1.5.3. Copying
Single copy
The scanned data passes to the page memory after video processing in the
DIP block. After a page of data has been stored in the page memory, the data
is sent to the LDDR through the LIF block.
Multi-page copy
The scanned data passes to the SAF memory after video processing (DIP)
and compression (DCR). After a page of data has been stored in the SAF
memory, the data passes to the DCR block again for decompression, then it
passes to the page memory for printing.
