To provide full scale (1x1 or magnified (2x1 imaging and continuous tone image scanning in an Image Input Terminal, a variable slow scan speed capability is required in order to operate within system data rate limitations. The variable scan speed should preferably be available in both a first scanning mode where the document rests on the platen while being scanned and in a second scanning mode where the document is advanced across a scan slit by the Controlled Velocity Transport (CVT) of an Automatic Document Feeder (ADF).
