POWER ON, WHEN LIGHTING LAMP.
GREEN LED
INDICATOR “ON-LINE”
l ON LINE (STANDBY PRINTING.)
l LAMP OFF( NOT TO PRINT).
l LED FLASHING, WHEN NO PAPER
FEED S/W
PRESS TO ADVANCE PAPER
2-3. SELF TEST
The self –test mode checks the printers control circuit function, setting parameter,
software version, and printer quality.
① Before running the self -test, make sure there is sufficient paper.
② On pressing FEED S/W(SE7300) , and power ON, starting the self-test.
③ Printer becomes ready to receive data from the host.
2-5. DUMP MODE
Dump mode checks whether printer receives data correctly from the host
or not.
① Before running the self -test, make sure there is sufficient paper.
② On pressing FEED S/W(SE7300), and power ON, starting the self-test.
③ After ending the self-test, continually press FEED S/W (SE7300), Then
print “**[ HEX DUMP PRINT START ]**”
after 2 seconds.
④ Thought you don’t touch any s/w, the printer take out HEXA mode
changed data from host
⑤ If power off, printer “s recovered to normal mode
