Command Order
By using the Request ID (ESC I) command, you can determine the scanner model. This allows you to create software that sends only the commands featured on that particular model. Always check the scanner ID before making settings with software commands.
The ID information consists of the following:
❏The scanner function level
❏The available scanner resolutions
❏The maximum scannable area
The maximum resolution and maximum scannable area values are used to determine the available parameters in the Set scanning area (ESC A) command when zoom and resolution are changed.
ID information
1. Scanner function level
The scanner level indicates which commands are supported on the connected scanner, allowing you to make full use of the scanner’s features. You also can determine which commands are not available, so you can avoiding causing command errors.
2. Available resolutions
All scanning resolutions available on the connected scanner are listed in the ID information. All resolutions are available for both the main scan and sub scan; the main scan and sub scan values can be set independently from each other. The last resolution value is the highest resolution available on the scanner.
