2.4. Scanner

2.4.1. Purpose

The purpose of the scanner is to provide mechanical transport to convert hardcopy originals to electronic data.

2.4.2. Hardware

The scanner converts the image from hardcopy to electronic data. A document handler moves originals into a
position to be scanned. The scanner provides enough image processing for signal conditioning and formatting. The
scanner does not store scanned images. All other image processing functions are in the copy controller.

2.5. Graphical User Interface (GUI)

The GUI detects soft and hard button actuations, and provides text and graphical prompts to the user. The GUI is
sometimes referred to as the Local UI (LUI) to distinguish it from the WebUI, which is exported by the web service
that runs in theccontroller. Images are not transmitted to or stored in the GUI. The Start hard button is located on
the GUI panel.

or IOT)
2.6.1. Purpose
The Marking Engine performs copy/print paper feeding and transport, image marking and fusing, and document
finishing. Images are not stored at any point in these subsystems.
2.6.2. Hardware
The marking engine is comprised of paper supply trays and feeders, paper transport, LED scanner, xerographics, and
paper output and finishing. The marking engine contains a CPU, BIOS, RAM and Non-Volatile Memory.
