This guide takes your Imagen sensor from the box to acquiring images directly in your practice imaging software. Two items, six steps, about 10 minutes — no IT experience required.
Only two USB devices this time. Each one connects at a specific step — this panel lights up as you complete them.
For a TWAIN installation you only need two items from your Imagen box, plus a Windows 10 or 11 computer with a free USB-A port and your practice imaging software already installed.
Imagen sensorWith its white protective cover — keep the cover on whenever the sensor is not in use.
Installer flash driveContains the TWAIN driver and your sensor's own calibration files, matched to its serial number.
Golden rule: the driver goes in before the sensor. Don't connect the sensor until Step 4 — plugging it in early is the #1 cause of installation problems. Already plugged it in? No harm done: unplug it and start from Step 1.
Tap each step when you finish it — the bar at the top tracks your progress.
Close all open programs, including your imaging software. If your antivirus is very aggressive, pause it during the installation (you can turn it back on right after).
Make sure you're logged into Windows as an administrator account.
Insert the installer flash drive into a USB port. Do not connect the sensor yet.
Open the drive in File Explorer and locate the TWAIN folder.
Inside the TWAIN folder, right-click the setup file and choose "Run as administrator".
Follow the wizard — accept and keep clicking through until it finishes. The driver and your sensor's calibration files are installed automatically.
Plug the Imagen sensor into a free USB-A port on the computer itself (avoid USB hubs). Always hold it by the connector — never pull or twist the cable.
Windows will recognize it in a few seconds.
Open your imaging software and go to its acquisition or device settings. Choose TWAIN as the image source, then pick the Imagen sensor from the device list.
Every program words this a little differently — it's usually called something like "Select TWAIN source" or "Acquire from TWAIN". If you can't find it, email us a screenshot of your software's settings and we'll point to the exact spot.
Slide a disposable hygiene sheath over the sensor (a new one for every patient).
Start an acquisition from your imaging software, position the sensor with the flat side facing the X-ray source, and press the exposure button on your X-ray unit. The recommended range is 60–70 kV — if you shoot with the XRD 70, its 70 kV output is a perfect match.
Your image appears in your software within seconds. That's it — you're fully installed.
Nine times out of ten it's one of these. Each fix takes under five minutes.
First, the obvious: check the sensor is firmly plugged in — and try another USB port on the computer itself (avoid USB hubs). Then confirm you selected TWAIN as the source and the Imagen sensor as the device (Step 5).
If it still doesn't appear: open Windows Device Manager and check whether the sensor is listed. If it isn't recognized, run all pending Windows Updates (including optional ones), temporarily disable antivirus and firewall, restart the PC, and run the TWAIN setup again from the installer flash drive. Then test again.
This is almost always Windows putting the USB controller to sleep. Open Device Manager → System devices → Intel(R) Management Engine Interface, right-click Properties → Power Management, and uncheck "Allow the computer to turn off this device to save power". Click OK and try again.
Run the TWAIN setup again from the installer flash drive and choose "Repair" when the option appears — it restores the driver and the calibration files in place. If the message persists after the repair, email us before trying anything else.
Each Imagen sensor has its own calibration files. If you use two or more sensors on one PC, run the installer once for each sensor's serial number — the calibration for each unit is installed automatically.
Email us with: your sensor's serial number (printed on the flat side of the USB connector), your Windows version, the name of your imaging software, what the error says, whether this is a first installation, and if possible a photo or screenshot. With that, we can usually solve it in one reply.
