(*1) The power cord may not be included in the package. If it is not, make sure to use a
power cord that complies with the safety standards.
If any item is damaged, please contact your dealer for assistance.
Selecting a Location
Place the printer on a surface that is as horizontal as possible. Make
sure that the printer does not tilt more than 15 degrees.
The printer should be installed so that it does not move or vibrate
during paper cutting or the drawer kick-out operation.
Fastening tape is available as an option.
Setting Up the Printer 1–1
Adjusting the Paper Roll Near-End Sensor
Notes:
Use paper rolls with an inner core diameter of 10.5 to 12.5 mm so
that the sensor detects the remaining paper correctly.
When the last portion of a paper roll bears red markings, the
marking is sometimes an adhesive that pulls the entire paper roll up.
In this case, the sensor may not detect the remaining paper correctly.
If a paper roll easily becomes loose because of the quality of the paper
or other factors, incorrect detection of the paper end may result.
1. Make sure that the power supply is disconnected from the printer.
2. Two spacers are included. See the illustration below and decide
whether or not you want to use them. Use them if you want the
near-end sensor to be triggered when distance A is 3 to 4 mm;
otherwise it will be triggered when distance A is approximately
6mm.
3. Secure the paper roll near-end sensor (and spacers) with two
screws. When you insert the spacers, be sure you set the
spacers in the direction shown in the illustration.

computer.
Connecting the Drawer
WARNING:
Use a drawer that matches the printer specification. Using an
improper drawer may damage the drawer as well as the
printer.
CAUTION:
Do not connect a telephone line to the drawer kick-out
connector; otherwise the printer and the telephone line may
be damaged.
Plug the drawer cable into the drawer kick-out connector on the
bottom of the printer next to the power supply connector.

CAUTION / VORSICHT:
When connecting or disconnecting the power supply from
the printer, make sure that the power supply is not plugged
into an electrical outlet; otherwise you may damage the
power supply or the printer.
If the power supply’s rated voltage and your outlet’s voltage
do not match, contact your dealer for assistance. Do not
plug in the power cord. Otherwise you may damage the
power supply or the printer.
1–6 Setting Up the Printer
Beim Anschließen der Stromversorgung an den Drucker und
beim Herausziehen der Stromversorgung aus dem Drucker
darf die Stromversorgung nicht in eine Steckdose eingesteckt
sein. Andernfalls kann die Stromversorgung oder der Drucker
beschädigt werden.
Wenn die Nennspannung der Stromversorgung und die
Spannung der Steckdose nicht übereinstimmen, den Händler
um Hilfe bitten. Das Netzkabel nicht einstecken. Andernfalls
kann die Stromversorgung oder der Drucker beschädigt
werden.
1. Make sure that the printer’s power switch is turned off, and the
power supply’s power cord is unplugged from the electrical
outlet.
2. Plug in the power supply’s cord as shown below. Notice that
the flat side of the connector faces down.
3. Plug the power supply’s power cord into an outlet.
Note:
If you ever need to remove the cable, unplug the power supply’s
power cord from the outlet and then grasp the connector firmly at
the arrow mark and pull it straight out.
Installing the Ribbon Cassette
Use the EPSON ERC-38 ribbon cassette for your printer.
Note the label inside the printer cover that can assist you in installing
the ribbon.
Setting Up the Printer 1–7
CAUTION / VORSICHT:
Never turn the ribbon cassette’s feed knob in the opposite
direction of the arrow marked on the cassette; otherwise the
ribbon cassette may be damaged.
Den Transportknopf an der Farbbandkassette nur in die durch

kann die Farbbandkassette beschädigt werden.
1. Be sure the printer is not receiving data when you replace a
ribbon cassette; otherwise data may be lost.
2. Open the printer cover.
3. Turn the ribbon cassette’s knob in the direction of the arrow, to
take up any slack in the ribbon.
4. Insert the ribbon in the position shown in the illustration below
and push the ribbon cassette until it clicks.
Note:
Make sure that the ribbon is installed between the print head
and the platen without wrinkles or creases.

Be sure to use a paper roll that meets the specifications.
Do not use paper rolls that have the paper glued to the core because
the printer cannot detect the paper end correctly. However, if you
will stop the printing using the paper roll near-end sensor, you can
use glued type paper rolls.
1. Using scissors, cut the leading edge of the paper roll as shown
below.
2. Turn on the printer and open the printer cover.
