Introduction
Installing the Paper
The Model 122X impact printer series consists of
these models and electronic interfaces:
Model 1220 - RS-232
Model 1221 - Parallel
Model 1222 - TTL
Model 1223 - Current Loop
Model 1224 - RS-485
This manual is split into the following main sections:
• Introduction
• Installation
• Operation
• Maintenance
• Printer Test and Setup
• Communication
• Default Settings
Installation
Follow the precautions listed below when setting up
your printer. They are designed to help you keep your
printer working at its best.
- Plug your power supply into an appropriate
grounded outlet.
- Place your printer on a flat hard surface, like a
tabletop.
- Keep your printer out of direct sunlight.
1. Remove the printer cover by pressing on the
groove patterns to pop the front edge up. Lift off
the cover.
2. Press the rocker switch to the left. The light will
go off.
3. Unroll several inches of the paper.
Model 122X MiniPrinter User’s Manual 7
4. Cut a straight edge on the paper roll if it is
jagged. This will facilitate the entry of the paper
into the printer.
5. Slide the paper through the slot connecting the
paper compartment and the printer compartment.
You can slide it in about one-quarter inch before
it stops.
6. While holding the paper in place, press the
rocker switch to the Paper Feed position. The
printer will activate, and a rubber roller will pull
the paper into the printer compartment. Hold the
switch in the Paper Feed position until the paper
emerges from the top of the printer mechanism.
7. When an inch of paper has emerged from the top
of the printer, release the Paper Feed button.
8. Now pull the paper through the printer, until
several inches are exposed.
9. Slide the paper through the slot in the printer
cover.

10. Push the back of the printer cover down and into
place.
11. Press the front of the printer cover down to lock
in place.
12. Put the paper spindle into the paper roll as
shown below, and place the roll with the spindle
onto the snaps near the back of the printer. Turn
the paper roll to take up any slack in the paper
feeding to the printer. Make sure the roll of paper
turns freely. If it does not turn freely, the paper
will jam and will possibly damage the printer
mechanism.

To Remove the
Paper Roll
1. Advance the paper about one inch beyond the
paper cutter by using the Paper Feed switch.
2. Lift the paper roll away from the printer housing
and cut the paper feeding to the printer with
scissors. Try to make the cut as square as
possible to help the next time you reload the
paper.
3. Pull the remaining paper through the printer
mechanism. Be sure to pull the paper from the
top (paper cutter side).
Pulling the paper out
of the back of the
printer will damage
the print mechanism.

Operation
Connecting and
Powering Up
Your Printer
1. Attach the appropriate cable between the printer
and your host device. 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. Its 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
ERC-09 cartridge ribbon.
