Can't scan on OJ8134e, using ScanSpeeder application

[Stevo51]

I have a full copy of ScanSpeeder (NitroLogic) useful because it can split scans into areas and save separately. It requires TWAIN. But cannot find the printer. 

I have located the HP Twain utility TwianUtilityUI.exe in the HPScan bin folder. However this also displays 'HP TWAIN The HP Imaging device was not found' then an error message Open Data Source failed.

Printer is on my network WiFi  only. 

Scanning using the HP Scan Application is working.

@Stevo51, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding HP OfficeJet Pro 8134e TWAIN Issues! 

We're thrilled to have the opportunity to assist you and provide a solution.  

It sounds like you're having trouble using TWAIN-based scanning with your HP OfficeJet Pro 8134e on a WiFi network. Here are some steps you can follow to resolve this issue:

Ensure Compatibility and Settings

Verify TWAIN Support: Confirm that the HP OfficeJet Pro 8134e supports TWAIN. Advanced TWAIN features and compatibility are typically supported by HP's scanning utility software.

Network Connection: Make sure the printer is properly connected to the network. Check that you can print from the computer using the same network connection.

Update Drivers:

• Ensure you have the latest HP drivers installed for the OfficeJet Pro 8134e. You can download and install the latest drivers from HP's official website.

Steps to Resolve TWAIN Scanner Detection Issues

Check TWAIN Settings:

• Open HP TWAIN Utility (TwainUtilityUI.exe) and try configuring scanning options.
• Verify that the scanner is listed and selected correctly in the software.

Scan Settings:

• Access your scanning software and confirm it is configured to use TWAIN. This is often found under settings or preferences.
• Ensure you have selected the correct source (HP OfficeJet Pro 8134e).

Firewall and Security Software:

• Make sure your firewall or antivirus software isn't blocking communication between your computer and the scanner.
• Add exceptions if needed to allow the HP scanning software and TWAIN utility through the firewall.

Troubleshoot Network Connectivity:

• Restart both the printer and the computer.
• Ensure that the printer and the computer are connected to the same network and can communicate.
• Check if the printer IP address is correctly set in the scanning software settings.  

Hope this helps! 

Take care, and have an amazing day!

Hello Zoey

Thanks for that I can tell you that as of this morning I was able to access the HP Expert Support Chat. This is ongoing my problem being escalated to advanced Printer /Scanner person who has yet to reply on the chat . 

However I will respond to your suggestions

1. OJ 8134e Does have TWAIN support

2. The printer is present on my Network via WiFi and Normal printing is working as is Flatbed Scanning with ScanSpeeder.  and All scan functions including The document feeder can be used with HP Scan Application.

3. HP Support assistant reports No Problems with any aspect of the Printer/Scanner setup

4. TwainUtilityUI.exe is present on my Computer in the Program Files (x86)/HP//HP Scan/bin folder (But not in the Printer Folder?). However when run it reports 'The HP imaging device was not found' and on clicking OK on the dialog an error. message pops up HP TWAIN 'Open Data Source Failed'.   

5. Scan settings in Scan Speeder, Document feeder settings do not include a viable driver option. It cannot see a (NET)  version. It can for the flatbed.

6. Firewall/VPN  I use Window firewall can't see that causing a Problem. I use Nord VPN tried turning it off made no difference.

7.No network problems

My own best guess would be that The drivers included with HP Scan work only for that app. and should be present in the Printer folder for that to work with a 3rd party Application. Other than that perhaps a conflict with HP Scan?  

Cheers

Steve

@Stevo51, welcome back! 😊

Thanks so much for the detailed follow-up — it really helps paint a clear picture.

You're absolutely right in thinking this may be a driver or interface-layer limitation. What you’re likely running into is that HP’s modern “Scan” app often uses WIA (Windows Image Acquisition) or proprietary APIs over the network, while TWAIN is pickier — it typically looks for a locally connected USB scanner or a TWAIN-compatible network scanner that exposes itself correctly to third-party software.

A few tactile next steps you can try:

Try USB Connection – Just for testing, connect the printer via USB to see if ScanSpeeder can now detect the TWAIN interface. If it works, that confirms the network-based TWAIN layer isn't being properly exposed to external apps.

Check for (Network) TWAIN Data Source – ScanSpeeder may be looking for a “HP OfficeJet Pro 8134e (NET)” source. If it doesn’t appear, that’s often a sign that the TWAIN driver isn’t correctly registering the network scanner.

Temporarily disable HP Scan-to-Computer – Sometimes HP’s own scan-to-PC feature hogs the TWAIN channel. Try disabling this from HP Utility or Printer Assistant and then relaunch ScanSpeeder.

Missing Registry Entry or DS File – TWAIN sources are referenced in the Windows registry and rely on specific .ds files in C:\Windows\twain_32\. If the driver installed doesn’t place one there (or for network mode), third-party apps like ScanSpeeder can’t “see” the device.

Hope this helps! 

Take care, and have an amazing day!

Hi Again

I received a reply today from Casper S on your team, he is of the opinion that the only way to approach this with any chance of a working solution is to use a direct USB connection.  

I had tried disabling scan to computer previously to no avail.

As I can live with using HP Scan if I want to use the Doc Feeder, I will leave it at that.

Thank you for a good technical description. I'm a retired Software/Electronics engineer, you can imaging how it feels to get a  'Turn it Off and On again'  type reply 😀. 

Cheers
