Typical Programming Errors and Solutions
This section lists several concrete examples of programming errors,
their causes, and sample solutions to these problems.
Problem:
The scanner does not scan correctly when a scanner with a
different maximum scannable area is connected.
Cause
You relied on the default maximum scannable area
setting instead of setting the scanning area with the
ESC A command. The maximum scannable area
differs by scanner model.
Solution
Always set the scanning area with the ESC A
command.
Use the ESC I command to determine the current
scanner’s maximum scannable area, and make sure
the parameters in the ESC A command do not
exceed those values.
