
ADF Cable. The relay connector has been discarded to prevent noise.

Exposure Unit. The exposure lamp has been upgraded. The 3-beam APS sensors have
been replaced with a 2-beam + 1-beam configuration. The exposure unit is spot welded (two
screws have been eliminated).

Web Motor Lock Detection. Three new SC codes (SC540-02, -03, -04) have been added to
detect web motor lock.

Development unit. The color of the pressure release filter has been changed from white to
gray.

Paper Feed. Paper feed has been upgraded. There is no change in the removal or
replacement of the paper feed units.

Controller. The GW controller has been upgraded to the GW+ Controller.

MFP Options. DOS (Data Overwrite Security), Data Encryption, and Scan-to-Media are now
provided as standard.

USB/SD Slots. A USB slot and SD card slot is provided on the right side of the operation
panel. Installation of a device for these slots is no longer required.

Safe Shutdown. After the main power switch of the machine has been turned off, the
machine will not shut down immediately. A message states that shutting down may require up
to two minutes to complete. The SDB (a new board) keeps the power supply to the controller
until the HDD unit has been shutdown safely. When shutting down from normal stand-by
mode, if the safe shutdown takes more than 2 minutes, there is a problem with the controller
board and it may need to be replaced.

Fax Unit. The MBU and FCU are combined on one board. After replacing the FCU, the
SRAM data from the old FCU must be transferred to the new FCU. The following data are
transferred: TTI, RTI, CSI, bit switch settings, RAM address settings, and NCU parameter
settings. For more, see the fax installation manual.
