Button and LEDs
FEED BUTTON
Feeds roll paper or starts execution of a self-test or a macro.
POWER LED
On when the power is on. Flashes during an operation.
ERROR LED
Off when the printer is online, lights when the printer is
offline or feeding paper, and flashes when an error occurs.
PAPER OUT LED
On when the printer is out, or nearly out, of roll paper.
Flashes during standby for printing a self-test or running a
macro (when the macro execution command is used).
Loading Paper
Use only paper rolls and labels that meet specifications.
When using the printer horizontally, peel the backing sheet
off the paper exit guide and attach it as shown to prevent
paper cut by the autocutter from falling into the printer.
If you use roll paper smaller than the specifications, but with
an inside core diameter of at least 1" and an outside core
diameter of at least 1.25", do not attach the paper exit guide.
Otherwise, a paper jam may occur.
1. Open the paper roll cover using the cover open lever.
2. Insert a paper roll and pull out a small amount of paper,
aligning it with the guide, as shown below.
3. Close the cover and tear off the extra paper by pulling it
toward the front of the printer.

Installing the Paper Roll Spacer
To use paper rolls that are 38 or 70 mm {1.5 or 2.76"} wide,
install the paper roll spacer, as described below.

1. For rolls from 61 to 70 mm {2.4 to 2.76"}, break tabs off
the spacer. (For 38 to 61 mm paper, you can leave tabs on.)

2. Insert the paper roll spacer so that the front edge goes into
the notch and down to the shaft, as shown below.
3. Push the paper roll spacer until you feel it click onto the
shaft.

4. Slide the paper roll spacer to the appropriate width, as
shown above. You can use the measurement printed inside
the printer. Align the inside edge of the spacer with the
desired measurement.
5. Insert the screw included with the spacer into the hole
indicated above and tighten it. (Even if you can see two
holes, this is the only one to put the screw in.)
6. Follow the instructions in this guide to set the memory
switch for the desired paper width.
Testing the Printer
Follow these steps to run a self-test:
1. Load the paper roll and close the paper roll cover.
2. Hold down the ) ' button, and turn on the printer.
When printing starts, release the ) ' button. The printer
settings are printed.
3. The 3$3 5287 light starts to flash when the status has
been printed. Press the ) ' button to start the test.
4. After the printer prints the lines for the self-test, it prints
“*** completed ***.” The printer is ready to receive
data as soon as it completes the self-test.

1. Power off the unit, open the paper roll cover, and remove
the jammed paper.
2. If you cannot open the paper roll cover, paper is jammed in
the autocutter. Follow the steps under “Clearing the
Autocutter” below.
Clearing the Autocutter
1. Lift up and remove the cutter cover by inserting a flathead
screwdriver into the slots on each side of the main case and
spreading the case in the direction of the arrows.
2. Rotate the autocutter knob in the direction of the arrow to
return the cutter blade to the normal position. (A triangle
mark shows through the window in the autocutter frame.)
3. Open the paper roll cover, re-install the cutter cover, and
close the paper roll cover.

Memory Switches
Settings Made at the Printer
To set the memory switches, follow the steps below.
1. Be sure roll paper is installed. Open the paper roll cover and
turn on the power while pressing the ) ' button.
2. Press the ) ' button again twice.
3. Close the paper roll cover. The printer prints instructions
for items you can set on the printer manually.
4. Follow the instructions above to change the switch you
want to set.
5. After you have finished making settings, the printer saves
the settings, initializes, and becomes ready to print.
