PRECAUTIONS IN HANDLING THE PRINTER
WARNING
Please observe the following precautions for power source and power
cord:
Do not plug or unplug the power cord with a wet hand.
Use the printer only at the specified supply voltage and frequency.
Use only the specified AC adapter with the printer.
Check to make sure that the supply outlet from which the printer is
powered has a sufficient capacity.
Do not supply the printer from a power strip or current tap shared with
other appliances.
Do not plug the power cord into an electric outlet with dust or debris
left on the plug.
Do not use a deformed or damaged power cord.
Do not move the printer while its power is on.
• Neglecting to handle it properly may result in printer failure, emission
of smoke, fire, or electric shock.
• An overload may cause the power cord to overheat, catch fire, or the
circuit breaker to trip.
Do not allow anything to rest on the power cord. Do not place the
printer where the power cord may be stepped on.
Do not use or carry the printer with its power cord bent, twisted, or
pulled.
Do not attempt to modify the power cord unnecessarily.
Do not place the power cord near any heating device.
• Neglecting these cautions may cause wires or insulation to break,

If the power cord sustains damage, contact your Citizen Systems
dealer.
Do not leave things around the electric outlet.
Supply power to the printer from a convenient electric outlet, readily
accessible in an emergency.
• Pull the plug to immediately shut it down in an emergency.

the host system’s hardware.
Only use the printer with devices that have designated solenoid
specifications for the cash drawer interface connector.
• Neglecting this caution may result in malfunction or failure.
THIS LABEL INDICATES THE
RISK OF BURNS DUE TO THE
HIGH TEMPERATURE OF THE
PRINT HEAD AND A RISK OF
BEING CUT BY THE MANUAL
AND AUTO CUTTERS WHILE
THE PAPER COVER IS OPEN.

—7—
CAUTION
To prevent injury and printer failures from worsening, observe the following:
While the paper cover is open, be careful to not touch the manual
cutter that is in the paper eject slot.
Do not touch the printing surface of the thermal head.
Do not touch any of the moving parts (e.g., paper cutter, gears, active
electric parts) while the printer is working.
In case of trouble do not attempt to repair the printer. Ask Citizen
Systems service for repair.
Be careful that the covers do not pinch your hands or fingers.

For severe stains, use a soft cloth slightly dampened with water.
Never use organic cleaning solvent such as alcohol, paint thinner,
trichloroethylene, benzene, or ketone. Never use a chemically
processed cleaning cloth.
To remove paper dust, use a soft brush.
CAUTION
• The thermal head is at a dangerously high temperature immediately after printing.

Paper end sensor (PE sensor)
Detects when there is no paper. Printing stops when this sensor detects there
is no paper.
Buzzer
Buzzes when errors occur or when operations or command operations are
performed.
User memory
You can save user-defined logo and character data in this memory. Data
remains stored in this memory even if the printer is turned off. For
information on how to save data, refer to the Command Reference.
Memory switch
Setting of various kinds of functions can be stored in memory. Settings
remain stored in the memory even if the printer is turned off.
USB power supply OFF (When memory switch MSW6-3 is set to ON)
When the printer is connected to a PC by USB, turning off PC power or terminating
the USB connection causes printer USB power to turn off three seconds later.
This mode is canceled when the PC is turned back on or when a USB connection
is established.
Paper saving functions
Memory switches MSW8-3 through MSW8-5 can be used to configure the
settings below, which save paper.
•Top margin suppression
The printer back feeds the paper before printing which reduces the blank space
at the top edge of the paper.
The back feed amount can be specified.
•Line gap reduce
Automatically compresses the linefeed amount between lines. The compression
ratio can be specified.
•Text compression vertical/horizontal
Makes the print size smaller.
The compression amount is specified by a combination of vertical and horizontal
compression ratios.

CAUTION
The POWER LED is unlit when USB power supply is OFF, and the power OFF state cannot
be identified.
Pressing POWER while USB power is off does not turn on power immediately. After a
while, USB power supply OFF is canceled and pressing POWER turns on power normally.

Auto side shift (MSW8-6)
This function dissipates heat load during frequent heat generation by a vertical
ruled line or other specific head heating element.
If no data is received within 15 seconds after each cut or print, the print position is
automatically slid N* dots to the right. The original print position is returned to at
the next slide timing.
* N is the MSW8-6 setting value.
CAUTION
Before configuring the top margin suppression setting, first remove any partially cut paper
from the printer. Failure to do so can cause the cut paper to be torn off by the next print
operation, which can cause printer trouble.
Note the following precautions when using text compression.
• Compressed text is more difficult to read than the original text.
• Horizontally compressing text also makes the print range smaller, so the number of
print lines does not change. Pay close attention to the print range when using
narrow paper.
• Do not use compressed text when printing a bar code. Doing so may make the bar
code unreadable.
If the right margin is too narrow, this may result in some print characters being cut off. This
function is disabled under initial settings. To enable this function, use MSW8-6 to specify an
appropriate value for the maximum slide amount.
