Self
Test
Printing
1. To
activate the
Self
Test,
load
paper
into the
printer
with the
printer
turned
off,
then hold down the LINE FEED switch
as
you
turn
the
printer
power
on.
The
printer
will
go
through
its normal
initialization
routines and
proceed to
print
the
test
pattern
in order of the ASCII
code numbers stored inside.
2. Push
the
STOP
switch
to
halt the self
test.
3.
Attempting to perform
a
self
test
with
no
paper
in the
printer
will result
in
move-
ment
of the
printhead,
but
no
printing performed.
4. If
self
test
does
not function,
check
Dip
Switch
2, assuring
that it is turned
on.
Automatic
Printing
Function
If
text
data is
input by
the
printer
that exceeds the
length
of
one
line,
the
text starts
printing
even
though
a
print
command
was
not
received. The
portion
of the
text
that
exceeds the line
length
is
printed
on
the
next
line.
If, however,
graphics
data
(including
repeated graphics printing)
is
input
that exceeds
the
line
length,
that
portion
of
the data
exceeding
the
line
is
ignored.
The mode
is
not
changed
in either
case.
Error Conditions
When
the
printer enters
an error
condition,
the
POWER
lamp
starts
blinking
and
an
ERROR
signal
is
output
to
the
computer.
An
error
condition is cleared
by
either
turning
power
off and
then back
on
again,
or
by
the
input
of
an
INITIAL
signal
from
the
computer.
Apple
or
Franklin
users
may
send
an
INITIAL
signal
from the
computer
with
a
CONTROL RESET.
Depressing
a
CTRL ALT DEL
on
the
IBM Personal
Computer
will clear the
error
condition. A
printer
error
condition
arises
only
when abnormal
sensor
timing
is
detected.
