1.1.1 Control Panel

The control panel is connected to the printer. It is fitted with four push buttons and
three LED's.

1.1.2 Push Buttons

On line / Off line
This push button switches the printer on and off line. When the printer is "ON LINE", it
is ready to accept data from the computer.
Likewise when it is switched "OFF LINE", the carriage automatically moves to the cen-
ter of the print span. When "ON LINE" the printer ignores the remaining push-buttons
(FF, LF, BF).
Form Feed
Paper advances by one sheet length (i.e. to the beginning of next page).
Line Feed
Paper advances by one line.
Back Feed
Paper retracts by one line.
When MP 2000 is "OFF LINE", the combined activation of the "ON LINE" and "FORM
FEED" push-buttons causes the printer to go "ON LINE". It assumes then the actual
paper position as "beginning of page". Three beeps are generated to acknowledge the
operation.

1.1.3 Signal Lights

Power
This indicator lights when the printer is correctly powered. When power voltage is un-
der 11.5 Vdc the "POWER" indicator flashes at 1 Hz rate. If the printer is battery ope-
rated, and the "POWER" indicator flashes at 1Hz rate, this means that the battery pack
is almost discharged, although the printer can still be operated for some time. Flashing
can be ignored or switched off (see 4.2.7).
