Auxiliary Commands
Auxiliary commands are provided for physical operation of the
scanner. These commands include the reset command and option
operation commands.
1. Initialize the scanner (ESC @)
This command returns all scanner settings to their original values (the
values when the scanner is first turned on). The carriage returns to the
home position. However, the definitions created with the ESC b and
ESC z commands are not erased.
2. Set the scanning mode (ESC g)
You can select from two modes with this command: high-speed mode
and normal mode. The scanner is always in normal mode unless you
change it with this command. If you are scanning at 8 bits/pixel (in
monochrome) or 8 bits/color/pixel (in color) you must select normal
mode.
In high-speed mode, the scanner moves its sensor faster. This is useful
if a high degree of scanning precision is not required, or if you are
scanning bi-level data such as characters or line drawings.
