What This Guide Helps With
Missing or incomplete cycle records caused by paper, loading, printer condition, connections, controls, or communication problems.
Step-by-Step Troubleshooting
1. Protect Documentation Requirements
Determine whether the facility requires a printed cycle record for load release or compliance.
If required documentation is unavailable, do not release loads solely because the sterilizer appears to have completed a cycle.
Expected outcome: Load documentation requirements remain protected while the printer problem is evaluated.
2. Confirm the Printer Symptom
Determine whether the printer:
- Does not power or respond
- Does not feed paper
- Prints blank paper
- Prints only part of the cycle
- Stops midway
- Produces unreadable records
- Misses selected cycle information
Expected outcome: The printer fault is clearly defined.
3. Verify Paper Supply
Inspect the printer for:
- Empty paper roll
- Incorrectly loaded paper
- Jammed paper
- Crushed or wet paper
- Paper path obstruction
Reload appropriate paper correctly.
Expected outcome: Paper feeds freely. If normal printing returns, troubleshooting can stop after verifying a complete cycle record.
4. Check Printer Cover and Mechanical Seating
Confirm the paper compartment, cover, roller, and accessible feed components are correctly seated.
Expected outcome: The paper path and feed mechanism are physically ready for operation.
5. Inspect Accessible Printer Connections
If the printer is externally connected or modular, verify accessible cables and connectors are secure and undamaged.
Do not open internal electronics beyond authorized service limits.
Expected outcome: All accessible communication and power connections are secure.
6. Verify Printer Enablement and User-Accessible Settings
Check only approved user-accessible settings to confirm printing has not been intentionally disabled.
Do not alter facility recordkeeping configuration without authorization.
Expected outcome: Printing is enabled as intended.
7. Perform a Controlled Print Test
Use an approved test function or run an appropriate test cycle to verify whether the printer produces a complete record.
Expected outcome: A full, readable record is produced. If so, troubleshooting can stop.
8. Compare Printed Record With Displayed Cycle Information
Confirm printed information corresponds with the completed cycle and is not truncated, garbled, or missing sections.
Expected outcome: The printer consistently captures the expected cycle record.
9. Check for Heat, Contamination, or Mechanical Damage
Inspect the accessible printer area for:
- Paper dust
- Debris
- Damaged rollers
- Loose parts
- Signs of overheating
Do not attempt internal printer repair beyond approved service procedures.
Expected outcome: No obvious external printer defect remains.
10. Escalate Persistent Printer or Record Failure
If paper, setup, settings, and connections are normal but records remain incomplete, remove the unit from clinical use if documentation is required for safe or compliant operation.
Expected outcome: The sterilizer is escalated appropriately rather than used without required cycle documentation.
If the Problem Persists
Common external causes such as paper loading, jams, settings, and accessible connections have been ruled out. Remaining causes may involve the printer assembly, printer interface, internal wiring, control electronics, memory, or software/configuration.
The sterilizer should be:
- Removed from service when required by facility policy
- Labeled Out of Service
- Sent for repair or bench evaluation
- Evaluated using appropriate Midmark documentation and approved test equipment
- Repaired or configured only by qualified personnel
Verify complete and accurate cycle record generation before return to service where printed documentation is required.
Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
A completed sterilization cycle and an acceptable documentation record are separate requirements when facility policy depends on printed cycle data.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Staff reported that the M11 printer stopped halfway through each cycle record."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the paper roll installed incorrectly and binding in the feed path."
Resolution
What action was taken.
Example:
"The paper was reloaded correctly, the feed path was verified, and a complete readable cycle record was produced during testing."
Helpful Details to Include (If Known)
- Printer response
- Paper type and condition
- Paper loading
- Jam location
- Print completeness
- Printer settings
- Cable condition
- Test print result
- Cycle record comparison
- Final device status
- Printer response
- Paper type and condition
- Paper loading
- Jam location
- Print completeness
- Printer settings
- Cable condition
- Test print result
- Cycle record comparison
- Final device status
Final Thought
Treat cycle documentation as part of the sterilization workflow, rule out paper and setup problems first, and escalate persistent printer or communication failures appropriately.
That is successful troubleshooting.
