The Nihon Kohden CardiFax ECG-6951E is a classic thermal array electrocardiograph. Its print head is a key component for reliably recording waveforms and text. This thermal print head heats a tiny array of dots to form an image on thermal paper, eliminating the need for ink or ribbons. It produces clear prints and is relatively easy to maintain.
Common Printhead Failures:
1. Printing on Blank Paper: If no print appears, the printhead may be completely damaged, not heating, or have a related circuit failure.
2. Printing on Faint or Incomplete Text/Waveforms:
- Printhead Aging: The thermal element loses sensitivity over time.
- Printhead Dirty: Coating debris and dust from the thermal paper accumulate on the printhead surface, hindering heat transfer.
- Improper Print Pressure: Too little pressure can cause poor contact.
3. Vertical White Lines on Printed Paper: This indicates that a specific heating point in the printhead is damaged or clogged.
4. Dark or Black Horizontal Lines/Bands on Printed Paper: This usually means that a heating point in the printhead is constantly heating, possibly due to an internal short circuit or a driver circuit failure.
5. Burnt Marks or an Unpleasant Odor on Paper: The printhead may be severely overheated and the printer should be shut down immediately.
