Chapter 15—Troubleshooting
• Input buffer on host overfl ow.
- The input buffer should normally be handled by the software of the
host. Increase the receive buffer in the printer to a large value, restart
the host to empty its input buffer and try again.
• No response from printer a custom-made program is run (Fingerprint
only).
- The verbosity can be controlled using the Fingerprint instructions
VERBON/VERBOFF and SYSVAR(18). In the Intermec Direct Pro-
tocol, verbosity is disabled by default. Check the program for instruc-
tions that affect the verbosity.
- Verify that the correct communication port is selected as standard
IN/OUT channel.
