GP 3.2 Functional Overview

The Control Panel provides the following functions:
• Control of the Print Process
• Recovery from operator intervention conditions
• Modification of system default parameters
• Invocation of various test prints and test modes
The Control Panel provides these capabilities via push-button keys, LED indicators and a menu
system that allows a user to scroll and select values for system parameters and invoke printer
actions independent of the external data system.
3.1 Control Panel Keys
The Control Panel layout is found in section 2. Table 1 summarizes the operation of the Control
Panel keys. Details of the Off-line and On-line states are described in ref. 11.
Table 1 Control Panel Key Usage
Key Action
On-line - If the Printer is On-line and not in the Menu system, pressing this key causes
a transition to Off-line. All pages currently in the paper path are printed and
then printing pauses until the printer is placed On-line. Status information via
SNMP or AppleTalk protocols is provided while in the Off-line state. Page for-
matting stops. On Parallel port, Off-line sends an XOFF if XON/XOFF hand-
shaking mode is selected. The DTR line is set to false.
- If the printer is On-line and in the Menu system, pressing this key exits the
menu system. The printer remains On-line.
- If the printer is Off-line and not in the Menu system, pressing this key causes
the printer to change to the On-line state, provided no operator intervention
condition exists. This key is ignored if an operator intervention condition exists.
- If the printer is Off-line and in the Menu system, pressing this key exits the
Menu system. The printer state changes to On-line, provided no operator
intervention condition exists.
- If in the Password menu, and the display indicates "Enter Password," press-
ing this key causes a password digit "0" to be entered.
- If in Power Saver Mode, not in the Menu System and the printer is Off-line
pressing this key to cause the printer to exit Power Saver Mode.
Menu Up - If in the menu system, pressing this key causes the Control Panel to scroll
through the menus in order bottom to top unless a higher priority message is
displayed, preempting menu navigation. Menu scrolling is available without
going to the Off-line state. Scrolling wraps, such that if the displayed menu is
the top menu, pressing this key scrolls to the bottom menu. If an item, value or
action is displayed, pressing this key returns to the top of the current menu
and removes the display of the item, value or action.
- If not in the menu system, pressing this key enters the menu system and dis-
plays the first menu.
- If in the Password menu, and the display indicates "Enter Password," press-
ing this key causes a password digit "1" to be entered.

Key Action
Menu Down - If in the menu system, pressing this key causes the Control Panel to scroll
through the menus in order top to bottom unless a higher priority message is
displayed. This will preempt menu navigation. Menu scrolling is available with-
out going to the Off-line state. Scrolling wraps, such that if the displayed menu
is the bottom menu, pressing this key scrolls to the top menu. If an item, value
or action is displayed, pressing this key returns to the top of the current menu
and removes the display of the time, value or action.
- If not in the menu system, pressing this key enters the menu system and dis-
plays the first menu.
- If in the Password menu, and the display indicates "Enter Password," press-
ing this key causes a password digit "5" to be entered.
Item Up - If in the menu system, pressing this key causes the Control Panel to scroll
through the items in the current menu, in order bottom to top, unless a higher
priority message is displayed, preempting menu navigation. Scrolling wraps,
such that if the displayed item is the top item, pressing this key scrolls to the
bottom item. If a value is displayed, pressing this key returns to the current
item in the current menu and removes the value from the display.
- If not in the menu system, this key is ignored.
- If in the Password menu, and the display indicates "Enter Password," press-
ing this key causes a password digit "2" to be entered.
Item Down - If in the menu system, pressing this key causes the Control Panel to scroll
through the items in the current menu, in order top to bottom, unless a higher
priority message is displayed, preempting menu navigation. Scrolling wraps,
such that if the displayed item is the bottom item, pressing this key scrolls to
the top item. If a value is displayed, pressing this key returns to the current
item in the current menu and removes the value from the display.
- If not in the menu system, this key is ignored.
- If in the Password menu, and the display indicates "Enter Password," press-
ing this key causes a password digit of "6" to be entered.
Value Up - If in the menu system and an item is displayed, this key causes the Control
Panel to scroll through the values for the current item in order bottom to top,
unless a higher priority message is displayed, preempting menu navigation.
Scrolling wraps, such that if the displayed value is the top value, pressing this
key scrolls to the bottom value. If no value for the current item is displayed
(Item key was pressed but Value key not yet pressed for this item), pressing
this key displays the default value for the current item. When setting a numeric
value, pressing this key increases the value by the step amount. It is subject to
auto-repeat if held down by more than 1 second, after which the value scrolls
repeatedly until the key is released. The increment for each step may be
greater than that for a single key press.
- If not in the menu system, and a paper mismatch condition does not exist,
this key is ignored.
- If a Paper Mismatch condition exists, pressing this key scrolls through the
alternate paper that may be used instead of the requested paper.
- If in the Password menu, and the display indicates "Enter Password," press-
ing this key causes a password digit "3" to be entered.
