What This Guide Helps With

Troubleshoots recorder failures including no printing, paper feed problems, jams, poor print quality, incorrect loading, and external recorder-related causes.

Step-by-Step Troubleshooting

1. Protect Clinical Documentation and Monitoring Continuity

Confirm whether the recorder failure affects required clinical documentation or workflow.

If printed fetal monitoring records are required and the recorder is unavailable, clinical staff should use the facility's approved alternate documentation or monitoring process before troubleshooting.

The monitor's clinical display should not be assumed to replace required documentation unless facility policy allows it.

Expected outcome: Clinical monitoring and documentation continue through an approved alternate process.

2. Confirm the Exact Recorder Complaint

Determine whether:

Expected outcome: The specific recorder failure is clearly identified.

3. Verify the Correct Paper Supply

Confirm the installed paper is the appropriate type for the monitor and is loaded in the correct orientation according to the approved labeling or documentation available at the device.

Inspect the paper roll or stack for:

Expected outcome: Correct, undamaged recorder paper is installed properly.

If normal printing resumes after correcting paper loading, proceed to final verification.

4. Inspect the Accessible Paper Path

With the recorder stopped, inspect the user-accessible paper path for:

Remove only accessible obstructions that do not require disassembly.

Expected outcome: The paper path is clear and paper can move freely.

5. Verify Recorder Door or Cover Closure

Confirm the recorder cover or paper compartment is fully closed and mechanically seated.

Inspect the accessible latch area for damage.

Expected outcome: The paper compartment closes securely and the recorder is ready to operate.

6. Test Paper Feed Using Normal Controls

Use the normal paper-feed or recorder control to confirm that paper advances smoothly.

Listen for abnormal grinding, slipping, or repeated attempts to feed.

Expected outcome: Paper advances evenly without binding, slipping, or abnormal noise.

7. Replace the Paper With a Known-Good Supply

Install a known-good compatible paper supply.

This helps rule out aged, damaged, incorrectly stored, or incompatible consumables.

Expected outcome: Printing and paper movement are normal with the known-good paper.

If print quality or feeding is restored, troubleshooting can stop after final verification.

8. Evaluate Print Quality

Generate an appropriate test recording using normal monitor functions or a controlled simulated input.

Check for:

Do not adjust internal print mechanisms during external troubleshooting.

Expected outcome: The recorder produces a complete, readable tracing.

9. Check for Recorder-Specific Versus Monitor-Wide Failure

Verify that the monitor display and other primary functions remain operational.

If the monitor itself is restarting, freezing, or showing broader control problems, the complaint should not be treated as an isolated paper issue.

Expected outcome: The fault is correctly classified as recorder-only or part of a larger monitor problem.

10. Perform Final Functional Verification

With known-good paper installed, verify several normal feed and print operations using an appropriate controlled test.

Expected outcome: The recorder feeds paper consistently and produces a complete, readable record without jams or abnormal noise.

If successful, troubleshooting can stop and the monitor may be returned to service.

11. Escalate Persistent Recorder Failure

If the recorder cannot reliably feed or print with correct known-good paper and a clear paper path, stop troubleshooting.

Expected outcome: The monitor is removed from service when reliable recording is required and routed for bench evaluation.

If the Problem Persists

Paper type, orientation, paper condition, accessible paper-path obstruction, compartment closure, and normal feed operation have been checked.

Persistent failure may involve the recorder drive, print mechanism, sensing, control electronics, or another service-level condition. Do not disassemble the recorder mechanism or identify a particular internal part as failed without proper service evaluation.

The device should be:

Verify recorder performance and any applicable monitor functions before return to service.

Knowing when to stop external troubleshooting and escalate is proper troubleshooting.

Clinical Use Tip

Confirm how the unit records the fetal tracing within the facility workflow before returning a monitor with an unavailable recorder to clinical use.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Labor and delivery staff reported that the Avalon FM50 recorder would feed paper but produced an incomplete and faint tracing."

Cause

What was observed during troubleshooting.

Example:
"Clinical Engineering found the installed paper supply was damaged, while known-good compatible paper produced a complete readable tracing."

Resolution

What action was taken.

Example:
"Replaced the paper supply and verified smooth paper feed and consistent print quality during a controlled recording test."

Helpful Details to Include (If Known)

Final Thought

Recorder failures should be approached from consumables and the accessible paper path before internal mechanisms are suspected. Maintain required clinical documentation, verify normal feed and print quality with known-good paper, and escalate persistent mechanical or electronic failures appropriately.

That is successful troubleshooting.
