2.1.1 Printer Operating Switches and Indicators
Ready Indicator and Switch
The Ready switch puts the printer on-line or off-line. When the Ready indicator
(RDY) lights up, the printer is on-line and ready to print. When the Ready
indicator is blinking, the printer is off-line and will not print.
If you press the Ready switch while the printer is printing (putting it off-line),
the LA75 Plus will complete the line it is printing, stop, then move the paper
until the last line is visible.
Serial Port Indicator
The Serial Port indicator lights up when the printer receives data from the
serial port. When the Serial Port Indicator is not lit up, the printer receives
data from the parallel port.
Fault Indicator
The Fault indicator is amber. It lights up when the paper supply is exhausted
or nearly exhausted, or if there is a mechanical problem, and flashes
continously when the printer finds an electronic problem. (See Section 6.2.3 in
Chapter 6 to find the probable cause of the problem, as well as suggestions for
correcting the problem.)
Quiet Indicator
The Quiet indicator is green. It lights up when the printer is turned to Quiet
mode.
