Connecting the Cables
CAUTION:
For a serial interface, use a null modem cable.
For a USB interface, do not turn on the printer before installing the
printer driver. Do not connect to electrical outlets close to devices
that generate voltage uctuations or electrical noise. In particular,
stay clear of devices that use large electric motors.
Never attempt to stretch the cables to enable a connection. The power
cable must have adequate slack at all times during use.

Serial Interface Settings
Note:
The printer interface settings are set at the factory for communication with KEP Flow
Computers. This provides a "plug-and-play" scenario in which neither the printer nor
ow computer serial interface settings need to be set in order for them to communicate.
If you are connecting the printer to a different device, you may need to change some
or all serial interface settings for proper communication. Check the required settings of
your device and use the Serial Interface Settings procedure explained below to change
the settings.
Settings Procedure
Note:
The printer interface settings are achieved by powering up the printer while holding
the FEED button. The printer will print the current setup, it will print instructions for
a SELF-TEST (short FEED button depression) or Mode Selection (long FEED button
depression)
1. Turn printer on while holding FEED button. Printer prints:

Page 8
2. MODE SELECTION: Press and hold FEED button to enter Mode Selection
4. SERIAL INTERFACE SETTINGS: Do 4 quick depressions to enter Selection 4: SERIAL
INTERFACE SETTINGS
3. CUSTOMIZE VALUE SELECTION: Do three quick followed by a long depression to enter
CUSTOMIZE VALUE SELECTION
Note:
You can then work your way through the Baud Rate and other settings one by one each
time returning to the SERIAL INTERFACE SETTING selection where you can then
select the next item to be congured (next Parity, then Handshaking, then Data Bits,
then Data Receive Error)
5. BAUD RATE: Do 1 quick depression followed by long depression to enter Baud Rate. Do the
same number of quick depressions as the number assigned to the desired Baud Rate (i.e. 3 quick
for 4800)

Page 9
6. PARITY: Do 2 quick depressions followed by long depression to enter Parity. Do the same
number of quick depressions as the number assigned to the desired Parity (i.e. 3 quick for Even)
7. HANDSHAKING: Do 3 quick depressions followed by long depression to enter Handshaking. Do
the same number of quick depressions as the number assigned to the desired Parity (i.e. 2 quick
for XON/XOFF)
8. DATA BITS: Do 4 quick depressions followed by long depression to enter Data Bits. Do the
same number of quick depressions as the number assigned to the desired Data Bits (i.e. 1 quick
for 7 bits)
9. DATA RECEIVE ERROR: Do 5 quick depressions followed by long depression to enter Data
Receive Error. Do the same number of quick depressions as the number assigned to the desired
Data Receive Error (i.e. 2 quick for Ignored)
9. EXIT SERIAL INTERFACE SETUP: Do one long depression of FEED button to exit Serial
Interface Setup. Do this again 2 times to exit setup and reboot printer.

Installing the Printer
You can install the printer horizontally on a at surface (with the paper exit on
top) or vertically (with the paper exit at the front). Also, you can hang it on a wall
using the included accessories.
CAUTION:
Take measures to prevent the printer from moving by vibration during paper cut-
ting and when using a drawer. Afxing tape is provided as an option.
Installing the Printer Vertically
When installing the printer vertically, be sure to attach the included control panel
label for vertical installation on the roll paper cover, and attach 4 rubber feet in the
rectangular indents in the printer case, as shown in the illustration below.

Page 11
Note:
You can install the printer so that the roll paper cover is upright to the mounting surface
using the included wall hanging bracket.
1. Attach the control panel label for vertical installation on the roll paper cover.
2. Install the wall hanging bracket on the printer, and x it using 2 included screws.
3. Attach 2 rubber feet in the rectangular indents in the printer case, and attach 2 rubber feet within
the scribed line on the hanging bracket.
4. Place the printer with the wall-hanging-bracket-side down.

Page 12
Hanging the Printer on a Wall
To hang the printer on the wall, follow the steps below.
CAUTION:
To x the printer securely, install the wall hanging bracket on a wall made of
wood, concrete, or metal. The thickness of the wall should be 70 mm {0.4"} or
more.
Be sure to use metallic screws.
The screws on the wall side must have a pull-out strength of 750 N (75.3 kgt) or
more.
1.Install 2 screws (screw diameter: 4 mm {0.16"}, head diameter: 7 to 9 mm
{0.28 to 0.35"}) in the wall at an interval of 80 mm {3.15"}. Make sure the
length of the screw's body in the wall is 10 mm {0.39"} or more, and the length
outside the wall is 3 to 4 mm { 0.12 to 0.16"}.
2. Remove the installed 2 screws from the printer, as shown in the illustration
below.
3. Install the wall hanging bracket on the printer, and fix it using the screws
removed in Step 2.

Attaching Cover on the Power Switch
The enclosed power switch cover ensures that the power switch is not
pressed accidentally.
You can tum the power switch on and off by inserting a sharp-pointed object
in the holes in the power switch cover. To detach the cover, also use a
sharp-pointed object.
A waterproof cover for the power switch is also included.
To use these covers, install themas shown in the illustration below.
WARNING:
If an accident occurs with the power switch cover attached, unplug the power
cord immediately. Continued use may cause re or shock.
Troubleshooting
No lights on the control panel
Check whether the power supply cable is correctly connected to the printer
and the socket.
Error LED on with no printing
• Check whether the roll paper cover is closed. If it is open, close it.
• If the Paper LED is on, check whether the roll paper is correctly installed and
any roll paper remains.
Error LED ashing with no printing
• Check whether a paper jam has occurred. If paper is jammed, remove the
jammed paper referring to the description below and install the roll paper
correctly.
• Printing stops if the head overheats and resumes automatically when it
cools.
• For other cases, tum the printer off, and after 10 seconds, back on.

Page 17
When a paper jam occurs
When a paper jam occurs, never pull out the paper forcibly. Open the roll paper
cover and remove the jammed paper.
CAUTION:
Do not touch the thermal head, because it can be very hot after printing.
If the roll paper cover does not open, follow the steps below.
1. Tum off the printer.
2. Put the ngers in the indents in both sides of the cutter cover, and slide it
toward the arrow in the illustration below to remove it.
3. Tum the knob until you see a triangle in the opening. This returns the cutter
blade to the normal position. See the operating instructions on the back of the
cutter cover.
4. Install the cutter cover.
5. Open the roll paper cover and remove the jammed paper.

Cleaning
Cleaning the Printer Case
Be sure to tum off the printer, and wipe the dirt off the printer case with a dry cloth
or a damp cloth.
CAUTION:
Never clean the product with alcohol benzine, thinner, or other such solvents.
Doing so may damage or break the parts made of plastic and rubber.
Cleaning the Thermal Head
CAUTION:
After printing, the thermal head can be very hot. Be careful not to touch it and to
let it cool before you clean it.
Do not damage the thermal head by touching it with your ngers or any hard
object.
Tum off the printer, open the roll paper cover, and clean the thermal elements of
the thermal head with a cotton swab moistened with an alcohol solvent (ethanol
or IPA).
We recommends cleaning the thermal head periodically (generally every
3 months) to maintain receipt print quality.
