Operation
1. Attach the appropriate cable between the printer
and your indicator. The connector on the printer
side is “keyed” so that you cannot plug the cable
in the wrong way. This means that the pins should
be positioned so that a slight pressure will seat
the cable properly. Do not force the pins in. Doing
so could damage the cable.
2. Plug the power cord into the back of the printer.
Plug the transformer into an appropriate AC
outlet. The unit will power up automatically and
print
Ready. This means the printer is ready to
print.
The paper feed switch on the printer is a rocker type
switch. Push the left side of the rocker switch to
toggle the printer on and offline. Push the right side of
the switch to advance the paper.
Your printer is now ready for printing.
The printer stores characters for printing until one of
two things happens:
1. The line buffer is filled.
2. It receives a line feed (hexadecimal 0A) or a
carriage return (hexadecimal 0D) code.
When (1) or (2) occurs, the printer prints out the
contents of its line buffer. If the buffer is empty when
the carriage return is received, the printer simply
advances the paper one line, leaving a blank line in
the printout.
Maintenance
When printing becomes faint or difficult to see,
replace the ribbon in your printer with an Epson HX-
20 cartridge ribbon.
