Long test
❏Make sure that paper is loaded in the printer.
❏Turn the printer off.
❏While holding down the control panel’s LINE FEED button, turn the
printer on.
The long test prints seven lines of text and then continues to print the entire
character set for each font and pitch available.
❏To stop demo printing, turn the printer off.
Note:
●The long test prints across the entire width of the carriage. Make sure that
the printer is loaded with the widest paper available in order to avoid
damage to the print head and platen.
●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.
Hexadecimal dump
This procedure 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.
❏Make sure that paper is loaded in the printer.
❏Turn off the printer.
❏While holding down the control panel’s FORM FEED button, turn the
printer back on to enter the Hex Dump Mode.
❏The printer will now print out the hexadecimal values of any data that is
subsequently sent to it from your computer.
❏To exit the Hex Dump Mode, first press ON LINE to set the printer off-line,
and then turn the printer off.
