The IP address of the computer that submits the profile is provided to the printer. The submitting computer then opens a network port and listens for incoming connections from the printer. The computer starts with network port tcp:9751 and progresses to tcp:9752 and so on until it finds an open port. When the printer starts scanning, it tries to open a network connection back to the submitting computer. The submitting computer cannot establish a connection or cancels the scan job if it has a firewall enabled, did not accept the device certificate authentication, or canceled the scan profile login process.
To determine how to disable or enable your firewall, see the documentation that came with your operating system.
For most Linux distributions, you can open specific ports with the iptables command. For example, type
from the command line.If there was an error verifying a security certificate before completing a scan, you need to accept the certificate to proceed with the scanning. You may accept the certificate for a single scan attempt or for all future scan attempts.
If a
is received when attempting to send a scan profile to the device, you need to enter a valid user name and password combination. You may enter the valid user name and password combination for a single operation or for all future operations.
