Use case steps:

1. User starts scan request from TWAIN-enabled application.

2. Scan settings can be predefined through TWAIN manager console (if silent mode has been set), OR each

time a scan job is launched, using the driver UI (if interactive mode has been set up on TWAIN manager

console).

3. Once the scan job arrives at the device, it remains queued.

4. Later, the user walks up to the device, places originals, and selects scan job using the device control

panel.

5. Scanning process is performed and scanned images sent to the business application.

6. User picks up originals and returns to work station.

Advantages of running TWAIN on queued scan mode:

●

User only needs to walk up to the device one time.

●

No device reservation is required, jobs are queued.

●

Multiple users sharing one device for scanning purposes (branch office business model).

3.5 Direct Scan mode

This is the classic TWAIN use mode, typically seen in scenarios with flatbed scanners in place. With Direct

Scan mode, the scan process is automatically started in the device after submitting a scan request without

requiring any user interaction.

Direct Scan mode triggers the scan action immediately. The scan action is made after TWAIN client demands

the job (without queuing any job on the device). To activate Direct Scan mode, Admin rights are required. Edit

file %windir%\mfp_hp.config and set tag SILENT_MODE=true. Direct Scan mode will only work if device front

panel is pointing to Home. A job will be rejected if the front panel is not displaying the Home page.
