Setting Up the Printer

1–2 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 is does not move or vibrate
during paper cutting or the drawer kick-out operation.
Fastening tape is available as an option.
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.

Setting Up the Printer 1–3
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
6 mm.
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 detecting lever moves freely.

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

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.

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.
