3. A user always connects the MFP Server.
Contact with the current user and ask the user to disconnect
the device.
If the user forgets to disconnect the device, you can inform
the administrator to release the device.
4. I can't use the MFP to scan, print, read the card reader or fax a
file even I have followed the installation of MFP as the manual.
Check if the MFP you are using is in the "Compatibility List"
in Appendix.
Attached the MFP to PC directly and try if the MFP is able to
use.
5. My computer has installed the firewall and the MFP Server can't
work normally in my computer.
Some firewalls, for example, the "Network Access Manager"
firewall program attached with nVidia network card may
block the communication between MFP Server and your
computer; you have to add the MFP Server programs to the
exception list of your firewall. The programs are as follows.
1. Add "servoap.exe" program to the exception list.
2. Add "mfpagent.exe" program to the exception list.
