4 Most Common O-Arm Problems Solved
Nothing is more frustrating that having to pause your imaging workflow to find a solution to an equipment issue. We've compiled the fixes for the four most common problems that you run into when working with Medtronic O-arms to help you get these systems back up and running in no time.
Each one of these sections are accompanied by step-by-step instructions with detailed pictures in case you're looking for more specific instructions.
#1 Your O-arm Won't Drive
When a stuck motion battery makes your 2,000lb O1 or O2 O-arm system stop driving, what's your next move? Whether it's old and aged out or low battery, both systems have a Drive Release Lever that can be activated. This takes the Power Drive System out of the loop and enables you to manually push the system around.
This lever can be near the base, behind the big wheel, or sticking out from this side or the other. You just kick it and it will pop out, engaging the drive release. Once that happens, the system can now be moved manually - you just might need a friend to help you push it.

#3 Your E-stop is Activated and You Can't Reset it
Ever struggled getting O-arm system's E-Stop to reset? We've been there. And the good news is that it's usually an easy fix. In 99% of cases, the problem is caused by the external pendant jumper.
By ensuring the jumper is securely plugged in and then hitting the reset button, you can quickly resolve the problem and carry on with your work.

#2 Your Hand switch has stopped working
A common issue with O1 and O2 O-arm systems is a hand switch failure during a case. You press the button to take an X-ray, but nothing happens. While the hand switch likely needs replacing (and Block Imaging can ship you a new one quickly), here’s a helpful method to get through the rest of the case without delay.
With the foot switch connected, you can perform all the necessary X-ray functions to complete the case even if the hand switch is not working. This workaround ensures minimal interruption while waiting for a replacement hand switch.

#1 The Door is Stuck in Closed Position
What do you do when your O-arm door is stuck in the closed position? While many people instinctively grab a socket wrench and start manually cranking, there’s a faster and safer alternative: the Emergency Door Override button. This button allows the system to open the door under its own power, reducing the risk of damage to the system’s components.
And if that doesn't work? We have instruction for how to correctly open the O-arm door using a rotor alignment tool and a socket wrench.
