Possible Cause / Solution
•
Switch on/off the scanner’s power.
•
Software is not to be launched during the initialization time of the scanner (about 30 s).
•
Use the network administration utility
Ping
to test the reachability of the scanner. Call the
Windows <Command Prompt> and execute ping 192.168.42.30 (exemplary IP address)
•
Use the network protocol
Telnet
to provide a bidirectional text-oriented communication to the
scanner by using the scanner specific commands. Call the Windows <Command Prompt> and
execute telnet 192.168.42.30 2727 (exemplary IP address and port).
Note: Telnet is not available on all Windows computers by default!
PC
•
On some computers, the performance of the software can be increased dramatically by switching
off the hardware graphic acceleration:
<Start> <Settings> <Control Panel> <Display> <Settings> <Advanced> <Troubleshooting>
<Hardware acceleration>: None
•
A too high display resolution can cause problems. Test temporarily a setting of 800x600 pixel at
high color (16 bit).
•
For several reasons the PC can be overloaded. This can be checked by running the scanner
software and pushing CTRL+ALT+DEL at the same time. In the task manager a window for the
system performance can be selected. The value must be every time much below 100%.
•
In some cases, the graphic card of the computer can interrupt serial communications for too long
a time. S3-graphic cards are known to exhibit this problem. The only solution is to exchange the
S3-graphic card.
