NTP
Network Time Protocol (NTP) is used to synchronize the internal clocks of computers over a network
connection at system startup and every subsequent 24-hour period thereafter. This feature ensures
that the printer’s internal clock stays synchronized with the NTP server you specify. If the printer is
configured to use DHCP and an NTP server, or if the Greenwich Mean Time (GMT) offset is provided by
the DHCP server, then data entered on this page is overwritten by the corresponding parameters
retrieved from the DHCP server.
CAUTION: Enabling NTP or modifying NTP settings causes the printer to restart.
Note: If your printer is locked, you must log in as a system administrator. For details, see Accessing
CentreWare IS on page 17.
