Error code:
E270 (Error in the main scanning/sub scanning synchronization signal)
-0101 Sub scanning synchronization signal (VSYNC) is not properly transmitted from Scanner
Unit PCB (back side scanner unit), and this causes image failure or abnormal termination.
E280 (Communication error between reader controller PCB – scanner unit)
- 0101 If the communication is not started within the specified time between reader controller
PCB – back side scanner unit.
E400 (Communication error between reader controller PCB – DADF)
-0001 If check sum error occurs during communication between reader controller PCB - DADF.
-0002 If reception error occurs during communication between reader controller PCB - DADF.
E490 (Error caused by incorrect DADF type)
-0001 If a not-supported DADF type is installed.

scanning
Original is picked up
and the front surface
is scanned by the
scanner unit in reader
side while back
surface is scanned
by the scanner unit in
DADF side.
And then, it is
delivered.
