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.

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.
