What This Guide Helps With
Troubleshooting dockable table movement, eDrive, table travel, or docking faults before escalating for MRI service repair.
Step-by-Step Troubleshooting
Ensure Patient Safety First
If the patient is on the MAGNETOM Sola table and table movement, docking, or eDrive control is unreliable, stop movement immediately.
Support the patient, communicate with MRI staff, and follow site policy for safe patient removal or repositioning.
Expected outcome: The patient is protected from unintended table motion, incomplete docking, or unsafe transfer.
If patient safety is affected, stop troubleshooting and remove the system from clinical use.
Confirm the Reported Table or Docking Symptom
Ask MRI staff what occurred and when it occurred.
Confirm whether the issue involves:
- Table will not dock
- Table will not undock
- eDrive does not respond
- Table movement is slow, jerky, or intermittent
- Docking indicator does not confirm locked position
- Table movement fault appears on the console
- Table position is not recognized by the MRI system
Expected outcome: The fault is narrowed to table motion, docking recognition, eDrive control, or position feedback.
Verify the Scanner Is Not in Active Patient Operation
Confirm the system is not scanning, not preparing to scan, and not actively positioned for patient imaging.
Do not test table movement during an active exam unless directed by MRI clinical leadership and it is safe to do so.
Expected outcome: Troubleshooting occurs only when table movement will not place a patient, staff member, or accessory at risk.
Check the Area Around the Dockable Table
Inspect around the patient table, floor track area, docking interface, and bore entrance for visible obstruction.
Look for:
- Coils hanging over the edge
- Patient positioning pads caught under the table
- Cables pulled tight
- Linen, blankets, straps, or cushions interfering with movement
- Foot pedals, carts, stools, or floor debris near the table path
Expected outcome: The table has a clear travel path.
If an obstruction is found and removed, retest table movement. If normal operation returns, document the obstruction and stop.
Check Table Docking Alignment
Inspect whether the dockable table is physically aligned with the scanner docking point.
Confirm the table is straight, centered, and fully seated in the expected docking position.
Expected outcome: The table can mechanically align with the docking interface.
If the table was misaligned and docking works after realignment, return the system to service after normal function is confirmed.
Inspect the Docking Interface Externally
Visually inspect the docking interface without removing covers or disassembling components.
Check for:
- Bent or damaged external docking hardware
- Loose visible connector areas
- Foreign material at the dock
- Damaged latch surfaces
- Signs of impact from a stretcher, table, or accessory cart
Expected outcome: No obvious external damage is preventing docking.
If visible damage is found, remove the system from service and escalate for MRI service evaluation.
Check eDrive Enable Conditions
Confirm the eDrive control is being used as intended and that staff are engaging the control properly.
Verify the system is in a state where table movement is allowed and no safety interlock, emergency stop, or system message is preventing motion.
Expected outcome: eDrive commands are accepted when the system permits table movement.
If operation was blocked by workflow state or improper control use, verify normal operation with MRI staff and stop.
Verify Emergency Stop and Safety Interlock Status
Check whether any emergency stop, table stop, or safety stop function has been activated.
Confirm the system is not displaying a safety-related stop condition.
Expected outcome: No emergency stop or safety stop is preventing table motion.
If a stop was activated, follow site policy and MRI staff workflow before resetting. Retest only after the area is safe.
Check for Console or System Messages
Review the MRI console or operator display for table, eDrive, docking, or position-related fault messages.
Record the exact wording, fault code, and when it appears.
Expected outcome: Any active fault information is captured for service documentation.
If the system identifies a table/docking fault that cannot be cleared through normal user-level workflow, remove the scanner from service and escalate.
Test Basic Table Movement Without a Patient
With MRI staff approval and no patient present, test basic table movement using normal controls.
Observe whether the table:
- Moves smoothly
- Starts and stops normally
- Responds consistently to controls
- Reaches expected positions
- Produces unusual noise, binding, or vibration
Expected outcome: Table motion is smooth, controlled, and repeatable.
If movement is abnormal, stop testing and remove the system from service.
Check Table Position Recognition
Confirm whether the scanner recognizes the table position after docking or movement.
Watch for mismatch between actual table position and what the system reports.
Expected outcome: The table position is recognized correctly by the system.
If position recognition is incorrect or intermittent, suspect a sensor, encoder, interface, or internal table communication issue and escalate.
Inspect Table Accessories and Load Conditions
Remove unnecessary accessories, pads, coils, and nonessential items from the table.
Confirm there is no excessive load or uneven weight distribution during testing.
Expected outcome: The table moves normally under safe, unloaded conditions.
If the issue only occurs with a specific coil, accessory, pad, or setup, inspect that item and remove it from use if damaged.
Power Cycle Only if Appropriate
If MRI staff confirm it is appropriate, perform a normal system-level restart or table-related reset using approved site workflow.
Do not perform service-level resets, software procedures, or internal adjustments unless trained and authorized.
Expected outcome: A temporary control or communication issue may clear after a normal restart.
If the fault returns, document it as recurring and escalate.
Determine Whether the Fault Is External or Internal
If the area is clear, the table is aligned, accessories are removed, controls are used correctly, and the fault persists, the issue is likely internal to the table, docking hardware, sensor system, drive system, or scanner communication path.
Expected outcome: Troubleshooting stops before unnecessary disassembly or unsafe testing.
If the Problem Persists
If the MAGNETOM Sola dockable table or eDrive fault continues after external checks, common user-accessible causes have been ruled out.
The scanner or table should be:
- Removed from clinical use
- Labeled Out of Service
- Reported to MRI leadership
- Escalated to Siemens MRI service or qualified MRI service support for bench/system evaluation
Do not continue repeated table movement tests if motion is jerky, uncontrolled, noisy, misrecognized, or fails to dock securely. Knowing when to stop is proper troubleshooting.
Clinical Use Tip
Do not troubleshoot table movement with an active patient unless immediate patient safety requires controlled intervention. Move the patient to a safe alternative surface or device first whenever possible. MRI table motion faults can create patient transfer, positioning, and scan-delay risks.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"MRI staff reported that the Siemens MAGNETOM Sola dockable table would not complete docking and the eDrive movement control was intermittent."
Cause
What was observed during troubleshooting.
Example:
"External inspection found no obstruction, accessories were removed, docking alignment was verified, and the table still failed to confirm docked status."
Resolution
What action was taken.
Example:
"Removed the MRI system from service, labeled it Out of Service, documented the table/docking fault behavior, and escalated to Siemens MRI service for further evaluation."
Helpful Details to Include (If Known)
- Whether a patient was on the table when the issue occurred
- Exact table or eDrive fault message
- Docking or undocking behavior
- Whether table movement was slow, jerky, noisy, or completely inactive
- Whether the docking indicator confirmed locked status
- Whether the scanner recognized table position correctly
- Accessories, coils, pads, or straps present during the fault
- Floor or table path obstruction check
- Emergency stop or safety stop status
- Whether the fault was intermittent or repeatable
- Final device status
Final Thought
Dockable table and eDrive faults on an MRI system should be handled carefully because they affect patient movement, positioning, and safe scanner operation. Clinical Engineering should rule out visible obstructions, alignment problems, accessory interference, and workflow issues first. If the table still fails to move, dock, or report position correctly, escalation is appropriate and safer than continued testing.
That is successful troubleshooting.
