Symbol Description Alerts you to a medium or low risk hazard that could, if not avoided, result in moderate or minor injury. Alerts you to a potentially hazardous situation that could, if not avoided, result in equipment damage, data loss, performance deterioration, or unanticipated results. Provides additional information to emphasize or supplement important points in the main text. Version Version 1.0, published in January, 2023. 1 TX Exp Series RFID | Barcode Label Printer Users Manual Important Notes Important Notes Please read the following passages thoroughly before proceeding. Printhead The thermal printhead can be easily damaged due to its precision construction. A printhead damaged by misuse is not covered under the terms of the warranty. To ensure longevity of the printhead, please note the following:

DO NOT scrape or use tools that might damage the printhead surface.

To protect from corroding the printhead, DO NOT touch the printhead with bare hands.

DO NOT use thermal paper or thermal transfer ribbons which contain Na, K or Cl elements.

Keep the printhead from any form of liquid or dampness.

Only use a cotton swab dipped in anhydrous isopropyl alcohol to clean the printhead.

Always use high-quality consumables:

When the printhead module is closed, pressure is placed directly onto the printhead; dirt such as paper scraps, sand, dust and glue can scrape or damage the printhead.

The printhead is also easily damaged by static electricity, which may be generated by poor quality ribbons.

Always inspect consumables for high quality before purchasing. The printer functions under Direct Thermal or Thermal Transfer print modes. Thermal Transfer is set as the factory default (requires ribbon for printing). However, if you need to print on Direct Thermal materials (ribbon is not required), please contact your printer supplier or service provider to reduce the printhead pressure. This can protect your printhead from early performance deterioration due to direct contact with the thermal media. Any physical printhead damage caused by direct thermal printing is not covered under warranty. 2 TX Exp Series RFID | Barcode Label Printer Users Manual Important Notes Cutter (Optional) The printer equipped with a cutter can automatically cut the label after printing. However, automatic cutters pose a safety hazard since the blades are very sharp. To prevent injuries and cutter failures while using one of the many types of automatic cutters, please follow the safety and maintenance rules listed below:

Before using the cutter, be sure you have been trained by a qualified individual. A written

procedure covering the cutter's use is recommended. It is very important to choose the right cutter model for the application to ensure personal safety and prevent damage to the cutter caused by cutting wrong types of media.

Keep loose items such as long hair, clothing, jewelry, away from the cutter.

Don't put anything except print media inside the cutter.

Turn off power of printer if you notice abnormality with the cutting process and alert a qualified technician to resolve the issue.

Never cut a print media which exceeds the maximum operating conditions of the cutter.

Not every cutter model is designed to be able to cut through adhesive. Use only the dedicated cutters to cut through adhesive materials. Even so, regular cleaning is required to remove the adhesive built up on the blades over time to prevent cutter jam.

Routine inspection and maintenance are required to be performed by a qualified technician to keep the cutter in good working conditions. 3 TX Exp Series RFID | Barcode Label Printer Users Manual Chapter 1: Introduction Chapter 1: Introduction 1.1 Specifications Model Model with RFID Printing Mode TX2 Exp TX2r Exp TX3 Exp TX3r Exp TX6 Exp TX6r Exp Direct Thermal and Thermal Transfer Max Printing Speed 16 ips (406.4 mm/s) 12 ips (304.8 mm/s) 6 ips (152.4 mm/s) Max Printing Width 4.09 (104 mm) 4.16 (105.7 mm) 4.16 (105.6 mm) Max Printing Length 196 (500 mm) MPU GPU Memory HEATTM Level RFID Encoder Media Roll 64-bit, quad Arm Cortex-A53 core, maximum operating frequency 1.8 GHz GC NanoUltra 3D (1 shader) &GC320 2D OpenGL ES 2.0 2GB DDR4 RAM, 8GB managed NAND flash I Supports UHF EPC Gen 2, ISO 18000-6C protocols

Loosen the Thumbscrew. 2. Move the thumbscrew and adjust the Media Sensor Assembly to the appropriate position. Make sure that its position is directly over the gap, hole, notch or black mark. 3. Fix the Thumbscrew. Thumbscrew Media Sensor Pointer Mark Figure 3-50 Adjust the Media Sensor Position

The printer has three types of media sensors:

Transmissive sensor, detects gap, hole or notch between labels;

Lower reflective sensor, detects black mark on the backside of the media;

Upper reflective sensor, detects black mark on the front side of the media. The way to set the sensor type can be found in 3.2.1.3 Sensor Type.

When roll media is produced, the media end would be fixed on the media core with duct tape or scotch tape. If your printer cannot detect the Media Out signal well, please refer to Figure 3-51 to check the position of the tape. 77 TX Exp Series RFID | Barcode Label Printer Users Manual Chapter 3: Operations and Settings Hole Media gap Black Mark Black Mark Tape The tape shall avoid the hole area Tape The position of the tape should be made known to user to avoid positioning Media Sensors over the tape area.

Printhead damage or poor printout quality may occur if the procedure is not done correctly. The printhead pressure comes from two spring assemblies, the force generated by the two springs is transferred to the printhead via two Pressure Bars, as shown in Figure 3-52. Adjusting the position of a Pressure Bar changes the pressure across the printhead and platen roller, thus it has immediate impact on the evenness of printout. Adjusting Bolt Adjusting Knob Pressure Shaft Pressure Bar Figure 3-52 Printhead Pressure and Balance Adjustment Follow the steps below to adjust the printhead pressure:

1. Press down the Adjusting Knob, and twist the Adjusting Knob to align the numbered pressure level with the Adjusting Bolt to apply different level of pressure (The bigger the number, the more pressure the spring assembly brings to the printhead). 2. Repeat step 1 on another spring assembly to complete the adjustment of the printhead pressure. 79 TX Exp Series RFID | Barcode Label Printer Users Manual Chapter 3: Operations and Settings Follow the steps below to adjust the printhead balance:

1. To adjust the balance of the printhead, only one Pressure Bars position needs to be adjusted. Moving the Pressure Bar to the left increases the left side pressure of the printhead; moving the Pressure Bar to the right increases the right side pressure of the printhead. Always place one Pressure Bar at end position when making adjustments. Choose the left side or right side Pressure Bar to adjust, then slightly loosen the Pressure Bar by using the Allen wrench bundled with the printer. 2. Slide the Pressure Bar to an estimated position and fasten it with the Allen wrench. 3. Test print to check the evenness of the printout quality. 4. Repeat steps 2 and 3 until even printout is achieved. 3.3.3 Adjusting the Ribbon Tension Tension on both ribbon supply and ribbon take-up spindles can be adjusted, refer to Figure 3-53, by following the steps below. 1. Slightly loosen the Setscrew with the Allen wrench bundled with the printer. 2. To increase the tension, turn the Tension Adjustment Screw clockwise by the Allen wrench; to decrease the tension, turn it counterclockwise. The tension level can be read from the Tension Level Indicator. When tension is set at the desired level, fasten the Setscrew to complete the adjustment.
