What This Guide Helps With
Troubleshoots loss of power, incomplete startup, or unavailable system operation caused by external power, connections, controls, or startup conditions.
Step-by-Step Troubleshooting
1. Protect the Patient and Maintain Continuity of Care
If the Ultimax-i is supporting an active procedure and becomes unreliable, stop using it for patient care when clinically safe. Move the patient or procedure to another verified imaging system according to departmental procedures.
Do not continue troubleshooting while a patient depends on unreliable imaging, positioning, monitoring, or procedural support.
Expected outcome: Patient care is safely transferred or delayed before technical troubleshooting begins. If continuity of care is secured, continue.
2. Confirm the Exact Startup Condition
Determine whether the system is completely dead, partially powered, stuck during startup, repeatedly restarting, or displaying a message. Note which consoles, monitors, indicators, or system components have power.
Ask whether the problem followed a facility outage, emergency-power transfer, shutdown, service activity, or abnormal restart.
Expected outcome: The failure is clearly categorized as no power, partial power, or incomplete startup. If normal startup completes during verification, troubleshooting can stop after functional testing.
3. Verify Facility Power
Confirm that the room has normal electrical service and that applicable facility disconnects or supplied power controls are in their normal operating state. Check for evidence that other equipment on the same electrical distribution is affected.
Do not reset facility breakers repeatedly or bypass electrical protection.
Expected outcome: Required facility power is available and no obvious room-level electrical problem is present. If restoring an approved external power condition corrects startup, verify operation and stop.
4. Inspect Accessible Power Connections
Inspect accessible power cords, plugs, connectors, and external power interfaces associated with the operator workstation and related system equipment. Look for looseness, damage, overheating, contamination, or evidence of accidental disconnection.
Do not open covers or access energized internal power assemblies.
Expected outcome: Accessible power connections are secure and undamaged. If reseating an approved external connection restores normal startup, proceed to final verification.
5. Check Emergency Stops and Safety Interlocks
Verify that accessible emergency-stop controls have not been activated and that obvious room or equipment safety interlocks are in their normal state. Reset an emergency stop only when the cause of activation is known and the area is safe.
Expected outcome: No active external safety control is intentionally preventing system operation. If correcting the condition restores startup, continue with functional verification.
6. Verify Startup Sequence and Connected Components
Confirm that normal operator-accessible system components are powered and started in the expected sequence. Check whether the acquisition workstation, displays, positioning system, and imaging components reach their normal ready states.
Avoid repeated power cycling. Use only normal shutdown and restart functions available to Clinical Engineering.
Expected outcome: All externally observable system components complete startup normally. If they do, the issue is resolved and troubleshooting can stop after verification.
7. Check for Environmental or Infrastructure Problems
Inspect the room for abnormal heat, water intrusion, construction activity, unusual odor, excessive dust, blocked external ventilation, or indications of a facility electrical or cooling problem.
If burning odor, smoke, liquid intrusion, arcing, or abnormal heat is present, disconnect from use and escalate immediately.
Expected outcome: The environment is suitable for equipment operation. Any identified facility issue is corrected before another startup attempt.
8. Perform Final Functional Verification
After correction, complete a normal startup and verify that the system reaches its normal ready state without repeated errors or unexpected resets. Verify basic operator interface, positioning availability, and imaging readiness without exposing a patient.
Expected outcome: The Ultimax-i starts consistently and all required subsystems become available. If successful, troubleshooting can stop.
If the Problem Persists
If the system still will not power on or complete startup, common external causes have been ruled out. The remaining problem may involve internal power distribution, startup control, subsystem communication, safety circuitry, configuration, or facility infrastructure requiring service-level diagnosis.
Remove the system from service, label it Out of Service, and send it for repair or bench/service evaluation as appropriate. Evaluation should use current Canon service documentation and approved test equipment. Internal repair, configuration changes, or component replacement should be performed only by qualified personnel.
After repair, complete applicable manufacturer functional checks, imaging verification, safety checks, and return-to-service documentation before clinical use.
Knowing when to stop external troubleshooting and escalate is proper troubleshooting.
Clinical Use Tip
Do not begin or continue an interventional procedure when system startup or readiness is intermittent; arrange verified alternate imaging capability first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the Canon Ultimax-i would not complete startup and remained unavailable for imaging."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found an accessible system power connection loose following room activity."
Resolution
What action was taken.
Example:
"Clinical Engineering secured the connection, restarted the system normally, and verified successful startup and basic imaging-system readiness."
Helpful Details to Include (If Known)
- Exact startup behavior or displayed message
- Components that did or did not power on
- Recent outage or room electrical event
- Emergency-stop status
- External connection condition
- Facility power status
- Unusual odor, heat, or sound
- Results before and after restart
- Final system status
Final Thought
Patient safety comes first. Verify simple external power, connection, safety-control, and environmental causes before assuming an internal failure, and escalate appropriately when normal startup cannot be reliably restored. Document the complaint, confirmed cause, corrective action, and return-to-service verification clearly.
That is successful troubleshooting.
