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 Paper Selection
A function to automatically select paper in the same size as original at printing
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.
dpi (dots per inch)
A unit for resolution, representing the number of dots printed per inch (25.4 mm).
EcoPrint Mode
A printing mode that helps save toner. Copies made in this mode are thus lighter than normal.
Emulation
The function to interpret and execute other printers' page description languages.
FTP (File Transfer Protocol)
A protocol to transfer files on the TCP/IP network, whether the Internet or an intranet. Along with HTTP and SMTP/
POP, FTP is now frequently used on the Internet.
Grayscale
A computer color expression. Displayed images of this sort are typically composed of shades of gray, varying from
black at the weakest intensity to white at the strongest, without any other colors. Gray levels are displayed in
numerical levels: that is, white and black only for 1 bit; 256 gray levels (including white and black) for 8 bits; and 65,536
gray levels for 16 bits.
