Getting to know the 8825/8830 DDS
The Scanner
The Scanner unit contains a DDS User Interface and display, plus two other
operator-accessible controls: the Power On/ Off Switch and the
Forward/Reverse Switch. The Power On/ Off Switch applies and removes
AC power to the Scanner. The Forward/Reverse Switch is used mainly to
remove documents from the Scanner's feed mechanism. There are no user
serviceable parts inside the scanner.
The 7346/7356 Scanner can scan images at the speeds shown in the table
below:

Sophisticated software and hardware in the Scanner and the associated
Controller allow enlargement and reduction of the captured image and
corrections for several types of defects in original documents. All these
functions are controlled from the DDS User Interface on the Scanner.
The DDS User Interface, physically mounted on the Scanner, receives all
power and information from the Controller on the right side of the Printer.
