(Refer Chapter 2, Section 2 and 3, to load the ribbon and label roll.)
Meaning of Beep Sound
1. Beep 1 time: Power on and printer is ready
2. Beep 2 times: Check the label roll. Maybe the roll is not yet loaded or not in the correct
position, or there are no labels.
3. Beep 3 times: Check ribbon. May be the ribbon is not yet loaded or finished out, or the
setup is not correct.
4. Beep 4 times: Printer head assembly is unlocked.
2-5. Using the Stripper
Stripper (Peeler) helps you separate the printed label from the liner paper one at a time. Only
when the separated label has been taken away, will another label be printed automatically.
1. Open the front cover and back cover.
2. Press the printer locks (part 14) to loosen the printer head assembly, and turn over the
head assembly.
3. Check if the stripper arm is on “on” position. If not, press it down to “on” position.
4. Load the label roll with at least 4 inches of liner paper past the platen (see figure 2.5.1a).
5. Put back the printer head assembly and fasten it.
6. Insert the front edge of the 4-inch liner paper between the stripper bar (part 19) and the
stripper roller (part 20).
7. Power on the printer, and press the paper feed button a few times until the front edge of the
liner paper appears through the stripper roller (make sure again: the stripper arm is now
turned down -- strip on).
8. If the liner paper does not appear at the right angle under the stripper roller, you should
adjust the label roll to right position (Loosen the printer head assembly again and lift up the
stripper arm, then you can adjust the label). Make sure the edge of the first label is under
the gap sensor (see figure 2.5.1b).
9. Turn up the strip sensor (see figure 2.5.2a), and you are ready to start printing the labels
(see figure 2.5.3). (Figure 2.5.2b show you how to turn down the strip sensor.)

2-7. To Install Memory Card
There are three types of external memory card (Flash Card, SRAM Card and Font Card) for
EZ-4TT. All the external memory cards have the same setting method. There is no difference
between the left and right slots. You might insert any of the above external memory cards into
either slot. Please follow the steps.
1. Power off the printer.
2. Open the front cover.
3. Put the tip of a screwdriver into the little groove which protects the Lids that cover the slots.
Lift the Lid off carefully with the screwdriver.
4. Please refer to the following diagram to insert the external memory card(s) into the slot(s).
(see figure 2.7.1)
Regarding the 2 memory card slots in EZ-4TT, you only can use it under one of the following
situations.
1. One SRAM card only.
2. One Flash memory card only.
3. One SRAM card & one Flash memory card at the same time.
Fig.2.7.1
Warning:
Power off the printer before
installing the memory card.
It is prohibited to use either two
SRAM cards or two Flash memory
cards at the same time.
2-8. To Install the Cutter
We suggest that the minimum label height be more than 35 mm. If you need any help in
installation and maintenance, please consult your supplier or dealer.

3. Maintenance and Adjustments
3-1. Cleaning the Printer Head
1. Open the Front cover and back cover.
2. Press the printer lock (part 14) to loosen the printer head assembly.
3. Turn over the head assembly.
4. Use a soft cloth soaked with isopropyl alcohol to remove the stuck label and cleans the
surface.
5. Put back the printer head and fasten it.
3-2. Adjusting Gap Sensor Sensitive
Only trained personnel must make any adjustment of the gap sensor, and it is highly
recommended that adjustment be made in a well-lit room.
1. Power on then open the Front cover and back cover.
2. Press the print er lock (part 14) to loosen the printer head assembly.
3. Turn over the head assembly.
4. Overlook the gap sensor (part 27). (see figure 3.2.1)
5. The Variable Resister (VR) can be adjusted by ways either counter-clockwise for higher
transmit power (higher sensitivity) or clockwise for lower transmit power (less sensitivity).
Any small amount of adjustment of the Variable resister has to be verified by pressing the
feed button at least 7 times.

a. When using the label roll
6. Remove the label from the liner. Load the liner paper under the sensor.
7. Press the micro switch and gently adjust the Variable Resistor. Right after the adjustment,
press the paper feed button at least 7 times (do not loosen the micro switch), until the LED
light turns red.
8. Put the label roll (with labels on the liner) under the sensor and press the paper feed button.
If the LED light is green, your adjustment is done. If the LED light keeps red, power off and
on, then repeat step 7 and gently adjust in reverse direction on Variable Res istor until the
LED light turns green.
b. When using plain paper
6. Press the micro switch and load the plain paper under the sensor. Press feed button and
look at the paper feed LED, it may be red or green. If green, go straight to step 8; if red, go
to step 7.
7. Adjust the Variable Resistor gently by clockwise for lower transmit power (do not loosen the
micro switch). Right after the adjustment, press the paper feed button at least 7 times, until
the LED light turns green.
8. Remove the paper from the sensor (do not loosen the micro switch), and press the paper
feed button. When LED turns red, the adjustment is done. If it is still green,

counter-clockwise for higher transmit power and power off and on, then repeat step 6.
3-3. Adjusting the Start Print Position
No matter whether the plain paper or label is used, setting
the horizontal start print position is the same way. Please
follow the steps.
1. Choose the expected distance “x” (from the left edge to
the start print position). In this case, we suppose the
distance is 4 mm (see figure 3.3.1).
2. Loosen the printer head assembly.
3. Move the gap sensor and choose the distance of 4mm
(from the left margin line to the digit “0” at the ruler). (See
figure 3.3.2).
4. Insert the label roll and move the label guide to close to
the roll's edge.
5. Put back and fasten the printer head assembly; then you
can try printing a label to test the gap sensor position.

3-4. Adjusting the Printer Head Pressure Screws
increase pressure
decrease pressure
When opening the front cover, you will see two screws right on the top of the printer head
assembly. When different paper material or ribbon material is used, you may need to adjust
the printer head pressure, by turning these two screws to decrease the pressure or vice versa.
If the pressure between the right and left sides of printer is not balanced, please readjust these
two screws.
