printing operations and quality. It does not check the interface between the computer and
the printer.
The printing test prints all of the characters available in the ASCII character set.
To enter the Printing Test mode:
a) Make sure that the tractors are loaded with continuous feed paper and that the
paper select lever is set forward.
b) Turn the printer off.
c) Turn the printer back on while pressing the PRINT QUALITY key.
Do not press any keys alone or in combination, except for pressing the PRINT QUALITY key
alone when turning the printer on, to avoid initiating unexpected tests not permitted for the user.
