amount of data of the scanned originals exceeds the capacity of memory, scanning is interrupted.

Press the [Start] key.
All scanned pages are copied, and data stored in memory are cleared.
Remove the copies, and then continue copying following the instructions on the display.

The number of pages that can be stored in memory is about 5000 pages of A4 (8¹/₂ × 11) size originals. It depends on the type of originals or memory settings.
In Sort mode, you can complete scanning and copying by copying the scanned pages stored in memory until it becomes full, and then scanning and copying the remained originals.
