Problem:

When connecting a different scanner model, a

time-out occurs on your computer and you can no longer scan.

Cause

The time required for the initialization process and for the preparation time when you send an ESC G command differs by scanner model. The new scanner model took longer than the previous scanner.

Solution

Make sure you provide enough time on your time-out clock to handle all scanner models (35 seconds should be enough).

Problem:

When writing data from a GT-6000 or GT-4000 to a magneto-optical disk, an interface error occurs on the scanner.

Cause

On the GT-6000/4000, the scanner produces an interface error if no handshake response is received within 30 seconds. If a writing operation takes longer than 30 seconds, this error occurs.

Solution

Adjust the size of your data buffer so that no writing operation takes longer than 30 seconds.

Here are some additional items to consider when you write a scanner program.
