The scanner function level
The available resolutions
The maximum scannable area
The basic format of this data is as follows:
The first two bytes show the scanner function level, in ASCII character format. The scanner function level tells you which commands are supported by the attached scanner.
Following these two bytes are the available scanner resolutions, described in 3-byte groups. Multiple resolutions are listed, and the available resolutions differ according to scanner model. The values listed are the available values for the parameter in the ESC R (Set resolution) command. The values listed can be assigned to both the main scan and sub scan; the main scan and sub scan can be set independently of one another. The final 5 bytes are the maximum scannable area when the maximum resolution and 100% zoom are selected. This value also varies by scanner model. This value, along with the maximum resolution value, are the maximum parameters available with the ESC A command.
