Troubleshooting business and home label printers(M110,D30...)

I. Print Quality Issues

Q1: How to resolve blurry or unclear prints?

  1. Check battery level: Ensure >30% charge for lithium battery models; use alkaline batteries for models with self-installed batteries (carbon batteries have insufficient performance)
  2. Optimize content: Test with high-resolution images or bold text
  3. Clean print head: Use alcohol-dipped cotton swabs to clean the print head (operate when powered off). Tutorial video: https://www.youtube.com/watch?v=wtHZ9FAYcBQ
  4. Test materials: Compare results with other thermal papers

Q2: How to handle blank page printing?

  1. Correct installation: Ensure label side faces the white print head

  1. Self Print test:
  • For screen-equipped models: Select "Test Print" via power button
  • For non-screen models: Double-click power button
  1. Reset device: Use SIM eject tool to press reset hole (near charging port)

  1. Material check: Briefly expose label side to lighter flame - normal thermal paper should darken
  2. Device swap: Test with other phones/tablets


II. Paper Fedding Issues

Q3: How to adjust misaligned prints or skipped labels?

  1. Verify installation: Confirm correct paper positioning per manual. (For some printer with brackets, note that supplies need to be mounted to the right)

  2.Template settings:
      ① Ensure APP settings strictly match paper type (gap/continuous/black mark papers are incompatible)
      ② For D30, please scan the QR code on the box to get the template, or manually measure the label size before selecting.
   

  3. Calibrate sensor:
      NOTE: The paper roll must be removed when performing the following operations


Q4: Printer not detecting paper or red light?

  1. Installation tip: Ensure paper edge extends beyond print head for sensor detection

  1. If the printer still has a red light or displays Paper Not Detected, try resetting the sensor.

III. Other Issues

Q5: Frozen/unresponsive device?

  1. Hard reset procedure: Disconnect charging cable. While the device is powered on, use a pin to press the reset hole located near the charging port.


Q6: paper jam/abnormal noise?

  1. Density Adjustment: Reduce print density (in "Settings" or "Print Preview" page). High density settings may generate adhesive residue during heating, potentially causing paper feed issues.
  2. Check rollers: Remove debris from rubber rollers and gears


IV.Problems with PC software use (Labelife or drivers)]
