Epson 420i - Manual (Page 11)

Settings 1 to 9 have priority over the software designation. Software selection will be
ignored after setting this switch to
1~ 9. If the switch selection is altered during prin-
ting, it will become effective after the current print command is executed.
8. RESET Switch
When this switch is pressed, the printer enters the reset state. When released, the ini-
tialization operation is performed once again, This puts the printer in the same condi-
tion as at power-on.
9. POWER Lamp (Green)
Lights up when power is on. Blinks if an error has been generated.
10. ON-LINE Lamp (Green)
Data can be input when the printer is the ON-LINE state. The ON-LINE lamp is lit when
the printer is ON-LINE, off when the printer is OFF-LINE. When the printer is OFF-
LINE, a BUSY signal is output by the printer.
11. P. EMPTY Lamp (Red)
When a paper-empty signal is detected, the P.E. indicator lights and the buzzer sounds
for 3 seconds. At this time, the printer goes OFF-LINE, and the BUSY and P. EMP
signals are output. If paper-empty is detected during printing, operation is terminated
at completion of the line in which the signal is received.
If the ON-LINE switch is pressed after paper is inserted, the P. EMP state is terminated.
If the ON-LINE switch is pressed without new paper inserted, a single line is printed
(during printing the ON-LINE lamp is lit) and the OFF-LINE state is entered again. This
operation can be repeated as many times as desired.
