Testing the printer 47
Short test
The short test prints the version number of the software contained in the
printer’s ROM, followed by seven lines of text. If you are using a color ribbon,
each line is printed using a different color.
Long test
A long test continually prints the version number of the software contained in
the printer’s ROM, followed by the current User Setup Utility settings, and the
entire character set in each available font and pitch setting. This sequence is
repeated until you stop it by holding down the control panel’s Power button.
Since this test can generate many lines of text and graphics, it is a good idea to
perform this test only when using continuous fanfold paper rather than single
sheets.
Note:
Both the short test and the long test prints across the entire width of the
carriage. Make sure that the printer is loaded with the widest possible paper
available in order to avoid damage to the print head and platen.
Hexadecimal dump
This test prints in hexadecimal format all codes (character codes and control
codes) that are sent to the printer by the computer. The printer does not execute
any control codes (such as 0A - linefeed), it just prints them out. The
hexadecimal dump is useful when you are writing programs for printer control.
Use the following procedure to perform a hexadecimal dump.
❏ Set up the printer for a test print as described under “Testing the printer” on
page 46.
❏ Begin printing from your computer,
