(1) Black Mark Pitch (Dimension A)

Black mark pitch can be set to a dimension of A = 75 to 300 mm.

Note 1) Black mark pitches can be set to the above describe range, but it is recommended to use a

pitch that is at least 80 mm, in consideration of the variation in printing positions.

(2) Black Mark Dimensions

See the following drawings for the dimensions of black marks to be printed.

(3) PCS Value

The PCS value of black marks to be printed should be a minimum of 0.90.

Note 1) The PCS value of black marks can cause page skipping problems or improper page length

detection if they do not meet the aforementioned specifications.
For that reason, always ensure that the PCS value is met.

TUP900 Series Specifications Manual

Rev 0.01

(4) Top Margin (Dimension B)

Set the printing range, leaving plenty of top margin from the cutting position.
When not reversing paper feed, a top margin with a minimum total of 19 mm is recommended with the
distance of 15 mm from the thermal head heating elements to the cutting position and the empty paper
feed amount (1 line = 4 mm empty feed) considering the motor acceleration step.
If you want a smaller top margin setting, change the memory switch settings. However, in that case, it
is recommended to set the top margin of the empty paper feed amount (1 line = 4 mm empty feed)
considering the motor acceleration step.

Notes 1) If the top margin is not sufficiently taken, problems, such as the page being skipped, can occur.

So, you must set for plenty of top margin.

2) The setting of the printing range should not exceed the black mark pitch.

(5) Bottom Margin (Dimension C)

Set the printing range leaving plenty of bottom margin from the trailing edge of the printing range to the
black mark.
It is necessary to consider the printing precision of the black mark, the printing TOP accuracy (±2 mm of
the standard printing position), the setup ambient temperature of the printer, and part wear-out to set
the bottom margin. It is recommended that the following bottom margin be secured to set the printing
range.

Bottom Margin (Dimension C) ≥ 3 mm + (Dimension A × 3%)

Notes 1) If the bottom margin is not sufficiently taken, problems, such as the page being skipped, can

occur.
So, you must set for plenty of bottom margin.

2) The setting of the printing range should not exceed the black mark pitch.

(6) Example Setting of the Printing Region

The following shows a printing range setting example when not reverse feeding recording paper.

• When Black Mark Pitch (Dimension A) is 100 mm:

The top margin is set to 20 mm.
The bottom margin is set to 3 mm + (100 mm × 0.03) = 6 mm.
According to the above, it is necessary to set the printing range to less than 100 mm – 20 mm – 6
mm = 74 mm.

Note 1) If you have any questions regarding how to set the printing range for the black mark, consult

with STAR Micronics.

position of the near end sensor, adjust the roll diameter direction that determines the adjustment of the
paper width to correspond to the paper roll width and the amount to detect of that paper.
See the adjustment method for each below to use this at the correct position.

8-5-1 Adjusting to the Paper roll Width

Fig. 8.5.1 A and Fig. 8.5.1 B show the method for width direction adjustment for the near end sensor.
Loosen the screws fastening the near end sensor in the width direction with the paper roll you intend to use
mounted in the printer unit.
Move the near end sensor holder (plastic part) toward the paper roll edge (moving in the direction of the
arrow shown in Fig. 8.5.1 B) to make the paper roll edge and near end sensor holder edge close together.
In this state, move the near end sensor holder again in the opposite direction one or two clicks. At this time,
the distance between the paper roll edge and the near end sensor edge should be 1.5 mm to 2.0 mm.

Notes 1)To use the near end sensor under more optimum conditions, it is necessary to adjust the sensor

sensitivity. Refer to the sensor adjustment method described on the section 6-4 of the separate
TBD900 Specifications Manual to adjust the sensitivity.
Also, if the detection diameter of the roll sheet by the near end sensor is unstable, adjust the
sensitivity of the near end sensor.

2) The near end sensor is adjusted to the position corresponding to paper width of 111.5 ±0.5 mm
when the printer is shipped from the factory.

3) Use the memory switches to set the near end sensor on or off.

4) The adjustment for the near end sensor in the width direction on the optional high volume paper
roll supply (RHU-T900) is the same.

8-5-2 Adjusting to the Paper roll Diameter Direction

(1) Printer Unit

See Fig. 8.5.2 A to make adjustments on the near end sensor in the paper roll diameter direction.
To adjust the position of the near end sensor, the diameter direction fastening screws must be
loosened. After loosening the fastening screws, adjust the near end sensor to the appropriate position
for use. At that time, adjust the central position of the notch on the near end sensor with the references
shown in Fig. 8.5.2 A.
Also, it is possible to set to the user's preferred amount of paper roll to detect, so adjust to the most
optimum position while checking operations.
This printer unit handles paper roll of paper core inner diameter of φ25.4 (1 inch), inner diameter of
φ50.8 (2 inches) and φ76.2 (3 inches), but to use each paper roll holder, it is recommended to position
the near end sensor to the reference positions shown in the table below to use this apparatus.

(2) Optional High Volume Paper Roll Supply (RHU-T900)

The method to adjust the near end sensor when using the optional high volume paper roll supply, is
basically the same as that used for the printer unit.
However, be aware that the difference in the setting position of the paper roll (the position to mount the
paper roll bushing) makes the adjustment position different.
Fig. 8.5.2 B shows the reference inscribed on the optional high volume paper roll supply frame.
Also, the following explains two ways as representative examples to adjust the position.

9. HANDLING THE PRINTER UNIT

9-1 Precautions Regarding Designs

1. If the positional relationship of the printer unit and the paper roll holder mounting is poor, paper can
skew, the ends of the paper become creased or the paper jam. For that reason, be very careful in how
the paper roll is supplied. Also, if configuring the apparatus to use the optional high volume paper roll
supply, design particularly so that the center of the paper width on the printer unit and the center of the
paper on the high volume paper roll supply match.

2. Depending on the conditions of the paper roll that you intend to use, there are cases in which the paper
feed performance of the printer unit can be reduced. Design within the paper roll specifications.

3. Design the out cover so that paper transport is unobstructed at the paper discharge outlet.

4. Determine the layout of the cable from the printer unit so that no unnecessary load is applied to them.
Also, ensure that cable insulating covering is not damaged by the edges of the printer unit or the case.

5. Plated steel is used so rusting can occur on edges.

6. Design for gaps between the case and the printer unit or the high volume paper roll supply (optional) for
areas other than where attached.

9-2 Precautions for Handling

1. To prevent static electric damage to the thermal head's heating elements and the IC, handle the printer
only after preparing for anti-static and grounding yourself.

2. Handle the thermal head carefully because applying mechanical stress or shocks to it (including wear
out by micro-granules), it is possible to damage the heating elements.

3. We cannot guarantee the print quality or the life of the printer if you use any paper type other than that
we recommend. Therefore, always use the paper (thermal paper) recommended.

4. Be careful not to allow condensation to form. If condensation does form, absolutely do no turn ON the
power until it has evaporated.

5. Absolutely never directly touch the thermal head heating elements, the electronic components on the
control board, or the pins with your hands or a screwdriver.

6. Avoid leaving the printer without paper.

7. Be careful not to allow foreign objects to adhere to the recording paper and the platen.

8. Do not pull on the paper without opening the platen.

9. When closing the platen from an open state, check that it has been correctly locked by the locking
mechanism before operating the printer.

10. Do not apply excessive force to the cable connectors. Limit the number of times to attach and detach
the connectors to 10 times.

11. There are cases of discoloring of the recording paper, degradation of the coloring layer, the recording
paper and platen fusing together or paper curling in the paper feed path, if the printer is left unused for
extended periods. So, when using the printer after having been unused for extended periods, it is
recommended to install new recording paper because these phenomenon can cause improper printing
or poor paper feeds. Also, even if you do not replace the paper with a new roll, you should discharge
the part of the paper remaining for a long time in the paper feed path before using this printer.

12. The platen rubber may deform making printing thinner in some places, if the printer is left unused for
extended periods.

13. Initial print may be thin when using the printer in a cold environment because the thermal head is cold.

14. When using the printer in a high temperature environment, the print may run or characters may be
distorted.

15. Avoid sudden changes of the environment even if the ambient temperature and humidity are within
standard.

16. Do not store or use the printer in locations that are dusty, oily or exposed to metallic dust.

17. Because there is the possibility of mis-operation of the thermal head caused by noise, or damage to the
thermal head or IC caused by surged voltages, the power line should be stabilized.

TUP900 Series Specifications Manual

9-1

Rev 0.01

18. This unit is provided with an auto-cutter as standard equipment, but absolutely never approach the
auto-cutter blades while the cutter is operating because it is extremely dangerous. Also, if the cutter
stops, absolutely never touch the blades directly with your fingers.

19. Never unnecessarily disassemble the printer or its parts. When performing maintenance, always check
that the power has been turned OFF before starting your work.

20. The TUP900 series handles all paper widths within specifications. However, the width of paper on the
same mechanism (auto-cutter) is limited to one type.

21. LPS electrical power is used as the drive power for this unit.

9-3 Precautions Concerning Safety

To use this printer safely, you must carefully observe the contents described in the specifications
manual and the following precautions.
Also, we accept absolutely no responsibility for any fires or damages caused by any other type of
use of the apparatus.

1. During or after printing, the surface of the motor is extremely hot. Do not touch directly with your hands.

2. Do not touch the gears or rotating parts while the printer unit is operating.

3. Be very careful because there is the possibility of injury by handling the edges of the printer mechanism
(particularly the metal parts).

4. The yellow caution seal affixed to the front surface of the mechanism unit indicates that the thermal
head is very hot while printing or immediately thereafter, and that the paper tear bar (cutter) or the auto­cutter are extremely dangerous. Absolutely never touch them directly with your hands. The auto-cutter
particularly is also extremely dangerous when it is operating, so absolutely never put your fingers in or
near the auto-cutter blades or paper discharge outlet.

5. When performing maintenance on the printer mechanism, always unplug the power from its outlet
before starting your work.

6. Absolutely never apply a voltage that exceeds the maximum rating to the power connector.

7. The environment for use must be within the ranges specified in the environment specifications.

8. Do not drop foreign matter with electrical conductivity, such as paper clips, onto the PCB.

9. Do not disassemble or modify the units.

10. Absolutely never place the printer in an unstable location.

11. Never place the printer in a highly humid or dusty environment because there is the danger of printer
failure, fire or electrical shocks.

12. Never place objects or sit on the printer.

13. When not using the printer for an extended period of time, always unplug it for safety.

14. When the mechanism unit and presenter unit are rotating (when open), be careful not to allow your
fingers or hands to get caught in the rotating parts.

9-4 How to Set the Paper roll

Set the paper roll as shown in the following procedures.

 Procedure 1. Open the frame for fastening the mechanism (mechanism and presenter).

Hold the unit holder, as shown in Fig. 9.4 A, and open the frame for fastening the mechanism.
Then, lift the handle toward the direction of the solid line arrow (the top of the apparatus) to rotate it after
releasing the frame lock (the direction of the broken line arrow). Set as shown in Fig. 9.4 B.

 Procedure 2. Set the paper.

See Fig. 9.4 C to insert the paper roll holder unit into the paper roll core. Then, firmly fasten the left and
right hooks on the paper roll holder onto the paper core edges.
Also, be careful of he direction of the paper roll. The heat sensitive side (recording side) should face the
outside.
After setting the paper roll on the paper roll holder, fit the paper roll holder shaft into the printer unit
bushings to set the paper roll. (Fig. 9.4 D)

 Procedure 3. Load the paper into the mechanism.

After setting the paper roll into the printer unit, feed paper into the mechanism. Then, cut the leading
edge of the paper straight across, as shown in Fig. 9.4 E. If the leading edge of the paper is not cut
straight across, paper being loaded into the mechanism can become jammed.
Pass the leading edge of the sheet between the paper guide and damper rollers shown in Fig. 9.4 F and
insert it directly into the paper inlet on the mechanism. If the paper is not inserted straight, it can become
skewed.
Push the paper from the paper inlet on the mechanism further inside so that the paper sensor will detect
the leading edge of the paper. The paper will automatically be fed into the mechanism by the paper feed
motor. Then, the system will automatically cut the paper and perform a top of form operation to complete
the setting of the paper. Remove the excess paper at the discharge outlet.
Also, if you detect that the paper skewed when automatically set, reset or fix the paper.

 Procedure 4. Close the frame for fastening the mechanism (mechanism and presenter).

After completing the setting of the paper roll, rotate the frame for fastening the mechanism in the
direction opposite to procedure 1, to securely lock it. At this time, it is dangerous to use the apparatus
without it being completely locked, so be very careful.
Also, when the frame for fastening the mechanism is closed, be careful not to get your hands or fingers
caught.

9-5 Performing Maintenance

9-5-1 Cleaning the Thermal Head and Platen

To ensure long-term and stable printing, periodically clean the thermal head and the platen. It is
recommended that you clean every 500,000 lines.
The thermal head and platen can be cleaned by opening the platen unit with the release lever.

• To clean the thermal head heating elements, wipe with a cotton swab dampened with an alcohol based

cleaner (such as ethanol or methanol). Also, do not apply excessive force when doing so. Wipe the
heating elements gently. After cleaning, check that the alcohol has completely evaporated before closing
the platen unit.

• Use a soft, dry cotton swab to clean the platen. Wipe away the dirt while rotating the platen.

Also, complete wipe away all of the paper dust on the rubber platen. If the cleaning is incomplete, there
may be problems in paper feeds.

9-5-2 Handling Recording Paper Jams

If recording paper should become jammed, open the platen unit (including the presenter unit) and remove
the jammed paper.
Never pull on the jammed paper unnecessary while the printer unit is closed because this can damage the
drive system parts.
Fig. 9.5.2 shows the locations to operate (levers/knob) when paper becomes jammed. Remove jammed
paper according to the following procedures.

 Procedure 1. Remove the right and left lock levers.
 Procedure 2. Open the platen unit (including the presenter unit) using the release lever.
 Procedure 3. Rotate the knob to remove the jammed paper.
 Procedure 4. Close the platen unit (including the presenter unit) and lock the left and right lock levers.

Notes 1)When removing the jammed paper, never move you hands near the tear bar or the auto-cutter

because it is very dangerous. Also, when opening or closing the rotating portions, be careful
not to get your hands or fingers caught.

2) When locking the cutter blades, do not forcefully rotate the platen unit (or the presenter unit)
because this can be the cause of machine failure.
See the following pages for releasing the cutter lock and opening the platen unit.

9-5-3 How to Release the Cutter Lock

Use the following procedures to release the auto-cutter lock if trouble occurs, such as when paper becomes
chewed.

 Procedure 1. Turn the apparatus power off.
 Procedure 2. Rotate the emergency knobs in the direction of the arrows on the top of the auto-cutter

unit case to return the cutter blades to their home position.
The emergency knob should be rotated using a tweezers, screwdriver or ball-point pen to
prevent accidents.
