							Running the Self Test
The built-in self test function demonstrates that the printer is
working properly. You can run the test with either continuous
paper or single sheets; this section describes the easier way,
with single sheets.
Caution:You should use paper at least 210 mm (8.3 inches) wide torun the self test; otherwise, the print head prints directly
on the platen.
1.Make sure the printer is turned off and the paper-release
lever is pushed back to the single-sheet position. Raise the
paper guide upright.

printing. The printer cover helps the paper feed properly.
5.To stop printing temporarily, press the Pause button.
6.To end the self test, make sure the printer is not printing.
Press LF/FF to eject the sheet; then turn off the printer.
Here is part of a typical self-test printout:
?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_abcd
=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_abcde
>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_abcdef
?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_abcdefg
@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\l]^_abcdefgh
ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_abcdefghi
BCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_abcdefghij

							Connecting the Printer to Your Computer
Your printer includes both a Centronics®
-compatible parallel
interface and an EIA-232D serial interface. Before you begin,
place the printer upright, as shown below. (This makes it easier
to connect the cable.)
Connect your computer to the desired interface as described
below.
You can connect cables to both interfaces; the printer switches
automatically to the appropriate interface when it receives data.
Setting Up the Printer1-13 
						

							Connecting to the parallel interface
You need a shielded, twisted-pair cable (not longer than
2 meters-6 feet) to use the parallel interface.1.Turn off both the computer and the printer. Plug the parallel
cable connector securely into the printer’s parallel interface.
Squeeze the wire clips together until they lock in place on
either side of the connector.
2.Guide the interface cable through the slot on the side of the
printer as shown in the illustration on page 1-16 so that it
does not block the paper supply.
Note:
If there is ground wire at the  end of the cable, attach it to the
ground connector to the right of the interface as shown in the
illustration on page 1-15.
3.Plug the other end of the cable into the computer’s parallel
interface. (If there is a ground wire at the end of the cable,
attach it to the ground connector at the back of the
computer.)
