POWER INDICATOR – Glows green when the power is on.
PE INDICATOR – Stands for “Paper Empty”, and glows red
when the printer runs out of paper and when certain printer
malfunctions occur.
MODE INDICATORS – Either DRAFT or NLQ glows
green to indicate the mode (set by the Mode key or the DIP
switch).
MODE KEY – Changes the print mode every time it is press-
ed when the On Line indicator is off.
PITCH INDICATORS — Shows the character pitch current-
ly set: Proportional (PROP), Pica (136 characters/line), Elite
(163 characters/line), or Pica condensed (233 characters/line).
PRINT PITCH KEY – Selects one of the four available
character pitches when the On Line indicator is off.
TOF KEY – Ejects the current sheet, feeds a new sheet, and
moves the print head to the left margin when the On Line in-
dicator is off.
PAPER FEED KEY – .Advances the paper one line at a time
when the On Line indicator is off. If you hold the key down, you
get consecutive line feeds.
ON LINE KEY and INDICATOR – Glows green when the
printer is ready to receive data from your computer (on line).
When the printer is off line, it sends a signal to the computer in-
dicating that it cannot accept data. Pressing the On Line key
switches the printer between on line and off line. When you turn
the power switch on, the printer is placed on line automatically.
