Preparing the Joint Plate

The joint plate aligns the base of the RWG500 to the
base of a SATO printer. This alignment ensures a smooth
label path and prevents problems during long periods of
continuous operation.

The following procedure adjusts the joint plate to suit the
base of different SATO printers, as shown here:

Use a Phillips

1

screwdriver
to loosen the
two screws
that secure
the movable
portion of the
joint plate.

Installing the Joint Plate

To align the printer to the RWG500 using the joint plate:

Place the non-movable

1

holes of the joint plate
under the feet of the
rewinder as shown. The
holes of the movable
plate should be facing
away from the rewinder.

Connect the Frame

2

Ground wire of the joint
plate to the Earth termi­nal on the rewinder.
Use a Phillips screw­driver if necessary.

Earthing completed

15

Installing the Joint Plate (cont’d)

Now place the printer

3

so that its feet at the
label output side will fit
into the positioning
holes on the joint place.

Make sure both the

4

printer and the rewinder
are turned OFF.
Locate the EXT con­nector of the printer and
use the supplied EXT
cable to connect the
printer to the rewinder’s
EXT connector.

16

Caution

Make sure that the
printer and rewinder are
aligned properly using
the joint plate. Other­wise rewinding errors
may occur.

Label Setup

The RWG500 offers two rewind directions and two types
of rewind shafts, as follows:

Rewinding Direction: Face in (CW) / Face Out (CCW)
Rewinding Shaft: Direct rewind/3” paper core rewind

About Rewinding Direction

Counterclockwise

winding (CCW)

In a CCW winding
direction, the printed
surface of the label is
always visible as it
faces outwards.

Clockwise

winding (CW)

In a CW winding direction,
the printed surface of the
label faces inwards and is
hidden from view. Only
the backing sheet (label
liner) faces outwards. The
rewind is set by default to
CW rewinding.

17

Label Setup (cont’d)

To change the rewind direction, use the Direction switch
found on the side panel of the rewinder. The factory set-

ting is CW rewinding by default.

Setting Rewind Direction

1. Before changing the rewind direction, make sure
the rewinder is turned OFF, or make sure that the
Status LED is blinking in green (rewinder in Idling
state)

2. Locate the Direction switch at the side panel, and
set it to either CW (clockwise, face in) or CCW
(counterclockwise, face-out).

3. Check the control panel display to confirm that the
appropriate CW or CCW LED is lit.

Caution

Change the rewind direction only when the rewinder is in
an idling state, or when it is turned OFF.

18

Label Setup (cont’d)

Besides setting the rewind direction, you can set up the
rewinder for direct rewinding or rewinding using a 3”
paper core.

About Direct Rewinding

Use direct rewinding when a paper core is not to be
used, and the label being collected will not need
reprinting or reprocessing in future.

Set the rewinder for

1

CW or CCW rewind
direction and load
the label accord­ingly. Wind the label
at the rewinding
shaft, and insert the
provided label clip
to fasten the label
onto the shaft.

Now insert the label
guide. The label

2

output from the
printer is now set
for direct rewinding.

19

Label Setup (cont’d)

You can collect output labels onto a 3” paper core for
more consistent winding, and if the wound label needs to
be unwound later for reprocessing/reprinting.

Rewinding on a 3” paper core

If label width is

1

below 65 mm,
attach one of the
provided 3” core
adaptors to the
rewinding shaft.
Otherwise, use two
adaptors. The
adaptor(s) should
be inserted so that
the metal plate teeth faces in the same direc­tion* as the rewind direction. Screw the adap­tor(s) into the narrow groove of the shaft.

* For CW and CCW rewinding, the metal

teeth must face left or right respectively.

20

Space the adaptor(s)
along the shaft to fit

2

the label width, then
tighten each locking
screw. Make sure the
screw fits into the
metal nut sliding
along the groove.

Label Setup (cont’d)

After properly inserting the 3” core adaptor(s), follow the
steps below to install the label.

Insert the 3” paper

3

4

tube core into the
rewind shaft. Affix
the leading (front)
portion of the output
label to the paper
core with some
adhesive tape.

Finally, insert the
label guide.

Caution

Before installing any label, always make sure that
the rewinder is OFF, or in an idling state (Status
LED blinks green).

21

Basic Operation

After setting up the rewinder to work with your SATO
printer, rewinding can be performed.

Turn on the rewinder. Wait for the status LED on

1

2

the control panel to start blinking in green. The
rewinder is now in idling status–ready to collect
labels from the printer.

Press and hold down the
START/STOP button on the
rewinder control panel. The
rewind shaft starts rotating,
and the tension arm rises
and stops automatically.
This process takes up any
slack in the label path.

When the Status LED is lit
in green continuously,
release the Start/Stop but­ton. The rewinder is now in
operation.

22

If you release the Start/Stop
button before the Status
LED lights up continuously
in green, repeat Step 1.

3

4

Basic Operation (cont’d)

Start the automatic rewinding by printing labels on
the printer. Each time a label is printed, the
rewinder automatically winds it outwards and
takes up any slack in the winding process.

When the rewinding is completed, press the
START/STOP button on the rewinder’s control
panel. The tension arm comes to rest and stops
automatically. The Status LED blinks in green to
signal the rewinder’s idling
status.

5

Remove the label on the printer, and then remove
the wound label on the rewinder. The wound label
can be removed easily because the tension arm is
inactive.

23

Winding 6” labels

To wind labels wider than 131 mm, the optional 6” Expan­sion Kit is required. The kit consists of the following:

1 Second roller joint

24

2 Second roller shaft guide

3 Core joint

4 Core shaft guide

Installing the 6” Expansion Kit

Follow the steps below to install the Expansion Kit.

Remove the cap
