2-5 Operation
HOLD ENABLE, REPRINT PA1, CANCEL PA2, ALT MODE
(Optional Switches)
These four switches and their associated LEDs are included on printers equipped with a
Printronix PI-3287 printer interface and operate independently of all other control panel
switches. The PI-3287 enables a Printronix printer to emulate an IBM 3287 printer; the printer
may then be used with an IBM 3274 or 3276 control unit. Information on the operation and
function of these switches is contained in the PI-3287 User's Reference Manual. If the printer
is not configured to emulate an IBM 3287 printer, these switches are not provided.
THE SWITCHES DESCRIBED BELOW ARE ACCESSED BY
RAISING THE PRINTER COVER:
MENU UP, MENU DOWN, NEXT, and PREV Switches
Pressing MENU UP and MENU DOWN simultaneously (from the OFFLINE READY disĆ
play) will alternately lock and unlock the ENTER switch. No other switches are affected by this
action. The MENU UP, MENU DOWN, NEXT, and PREV switches are also used to display
configuration parameter main menus, submenus, and certain diagnostic tests. After the reĆ
quired menu is displayed, individual parameters are displayed using the NEXT and PREV
switches as shown on the Control Panel Configuration Diagram in the Configuration chapter.
The value shown on the display with an asterisk (*) is the currently active parameter value reĆ
tained in printer memory.
NOTE: When the printer is off line, configuration menus and parameter values may be
viewed at any time, but may only be changed by unlocking and using the ENTER switch.
The ENTER switch loads a displayed value into printer working memory. The ENTER
switch may only be unlocked when the printer is off line; it cannot be unlocked or locked
from within a menu.
RUN/STOP
RUN/STOP performs the following functions:
n Press RUN/STOP simultaneously with CLEAR to reset the printer.
n If a diagnostic test is selected and shown on the display, press RUN/STOP to start
the test and press it again to stop the test.
n If the CONFIGURATION PRINTOUT message is selected and shown on the disĆ
play, press RUN/STOP to print a list of the current configuration.
ENTER
Press ENTER to enter a displayed parameter value into printer working memory. The previĆ
ous value is replaced by the displayed value. The ENTER switch must be used to alter a menu
selection and those parameters displayed using the PRINT MODE and F/L switches. FuncĆ
tions activated by the RUN/STOP and 6/8 LPI switches do not use the ENTER switch.
