Step-by-step procedures to replace the thermal print head. 3. Essential Troubleshooting and Error Codes

Using certified weights to calibrate the full range of the scale. C. Printer Head Maintenance The thermal head is a consumable part.

The series scale (including the SM-3200, SM-3200B, and related models) is a staple in retail, deli, and grocery environments, known for its precision, reliable label printing, and robust construction. However, like all industrial weighing equipment, it requires regular maintenance and occasional servicing to maintain accuracy and compliance.

The manual provides "Exploded Views"—diagrams showing how the scale fits together. This is essential for safe disassembly without damaging the plastic casing or internal ribbons.

Locate the calibration switch (usually a micro-switch hidden under a sealed plate beneath the scale base or via a specific key combination during boot-up, such as holding the [RERE] or [TARE] key while switching on the power). digi sm320 service manual

High-reliability thermal head with a max width of 56mm and speed up to 105 mm/sec. 202 x 32 pixel FSTN LCD with backlight. Connectivity:

The Digi SM-320 integrates precise weight measurement with a robust thermal label printer. It operates on advanced digital signal processing to ensure legal-for-trade accuracy. Key Specifications:

The thermal printer is the most failure-prone component. The service manual details:

Gently wipe the heating element line along the edge of the printhead. Allow it to dry completely before reloading labels. Sensor Adjustments Step-by-step procedures to replace the thermal print head

The display will show SPAN or a zero-count code.

Note: The exact key sequence is crucial and is found in the "Calibration" section of the SM-320 manual. 2.2. Printer Mechanism Service A common issue is faint printing or jams.

| Symptom | Likely Cause | Fix | |---------|--------------|-----| | No power LED | Fuse F1 (internal, 3A slow-blow) blown | Replace fuse; check for short on VBAT input | | TX LED blinks but no link | Antenna mismatch or coax damage | Test with dummy load; measure SWR (<2:1) | | Intermittent serial data | Loose terminal block screws | Re-torque; check for cold solder joints on DB9 | | Overheating | Failed thermal pad between PA and chassis | Replace thermal pad (1.5mm, 3W/mK) | | Firmware corrupt | Power loss during update | Use XMODEM recovery via bootloader (hold ‘DEF’ button at power-up) |
