Hey Guys, I'm having some issues with a sensor Gendex GXS-700 showing under devmgmt but the tool is not picking it up, I tried already updating Dexis I/O sensor drivers but sill, any suggestions?

image/png image.png

**Device Manager** is open on a Windows system showing a **Gendex GXS-700** dental intraoral X-ray sensor listed under "Dental Intraoral X-ray Sensor" with the label **"Gendex GXS-700 Size 1 before renumeration"**, indicating the device has not completed USB enumeration. The **GXS-700 / DEXIS Platinum** dialog box is open on the **Information** tab, with all fields (Sensor, Friendly Name, Sensor Type, USB Version, Sensor Driver Version, Sensor Firmware Version, CPLD Version, RPC Version) blank except **DxPicture Version: 4.2.1**. No error codes are explicitly displayed, but the empty sensor fields combined with the "before renumeration" device label indicate the sensor is not fully recognized.

Hmm is that gxpicture? If so see if you can reinstall it or update it as a test

Tech C 2025-01-10 19:28

I could be wrong, but I recall there is an issue with Dexis sensors, where the pc reads it, but the software doesn't, I think it has to do with that "before remuneration" in device manager @Sergey Starodub does it ring a bell to you?

Tech D 2025-01-10 19:33

it does. this means few things - drivers did not get installed properly, sensor is having issues, or I;ve seen this with the Platinum sensors when the DexisSensor Library was not installed or the wrong version was installed

Tech D 2025-01-10 19:33

what imaging software do they use?

Tech A 2025-01-10 19:33

prof.suni

Tech A 2025-01-10 19:33

I ran a repair to GXpicture on Dexis software manager, then they connected the sensor directly and it's being detected now on one of the rooms

Tech D 2025-01-10 19:34

holly fuck... profsuni is not just old, its an ancient software

Tech A 2025-01-10 19:35

Now the sensor is detected but when they try to take the image nothing happens 🫨

image/png image.png

**Prof.Suni dental imaging software** is open with patient "Pritchard, Terry" loaded. A **Sensor Capture** dialog is displayed showing the message **"Sensor Ready"** with the manufacturer identified as **"Gendex"**. A right-click context menu is partially visible in the lower right, showing options: **"Information…," "Image Settings,"** and **"Service."**

Tech D 2025-01-10 19:38

bring the xray head closer to the sensor

Tech D 2025-01-10 19:38

also, did u add the calibration files?

Tech A 2025-01-10 19:51

Yes the calibration files are all there

Tech A 2025-01-10 19:53

Now we have this message

image/png image.png

**Gendex Interface Error 2** dialog box is displayed on a Windows desktop. The message reads: *"The Gendex interface could not be created. Please be sure that there are enough system resources available."* A single **OK** button is present to dismiss the dialog; no additional error codes or numeric identifiers are visible beyond the title designation "Error 2."

Tech A 2025-01-10 19:53

And this one

image/png image.png

**DEXIS Software — Hardware Error Dialog** A Windows-style error dialog titled **"Hardware error"** displays the message: *"A hardware error has occurred. Please disconnect and reconnect the device. If the condition persists, please contact DEXIS Technical Support."* The dialog contains a red circle/X error icon and a single **OK** button; no error code or numeric identifier is visible.

Tech A 2025-01-10 19:54

But we were able to take one image

image/png image.png

The image shows a software window with the title bar labeled **"STB Tak..."** (truncated), with standard minimize, maximize, and close controls visible. The main content area of the window displays a **heavily corrupted or noise-filled screen** — the display consists of dense, horizontal scan-line artifacts or static, rendering any text or data within the window body **unreadable**. No error codes, numeric readouts, or diagnostic information can be discerned from the corrupted display area.

Tech D 2025-01-10 19:57

try outside of profsuni. you need to use the twain drivers

# Fix Gendex GXS-700 sensor not recognized by Prof.Suni imaging software

## Problem

A Gendex GXS-700 dental X-ray sensor appears in Device Manager but is not recognized by Prof.Suni imaging software. The device shows as "Gendex GXS-700 Size 1 before renumeration" in Device Manager, indicating incomplete USB enumeration. The DEXIS Platinum dialog shows blank sensor information fields except for DxPicture Version 4.2.1.

When the sensor is eventually detected, image capture fails with "Gendex Interface Error 2" stating insufficient system resources and hardware error dialogs from DEXIS software. Any captured images display as corrupted scan-line artifacts.

## Resolution

1. Run a repair on GXPicture through the DEXIS Software Manager
2. Connect the sensor directly to the computer (avoid USB hubs)
3. Verify the DexisSensor Library is installed and the correct version for the sensor
4. Ensure calibration files are properly installed for the GXS-700
5. Use TWAIN drivers instead of attempting direct integration with Prof.Suni
6. Position the X-ray head closer to the sensor during image capture

Note: Prof.Suni is legacy software with limited compatibility. The "before renumeration" status typically indicates driver installation issues, sensor hardware problems, or incorrect DexisSensor Library versions.
