The control panel switches can be pressed singly to perform the oper-
ations indicated by their names. Other functions can be obtained by holding
these switches down when you turn the printer’s power on. Still further
functions can be executed by pressing the control panel switches in com-
bination. This chapter explains all the switch and indicator functions.
Power indicator The power indicator lights (yellow) when power is on.
When paper is not present, the power indicator flashes. A beep tone
also alerts you to the need to load paper.
On Line switch The On Line switch sets the printer on-line and off-line. The state changes
each time you press the switch.
In the on-line state the printer receives data from the computer and
prints the data. In the off-line state the printer stops printing and sends the
computer a signal indicating that it cannot accept data.
The printer powers up in the on-line state if paper is present. If paper
is not present, the printer powers up off-line with the Power indicator
flashing. When you load paper the Power indicator stops flashing, but the
printer remains off-line. To start printing you must press the On Line switch
go on-line.
The three main times when you will want to press the On Line switch
are:
l Before and after any other panel operation
The other panel switches operate only in the off-line state. First press
the On Line switch to go off-line, then perform the panel operation, then
press the On Line switch again to go back on-line.
l To pause during printing
If you press the On Line switch during printing, the printer stops printing
and goes off-line, allowing you to check the printout or change a control
panel setting. Printing resumes when you press the On Line switch again
to go back on-line.
l To cut fanfold forms at the end of printing
When using fanfold forms, if you hold the On Line switch down for 2
seconds, in addition to going off-line the printer feeds the paper about two
inches forward, allowing you to cut it off just below the last line printed.
