PAPER ADV Switch

Momentarily press this switch to advance the paper one line, or press and hold the switch to advance to
the top–of–form of the next page. This switch can be configured to advance the paper only after print-
ing any data remaining in the buffer, or to move paper without printing. (Refer to the Configuration
chapter.) When the printer is on line, press the PAPER ADV switch to advance to the next top–of–
form. However, if there is any data in the buffer, no paper motion occurs and the message ON LINE
DATA IN BUFFER momentarily displays.
NOTE: If the Paper Advance Switch is configured for Move Paper Only and data from the
host does not end in a paper motion command, the last line of text will print on the first line
of the next page.
The PAPER ADV switch is also used to set top–of–form. (Refer to Setting Top–of–Form section on
page 2–12.)

VFU LOADED Indicator

This LED indicator lights when the form (paper) format is being controlled by the Vertical Format
Unit. (Refer to the Configuration and VFU chapters.) When the appropriate VFU is selected by the
operator and loaded by the host computer, this indicator lights.

(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

To make configuration changes, the ENTER switch must be unlocked. When the printer is OFFLINE
READY, simultaneously pressing MENU UP and MENU DOWN alternately locks and unlocks the
ENTER switch. No other switches are affected by this action. Use the MENU UP, MENU DOWN,
NEXT, and PREV switches to display configuration parameter main menus, submenus, and certain
diagnostic tests. After the required menu displays, use the NEXT and PREV switches (shown on the
Control Panel Configuration Diagram in the Configuration chapter) to display individual parameters.
The value shown on the display with an asterisk (*) is the current parameter value retained in printer
memory.
