1–2 Setting Up the Printer
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.

4. Check to be sure that the detecting lever moves freely.
Connecting the Cables and Grounding the Printer
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.

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.

1–8 Setting Up the Printer
CAUTION / VORSICHT:

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.

Setting Up the Printer 1–9

Notes:
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

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.
3. Insert the paper roll.
