The instruction takes the form of an Enable command. When the Enable command is received, if there is a
document on the scanner it will be read, otherwise the scanner will read the next document that is placed on the
scanner.
There is also a Disable command, which can be used to cancel the Enable command.
Another way to look at these modes is that if Enabled the scanner will asynchronously read a document and
send data whilst in Disabled mode the client application can implement a polled or prompted document read.
Sleep Mode
Sleep mode is a deeper version of disabled. When in disabled mode the scanner can still detect documents
however in sleep mode this detection is switched off. The scanner is essentially not doing anything except
responding to commands and therefore consumes minimal CPU resources and electrical power.
Suspended Mode
Suspended mode is like Sleep mode but in addition to turning off document detect it also disables the RFID
interface. This mode consumes even less CPU resources and electrical power.
Auto Disable Mode
The scanner can be set up to auto disable after it has read a document. In this mode an Enable command must
be sent to the scanner every time a document is to be read. This gives precise control over when the scanner is
able to read a document and is suitable for applications such as Self Service Kiosks. The Disable command can
also be sent to cancel an Enable if a document is not read in the mean time.
Normal Read Mode
The scanner will read any document that is placed on the glass. In this mode the scanner does not get disabled
when a document is read. The Disable command can be sent to stop the scanner from reading if required at
any stage, the Enable command will clear the disable.
In any mode it is possible to start the scanner either enabled, disabled, sleep or suspended.
These modes are best controlled via the API and it can be demonstrated in both the 3M
TM
Page Reader Expo
and the High Level Test Container.
If the application is restarted or the scanner power is recycled then the mode will default to the startup mode.
The startup and auto disable mode is specified in the file #Reader.ini.
