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, and then it passes to the
page memory for printing.
