Basic operation

All high-level digital sender processes are routed through the formatter, which processes images and communicates with other devices.

The basic digital sender operation can be divided into three systems:

The engine control system, which includes the power supply and the scanner controller board

The pickup-and-feed system, which consists of various rollers and transports the media through the ADF

The scanner system, which scans documents and sends them to the formatter in the form of data

Sequence of operation (scanner)

Period (sequence)

Description

 

 

Power on

The period of time from when the digital sender power is turned on until the main motor begins

 

to rotate.

 

 

Initialization

The period of time after the initial power-on sequence and before the digital sender is ready

 

to scan. During this time, the scanner and ADF initialization is completed, scanner calibration

 

is performed, and the ADF checks for media in the input tray.

 

 

Standby

The period of time from the end of the initialization sequence until a request for a scan. During

 

this time, the scan carriage is in the Home position and the digital sender might go into Sleep

 

mode.

 

 

Scan

The period of time immediately following a request for a scan. The scanner fan turns on, the

 

scan start position is adjusted, the digital sender performs the scan, and data is sent to the

 

formatter.
