USB
The USB connector can be one of two types: a standard Type B connector, as in commonly
used in the PC industry, or a POS Powered USB connector. In the case of the powered USB
connector, there are a number of different versions. Make sure you are using a 24 volt DC
version, and the 24 volt supply meets the requirements of the iTherm
®
280 printer and any cash
drawer that is connected to the printer.
A powered USB interface is a special order option. There are several standards for the power
interface. Make sure that you inform TransAct is aware of what interface you require, and that
that interface connector is supported by the iTherm
®
280.
Verify the Firmware Configuration
An example receipt is Included in the box your printer shipped in that will show how the printer
was configured before it shipped from our Ithaca facility. Compare this information to your
system requirements. Pay attention to the emulation and the communications link. If they are
wrong, the printer may appear inoperative. If the configuration is not correct, refer to the section
on changing the iTherm
®
280 configuration. If there are a number of printers to be installed and
you want the identical configuration in each, you can use the universal configuration program to
record the configuration on one printer, and replicate it over a group. The configuration program
is available from Transact technical support.
Installing Paper
It is easy to install paper in the iTherm
®
280.
1. Open the paper cover by grasping the green cover release between your thumb and
forefinger, and squeeze the release. This will pop the cover up.
2. Open the cover and install a roll of paper with the paper coming off of the bottom of the
roll.
3. Lay the paper tail over the front of the printer and center it over the paper path.
4. Close the cover. When the cover is closed, the printer will feed several inches of paper
to make sure the paper is aligned in the printer. If equipped with a cutter, the printer will
automatically cut the paper tail and the printer is now ready to print. If the printer is not
equipped with a cutter, the operator should remove the paper tail.
