Self test
Press and hold down the
feed button while turning the on /
off switch on. The printer will
then perform a self-test. A sample
slip of self-test result is printed as
in below sample. Please note that
both serial and parallel interfaces
are indicated. That means the
printer is working on an auto-
sensing and auto-select algorithm.
The header is printed in text
mode and the rest part of this slip
is printed in page mode. If FEED
button is pressed at this moment, a
font table will be printed in text
mode again. To exit the test printing, please turn the printer off
and on again.
