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 disF 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 reF 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 reF 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:

nPress RUN/STOP simultaneously with CLEAR to reset the printer.

nIf 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.

nIf the CONFIGURATION PRINTOUT message is selected and shown on the disF 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 previF 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. FuncF tions activated by the RUN/STOP and 6/8 LPI switches do not use the ENTER switch.
