Setting Up the Printer

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.

Adjusting the Roll Paper Near-End Sensor

Notes:

Use rolls of paper 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 roll paper bears red markings, the marking
is sometimes an adhesive that pulls the entire roll paper up. In this
case, the sensor may not detect the remaining paper correctly.

If the roll paper 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.

1–1 Setting Up the Printer

2. Two spacers are included. See the illustration below and decide whether

Distance A

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 6 mm.

3. Secure the roll paper 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.

4. Check to be sure that the detecting lever moves freely.

Grounding screws

You can connect up to three cables and a grounding wire to the printer.
They all connect to the connector panel on the bottom of the printer,
which is shown below:

Notes:

There is a caution label beside the drawer kick-out connector.

Depending on the interface installed, the interface connector on your
printer may look different from the one illustrated.

Before connecting any of the cables, make sure that both the printer and
the computer are turned off.

Connecting the Computer

1. Plug the cable into the connector on the printer and tighten the screws
on both sides of the cable connector, as shown.

2. Connect the other end of the cable to the connector on your computer.

1–3 Setting Up the Printer

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.

Grounding the Printer

You need a ground wire to ground your printer. Make sure that the wire
meets the specifications below.

Thickness of wire: AWG 18 or equivalent
Diameter of terminal to be attached: 3.2

1. Make sure that the printer is turned off.

Setting Up the Printer 1–4

2. Connect the ground wire to the printer using the FG screw on the bottom
of the printer, as shown.

Connecting the Power Supply

WARNING:

Be sure to use the specified AC adapter. Connection to an improper power
source may cause fire.

CAUTION:

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 AC cable. Otherwise
you may damage the power supply or the printer.

1. Make sure that the printer’s power switch is turned off, and the power
supply’s AC cable is unplugged from the electrical outlet.

1–5 Setting Up the Printer

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 AC cable into an outlet.

Note:

If you ever need to remove the cable, unplug the power supply’s AC
cable 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.

CAUTION:

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.

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.

Setting Up the Printer 1–6

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.

1–7 Setting Up the Printer

5. Turn the ribbon cassette’s knob 5 or 6 times in the direction of the arrow
again, to take up any slack in the ribbon.

Installing Roll Paper

CAUTION:

Take care not to injure your fingers on the manual cutter

• When you remove printed paper

• When you perform other operations such as loading/replacing roll

paper

Notes:

Be sure to use roll paper that meets the specifications.

Do not use rolls of paper 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 roll paper near-end sensor, you can use
glued roll paper.

1. Using scissors, cut the leading edge of the roll paper as shown below.

Setting Up the Printer 1–8

2. Turn on the printer and open the printer cover.

3. Insert the roll paper.

Note:

Be sure to note the correct direction that the paper comes off the
roll as shown below.

printer feeds the paper automatically.
