6) Press the ON LINE button to put the printer on-line.
Now you have cancelled emphasized without affecting any other
modes.
Some users think that this procedure is too complicated and prefer
to cancel all the SelecType settings and then reset the ones they want.
Use whichever method you prefer. If you want to cancel modes
individually, remember to watch the ON LINE light. It blinks main-
ly on when a mode is set and mainly off when it is not.
Beeper Error Warnings
When the LX-80’s beeper sounds, it usually indicates that the
printer is out of paper. The beeper can also be sounded by any
program that sends the ASCII 7 code and by certain error conditions
in the printer itself.
If the printer beeps and stops printing when it is not out of paper,
turn the printer off and check to see if the paper is loaded correctly. If
the paper is loaded correctly, turn the printer back on and try to print
again. If the printer beeps and does not print again, take it to a
qualified service person.
Data Dump Mode
The LX-80 has a special feature that makes it easy for experienced
printer users to find the causes of problems. Called the data dump
mode, it gives a printout of exactly what codes reach the printer.
Turn on this mode by turning on the printer while holding down
the FF and LF buttons at the same time. The printer responds by
printing the words “Data Dump Mode.” Then, when you run a
program, either an applications program or one you have written in
any programming language, the LX-80 prints one or more lines. Each
line has three parts: the line number (four digits), the hexadecimal
codes (up to 16 numbers), and the guide section (16 characters at the
end of each line except the last).
The hexadecimal numbers are the codes received by the printer,
and the guide section helps you find a certain place in the list of codes.
Each character in the guide section corresponds to one of the codes. If
the code is for a printable character, that character is printed. If the
code is for a non-printable character, such as the ESCape code or the
code for a line feed or carriage return, a dot is printed.
