Memory
backup function
This machine
is
capable
of
memory backup by cells. (Cells
are sold separately, though.) When the memory backup
func-
tion
is
effected, form position will
not
be affected by turning
on/off
of
power. Thus, handling
of
fan-fold paper can
be simplified. This function can be stopped
by
operating
pertinent function switch inside the machine.

• How
to
set form position
STEP
1.
Confirm that power source for the printer
is
turned
OFF
when the
ROM
unit
is
connected.
STEP 2. Insert 2 dry cells (SUM-3) into the cell case provid-
ed inside the main body.
For
details
of
the cells,
read the cautions given below.
STEP 3. Turn the function switch
(SWI-6)
ON, then supply
power to the printer.
STEP 4. Press the form feed switch. After form feed, pull
the manual feed knob to determine the form
position
of
paper. (See page 8)

•
When
PE
condition emerges, set the paper in accordance with the above-mentioned procedure again.
• When the memory backup function
is
to
be
utilized, do not turn the manual feed knob. Otherwise,
form position may be deviated.
• Wrong use
of
dry cells
will
cause leakage or breakdown.
Keep the following
in
mind when using them.
\.
Set the cells with their plus
(+)
and minus
(-)
sides correctly positioned
as
indicated on this
machine.
2.
Do
not
mix new and old dry cells for use.
3. Do
not
use
different kinds
of
dry cells. They may differ
in
voltage, even if their shapes are the
same.
4. Remove dry cells from this machine,
if
they are
not
to be used over a long period
of
time.
5.
There are charging-type and non-charging-type cells.
Read the cautions written
on
them, before using these cells.
• Do
not
turn
off
power when the following operation
is
carried out during memory backup.
Otherwise, form position may be deviated .
• Line feed
• Form feed operation
•
If
ROM
units are exchanged during memory backup, readjust form position
of
paper.
• Replace old cells with new ones every year, although the life
of
ce\1
differs depending
on
internal
discharge and frequency
of
use. (Trouble may occur to some cells,
due
to corrosion, etc.)
