What This Guide Helps With
Printer not feeding paper, paper jams, or incomplete/failed ECG printouts caused by paper loading, obstruction, or feed mechanism issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- If actively performing an ECG, stop and move the patient to another functioning unit before troubleshooting.
- Expected: Patient care continues without interruption.
- Why it matters: Printing issues should not delay diagnostic results.
Verify the Reported Issue
- Attempt to print a stored ECG or test strip.
- Observe:
- No paper movement
- Partial feed or stopping mid-print
- Jam error messages
- Grinding or abnormal feed noise
- Expected: Issue is reproducible and clearly identified.
- Why it matters: Confirms whether this is a feed, jam, or print quality issue.
Check Paper Supply and Orientation
- Open the printer compartment and inspect the paper roll.
- Actions:
- Confirm paper is present and not empty
- Verify correct thermal paper type for CP 200
- Ensure paper is loaded in the correct orientation (thermal side facing print head)
- Expected: Paper is properly loaded and ready to feed.
- Why it matters: Incorrect loading is one of the most common causes of feed failure.
Inspect for Paper Jam or Obstruction
- Look inside the printer path for any blockage.
- Actions:
- Remove any jammed or torn paper
- Check for small scraps stuck in the feed path
- Ensure paper path is clear from roll to exit
- Expected: Paper path is completely clear.
- Why it matters: Even small debris can stop the feed mechanism.
Check Paper Roll Seating and Alignment
- Ensure the paper roll sits correctly in its holder.
- Actions:
- Reseat the paper roll
- Ensure it spins freely without resistance
- Confirm the roll is centered and not binding
- Expected: Paper roll rotates smoothly during feed.
- Why it matters: Misalignment can prevent proper feeding or cause skewing/jams.
Inspect Printer Door/Latch Closure
- Check that the printer cover is fully closed and latched.
- Actions:
- Close the door firmly until it clicks
- Inspect for broken or loose latch
- Expected: Printer recognizes the door as closed and ready.
- Why it matters: Many units will not feed paper if the door is not properly secured.
Perform a Power Cycle
- Restart the ECG machine.
- Actions:
- Power off the unit
- Wait 10–15 seconds
- Power back on and retry printing
- Expected: Printer initializes and attempts normal feed.
- Why it matters: Clears temporary software or control errors affecting the printer.
Test with Known Good Paper Roll
- Swap in a new, verified roll of thermal paper.
- Expected: Printer feeds normally with new paper.
- Why it matters: Old, curled, or incorrect paper can cause feed issues.
Listen for Feed Motor Operation
- Attempt to print and listen carefully.
- Observe:
- No sound → possible motor/control issue
- Motor running but no movement → possible roller/slip issue
- Expected: Smooth, consistent feed sound.
- Why it matters: Helps differentiate mechanical vs control-related issues.
If the Problem Persists
If paper is correctly loaded, the path is clear, and the unit still fails to feed or jams persist, the issue is likely internal (feed rollers, motor, or printer assembly).
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Knowing when to stop prevents further damage and supports safe, efficient troubleshooting.
Clinical Use Tip
Do not troubleshoot printer issues while a patient ECG is in progress. Always complete or repeat the study on a functioning device to avoid delays in diagnosis.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"ECG printer not feeding paper; unit displaying paper jam error."
Cause
What was observed during troubleshooting.
Example:
"Paper roll misaligned and small torn paper fragment obstructing feed path."
Resolution
What action was taken.
Example:
"Cleared obstruction, reloaded paper correctly, and verified proper printer operation with test print."
Helpful Details to Include (If Known)
- Paper type verified (correct thermal paper)
- Paper orientation checked
- Paper path cleared of debris
- Printer door/latch condition
- Feed motor sound observed
- Test print results
- Final device status (operational or sent for repair)
Final Thought
Printer issues on EKG machines are often simple and external—paper loading, alignment, or minor obstructions. A structured approach ensures quick resolution while avoiding unnecessary repairs. When the issue persists after these checks, escalation is the correct and safe decision. Proper documentation supports both reliability and accountability.
That is successful troubleshooting.
