2-3. Handling Notes
(1) Install the printer near an easily accessible socket-outlet.
(2) Place the unit on a flat and stable surface for operation.
(3) Do not connect the AC Power Plug to the same outlet used for other noise
generating devices (large motors, etc.).
(4) Be careful not to drop paper clips, pins and other foreign objects into the
unit.
(5) Wipe off dirt with a soft cloth soaked in alcohol or benzine. Do not use
Lacquer thinner, Trichlorethelene or Ketone solvents because they may
damage plastic parts.
(6) Use a soft brush, etc. for cleaning the printer mechanism and PCB.
(7) Keep hands out of printer while power is on.
(8) Do not attempt to print when there is no ink ribbon or paper in the unit. The
print head life could be severly reduced.
(9) If the paper is fastened tightly to the roll, the paper may not detach from the
roll when the end is reached.
If this happens, the no paper detection function and paper feed will not
operate.
(10) Always keep the printer cover attached when printing to prevent paper
jams, noise, and other problems.
(11) Always turn the power off before opening the printer cover. (e.g. When
renewing a ink ribbon)

3-3. Part Functional Description
(1) AC Power Plug Connect to an outlet of the specified voltage.
(2) DC Power Outlet Supplies DC 12V power to the printer.
(3) Printer Cover Protects the printer against dust and reduces noise.
(4) POWER Lamp Lights up (green LED) when power is on.
(5) ON LINE Lamp Lights up (green LED) when the unit is in the online
mode.
(6) ALARM Lamp Lights up (red LED) when printer operation is not
normal, or the printer is out of paper. It is necessary
to install paper into the printer and press the ON
LINE Button to recover from paper empty status.
Turn off the printer power in order to recover from
abnormal operation.
(7) ON LINE Button Toggles between the on-line and off-line modes. The
printer will go on-line after turning power on.
(8) FEED Button Momentary operation of this button provides one
line feed. Pressing this button continuously will
cause continuous paper feed. If power is turned on
while pressing this button, self printing*1 will be
performed.
(9) Interface Connector Connects the printer to host computers. Check that
both computer and printer are off before connecting.
(10) DIP Switches Allows for setting of various functions according to
user requirements.
*1 Self Printing This printer has another convenient function, the
Automatic Test Printing. With the ink ribbon and
paper properly installed in the printer, turn the power
ON while holding down the Feed switch. Test printing will start and stop again automatically.

4. INSTALLATION OF INK RIBBON AND PAPER
4-1. Installation of Ink Ribbon
(1) Turn power off, lift the Printer Cover up and remove it.
Note: Be careful not to touch the print head immediately after printing,
because it can get very hot.
Figure 4-1. Printer Cover Removal
(2) Unwind ribbon so that the spools are separated as shown in Figure 4-3.
Hold the ribbon taut as shown with the drive pins facing down and slide the
ribbon between the print head and the platen. While keeping the ribbon taut,
wrap one side around the black ribbon guide on the end of the platen and
drop one spool on the spool shaft. As you move the spool downwards, move
the detecting lever aside to allow the spool to drop into place. Make sure the
spool drive pins engage with the spool drive holes. As the spool drops into
place there will be a click.
(3) While continuing to hold the ribbon taut, install the remaining ribbon spool
in a similar fashion.
(4) Turn the spool that rotates freely to take up the ribbon slack.

4-3. Paper Insertion
4-3-1. For Roll Paper
(1) Cut the Roll Paper end straight and square. Hold the roll so that the paper
comes from the bottom.
(2) Attach the Roll Paper to the Holders Paper by slipping one side of the roll
onto the Hub and pulling the other Hub out to allow the roll to slip in place.
(3) Insert the paper evenly into the Paper Insertion Slot.
(4) Turn the Power Switch “ON”, and press the FEED Button. The paper will
be fed into the unit.

4-3-2. Roll Paper Installation (When using the optional Printer Cover 8340R)
When installing roll paper with the optional “Ptinter Cover 8340R”, please use
the following procedure.
(1) Turn power off, lift the Printer Cover up and remove it.
Note: Be careful not to touch the print head immediately after printing
because it can get very hot.
(2) Insert paper into the printer, and feed the paper so it extends 3 inches or
more above the top surface of the printer.
(3) Insert the paper into the slot in the “Printer Cover 8340R”.
(4) Install the “Printer Cover 8340R” on the printer.
