•
By comparing the characters printed in the right column with the hex codes, you can verify
exactly what codes are being sent to the printer. If the code sent is a printable character
(20h-7Eh), that character is printed in the right column. If the code sent is a non-printable
character, such as a control code, a dot is printed.
•
To exit from the hexadecimal dump mode, turn off the power switch or press the
ALT
then
RESET
keys.

The self-test prints a continuous pattern of characters, either in draft or LQ. The font is determined
by the setup setting.

To initiate the draft self test, depress the LF key while either turning on the power. Continue
pressing the LF key until the print test begins.
•
To initiate the LQ self test, depress both the
LF
and
