Glossary
AppleTalk
AppleTalk, which comes with Apple Computer's Mac OS, is a network protocol. AppleTalk enables file/printer
sharing and also enables you to utilize application software that is on another computer on the same AppleTalk
network.
Auto Form Feed Timeout
During data transmission, the machine may sometimes have to wait until receiving the next data. This is the
auto form feed timeout. When the preset timeout passes, the machine automatically put paper out. However,
no output is performed if the last page has no data to be printed.
Auto-IP
This is a protocol that automatically assigns IP addresses on a TCP/IP network. On a network without a DHCP
server, this can assign IP addresses so that there is no duplication with other devices. IP addresses are
assigned from the range 169.254.0.0 to 169.254.255.255, which is reserved for Auto-IP.
Auto Paper Selection
A function to automatically select paper in the same size as original at printing
Auto Sleep Mode
A mode designed for electrical power saving, activated when the machine is left unused or data transfer for a
specific period. In Sleep mode, power consumption is kept to a minimum.
Bonjour
Bonjour, also known as zero-configuration networking, is a service that automatically detects computers,
devices and services on an IP network. Bonjour, because an industry-standard IP protocol is used, allows
devices to automatically recognize each other without an IP address being specified or DNS server being set.
Bonjour also sends and receives network packets by UDP port 5353. If a firewall is enabled, the user must
check that UDP port 5353 is left open so that Bonjour will run correctly. Some firewalls are set up so as to reject
only certain Bonjour packets. If Bonjour does not run stably, check the firewall settings and ensure that Bonjour
is registered on the exceptions list and that Bonjour packets are accepted. If you install Bonjour on Windows
XP Service Pack 2 or later, the Windows firewall will be set up correctly for Bonjour.
Default Gateway
This indicates the device, such as a computer or router, that serves as the entrance/exit (gateway) for accessing
computers outside the network that you are on, When no specific gateway is designated for a destination IP
address, data is sent to the host designated as the Default Gateway.
DHCP (Dynamic Host Configuration Protocol)
Dynamic Host Configuration Protocol (DHCP) that automatically resolves IP addresses, subnet masks, and
gateway addresses on a TCP/IP network. DHCP minimizes the load of network management employing a large
number of client computers because it relieves individual clients including printers from the IP address being
assigned.
