2–5Operation
ON LINE Switch
Press
this switch to place the printer alternately on line or of
f line. When
the printer is on line, the ON
LINE
LED lights. The printer must be on line to receive data from the host computer
. When the printer
is
on line, the display indicates the current print mode, and only the
P
APER ADV control panel switch
functions.
When the printer is of
f line, the display reads OFFLINE READY
. All switches are active
(except
the ENTER switch unless it has been unlocked), and the printer cannot communicate with
the
host
computer
. The printer must be of
f line to change printing format or configuration and goes of
f line
automatically if a fault occurs.
If the display shows
OFFLINE HEX DUMP (a diagnostic selection), pressing the ON LINE switch
causes
the printer to go on line, and data from the host computer is printed in “hex dump” format. The
display
shows ON LINE HEX DUMP
. Pressing the ON LINE switch
again takes the printer back to the
OFFLINE
HEX DUMP state.
CLEAR Switch and CHECK Indicator
If
a fault condition occurs, a fault message appears on the Message
Display
, and the CHECK indicator
flashes
alternately with the ON LINE indicator
. After you correct the fault condition, press the
CLEAR
switch.
The fault
status will be validated and the display updated. If all faults were corrected, the dis
-
play will indicate the printer is off line.
In
addition,
the CLEAR switch has the special functions noted below
. Except when used to reset the
printer (#1 below), the CLEAR switch operates only when the printer is off line.
1. Simultaneously pressing CLEAR and R/S (RUN/STOP) resets the printer. You may reset the
printer
at any time, on line, of
f line, or while printing. However
, it is recommended that you reset
the printer only when it is off line and no data is in the buffer, or loss of data may result.
2. CLEAR
is used with the P
APER ADV switch to set top–of–form. (Refer to Setting the T
op–of–
Form
section on page 2–12.)
3. Pressing
CLEAR when one of the configuration parameter values is displayed places the printer
back to of
f line status. Refer
to the Control Panel Configuration Diagram in the Configuration
chapter.
4. Pressing CLEAR silences the audio alarm during a fault condition.
6/8 LPI Switch
Press
this switch to display the current line spacing in lines per inch (lpi). Subsequently pressing this
switch

selection through 6, 8 and 10.3 (7/72”) lpi. Use of the ENTER switch is not required to
select the line spacing. The LED next to this switch lights when line spacing is
other

LPI switch functions only when the printer is off line.
