Figure 2-9 Setup flowchart
2.1 Installing the Printer
You can install this printer only horizontally.
Install the printer in a flat, horizontal position.
End
Avoid locations susceptible to dust and other foreign matter.
Be sure to avoid bumping so that the printer is not exposed to strong impact during
operation.
Avoid placing the printer on top of the power supply or other cables or other objects.
Rev. A Setup 2-1
Fix the printer so that it does not move around when you open the printer cover and cut roll paper. A tape for fixing the printer is available as an option.
As shown in the illustration below, install the printer with a maximum tilt of 3°. Installing the printer with a tilt of more than 3° may cause the following problems.
Roll paper near end cannot be detected.
The printer cover will not close after installing roll paper.
Roll paper cannot be taken out.
Figure 2-10 Placed on a shelf
Note:
If the printer is located in a place with less space than in the diagram above, 1) it may not be possible to install roll paper and 2) the emergency cutter may not be able to cut the paper. Other problems may also arise.

2.2 Setting the DIP Switches
On this printer, you can make various settings with DIP switches.
Note:
Serial interface communication conditions must be set on serial interface model printers.
2.2.1 DIP Switch Positions and Steps for Changing DIP Switch Settings
Follow the steps below to change the DIP switch settings.
CAUTION:
Before you remove the DIP switch cover, turn the printer off. Otherwise, a short-circuit may cause the printer to malfunction.
1. Make sure the power supply for the printer is turned off.
