What This Guide Helps With
Identifies external causes of thermal printer failure, including paper jams, incorrect paper type, cable connections, and power issues.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
Confirm no patient is actively undergoing an EKG.
Expected outcome: Safe environment for troubleshooting without affecting patient care.
2. Check Printer Power
Verify the printer is powered on and indicator lights are normal.
Expected outcome: Printer powers on without error lights; ensures printer receives electricity.
3. Inspect Paper Supply
Ensure proper thermal paper is installed and seated correctly.
Check for jams or misaligned paper.
Expected outcome: Paper feeds smoothly; resolves most feed issues.
4. Verify Printer Cables and Connections
Inspect the printer’s data and power cables for secure connection and damage.
Re-seat connections if necessary.
Expected outcome: Printer communicates properly with EKG; eliminates connection faults.
5. Test Printer with a Self-Test or Demo Print
Use device menu to run a printer self-test (if available).
Expected outcome: Printer prints test page; confirms printer hardware functionality.
6. Check Device Settings
Verify printer selection and paper type in EKG settings.
Expected outcome: Correct configuration ensures print commands are sent properly.
7. Power Cycle the EKG and Printer
Turn both units off, wait 30 seconds, and power back on.
Expected outcome: Resolves temporary software or communication glitches.
If the Problem Persists
External causes are likely ruled out; the issue may be internal to the printer mechanism or control board.
Action:
- Remove device from service
- Label as Out of Service
- Send for repair or bench evaluation
Knowing when to stop prevents further damage and ensures patient safety.
Clinical Use Tip
Do not attempt to print on an active patient if printer issues are unresolved.
Use another EKG or printer for patient recordings until the issue is resolved.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Printer fails to print EKG strips."
Cause
What was observed during troubleshooting.
Example:
"Paper jam and misaligned feed roller identified during inspection."
Resolution
What action was taken.
Example:
"Cleared jam, reseated paper, verified successful self-test print."
Helpful Details to Include (If Known)
- Printer power light status
- Paper type and alignment
- Cable connections inspected
- Any error codes displayed
- Test print success/failure
- Final device status (ready for patient use or OOS)
Final Thought
Thermal printer troubleshooting requires a logical, stepwise approach, starting with the simplest external checks. Document each step clearly, escalate when internal issues are suspected, and prioritize patient safety. Proper CCR entries support accountability and future reference.
That is successful troubleshooting.
