mode, sheet originals are fed and scanned by the action of the moving 
originals.In this mode either one side of an original can be scanned or 
both sides of an original can be scanned at the same time. The other 
mode of scanning uses a moving mirror for scanning originals placed on 
the glass platen.

Scanner rack 

AR-RK1

This rack is required to support the scanner module above the printer.

groups of people so that their prints are separated from other users 
making them easy to retrieve.When this unit is installed, any copies or 
facsimile prints will be sent only to the top tray. 

Exit tray 

AR-TE3

Mounted to the paper output port of a duplex module.

This unit is required for the job retention function  to operate.

Multi-function 
controller board 

AR-M11

This print controller is necessary to provide copier, facsimile and network 
scanning capabilities.
