3.2.6. Broken Link Detection
TCP/IP communications on this product informs the operator when printing is not possible. Therefore, it supports the broken link
detection feature.
There are two broken links that can be detected.
1 Physical link down
Indicates either of the following states.
• Time from powering on the printer until the Ethernet link is established (TCP/IP startup)
• Error status because Ethernet link detected to be down because the LAN cable was disconnected between the printer and
HUB.
Chattering removal conditions when connecting and disconnecting the LAN cable are shown below.
• When LAN cable is disconnected (link down judgment): 4 seconds
• When LAN cable is inserted (link established judgment): 2 seconds
2 IP address lost
Indicates either of the following states.
• Time from TCP/IP startup until IP address is obtained.
• Error status when failed to get IP address.
When a broken link is detected, the following operations are requested to the printer.
IP address lost takes priority over physical link down.
Also, actual operations for LED display and printing warnings must be supported by the printer.
(Fordetails,seesection5.2PrinterFirmwareSupportTableandeachprinter’sproductspecicationsmanual.)
When this happens, check the LAN cable connection and the IP address settings for the communication path, and then restart
the printer.
• LED Display
LED blinking on the printer operation panel inform the operator of the physical link down and IP address lost.
However,theLEDtypeandblinkingcyclesdependontheprinter’sspecications.
Example display on TSP700II/TSP800II
(1) Physical link down
POWER LED (green) and ERROR LED (orange) blink slowly (on=2 seconds, off = 2 seconds).
(2) IP address lost
POWER LED (green) and ERROR LED (orange) blink quickly (on=0.125 seconds, off = 0.125 seconds).
Network communications are ready when both (1) and (2) are removed (blinking stops).
You cannot invalidate this operation.
• Warning print
When physical link down or IP address lost (error when it fails to get the IP address) is detected, this sends warning print data to
the printer to inform the operator that a problem has occurred.
Reception data before and after this operation executes is not guaranteed.
This feature can be made valid or invalid using HTTP (Web), Telnet, and FTP. Use HTTP (Web) to register the warning print
data. The setting is stored on the product’s non-volatile memory.
