3 SCANNER COMPONENTS AND FUNCTIONS
The SCAMAX 2600/4000 scanner consists of the following main elements:
The paper transport system – it pulls sheets of paper into the scanner, transports them through the
machine and deposits them in the output hopper. It consists of input hopper, which is adjustable for single
sheet feed or stack feed, paper separation unit, transport mechanism and output hopper.
The illumination unit.
The optical system consisting of two mirrors plus a lens with colour filter.
The scan module 1, scanning the front of each document, is present in all SCAMAX scanners.
The scan module 2, scanning the back of each document, is only found in duplex models.
The controller board – controls all process in the machine.
The I/O board – converts TTL signals from the controller board into the signals required by the various
‚users’, such as motors. It also converts outputs from sensors, such as photocells and switches, into TTL
signals.
The operator panel – facilitates basic operation of the scanner, except for scan commands and internal
settings.
The power supply unit – supplies the necessary voltages for the entire machine.
The ultrasound double feed detector.
Optionally fitted elements are:
One DTplus board for each scan module, which significantly enhance images from difficult documents.
The greyscale interface.
