Common causes

  • 1Empty or snapped ribbon.
  • 2Print mode configuration conflicting with physical setup (e.g., trying to print with ribbon in Direct Thermal mode).
  • 3Misalignment of ribbon support shafts preventing sensor rotation detection.
  • 4Debris on the end-of-ribbon sensor.

Solutions

Quick Diagnosis

If the unit blocks with 7004 when printing in transfer mode, check if the ribbon take-up shaft is spinning and if the ribbon has consistent tension.

Step-by-Step Solution

  1. Visual check: Verify if the ribbon has snapped or run out.
  2. Correct loading: Ensure the coated side of the ribbon is correctly oriented toward the label.
  3. Print mode: Review printer configuration to ensure 'Print Method' is set to 'Thermal Transfer', not 'Direct Thermal'.
  4. Sensor cleaning: Clean the ribbon presence sensor (near the output shaft) with a dry cloth.

Maintenance and Prevention

Prevent loose ribbon by ensuring the take-up shaft is properly inserted and provides tension. Use appropriate ribbon widths to minimize slippage issues.

When to Call a Technician

If you test with a new ribbon and confirmed settings but the error remains, the ribbon motor's rotation sensor may be broken.

Frequently asked questions

It indicates the ribbon sensor detects no movement or presence of ribbon, locking printing in transfer mode.

Yes, if you configure the unit to 'Direct Thermal' and use thermal labels, but ribbon usage is disabled.

It usually fails due to wrinkled ribbon, incorrectly loaded ribbon, or an incorrect print mode configuration.

By correctly adjusting the shaft tension and printhead for the specific label roll width.
