I have purchased a replacement desktop scanner (Fujitsu iX-1600} to replace an old, similar scanner ( Scansnap S-1500 ).  

I had trouble installing it, until I closed Trend Micro (TM), now I can't scan without Trend Micr turned off.  The scanner service team advise me that this is a well known compatibility problem but had no advice on how to get round it.  I have added the scansnap functional folders to the exemption list on TM but the problem persists,  Is there a known fix?

Same here. Really annoying.  I use the scanner too often to be turning the Antivirus on and off all the time.

Hi @mbrothers and @jamesangst,

Thank you for bringing this to our attention. The issue with SnapScan has already been reported on our end. We will post an update as soon as we hear from our development team.

Thanks in advance for your understanding!

I imported all my old scansnap (S1500) records into Scansnap Home and now, even with Trend Micro running my new Scansnap iX-1600 suddenly seems to work.

Can't explain it, but I'll try it after restarting and with different settings and report back here if I come across problems.

tm_carlo, did you do something?

I also have this issue with my iX500 scanner.  I have found that when I start my computer with TrendMicro enabled, my Scan Snap scanner connections is not working.  If I then EXIT Trend Micro (deselecting Protection against viruses and spyware won't work - I have to exit Trend Micro), then I can start my Scan Snap normally.  Once it is running, I can then restart my Trend Micro and Scan Snap will continue to function.  if I restart my computer or log off, I have to exit Trend Micro again to get Scan Snap to communicate with my scanner.

Tried using my Scansnap with and without Trend Micro running and find the same thing as reported by nlafond.

Trend Micro must be turned off to enable the scanner, but once Scansnap Home is running it seems Trend micro can be turned on again without it disabling the scanner.

Hi @nlafond and @mbrothers ,

As of now, you can disable Trend Micro before using your SnapScan as a work around while the investigation of the issue is still ongoing on our end.

We will give you an update regarding this matter.

I have this exact same problem, Trend Micro is blocking the ix500 Scansnap driver from running. This problem started happening last week, after years of using this particular scanner with Trend Micro without any problem. Turning off Trend Micro works, but turning off the antivirus is not a solution. Please provide a better workaround. How do we add a USD driver to the exception list? 

Hi @davidmorin​,

Thank you for reporting this to us.

Regarding our exception list, we are only able to add the program that is installed on your device. You may check this link for instructions: How to add items in Trend Micro Exception List on Windows 

Regarding the concern, we are still investigating and will be providing an update about this matter.

I'm having exactly the same problems here.  TrendMicro is useless if it won't let us use standard equipment.  I have to exit Trend to get ScanSnap Home to run, then once it opens I can re-start Trend and am good for the day or until I need to restart or reboot.  TrendMicro ought to be able to figure out which .exe or driver they need to allow in order to let our iX1600's run at startup.  It allowed my iX500 to run for years with no problem. When it would no longer run I had to purchase an iX1600 and now have this problem, which leads me to suspect the reason the iX500 wouldn't work any longer was the same but why that would start after all the years of smooth functioning with TrendMicro is place is beyond me.  Please get the matter fixed promptly, and find some way of letting us all know when it's been done so we can stop having to exit Trend every time we want to scan something. 

Hi @jkazan​, 

We acknowledge the inconvenience this issue has caused you. Our developer's team is actively identifying the root cause and working on a solution promptly, given that numerous customers have been affected. We appreciate your patience and understanding during this process. Thank you.

 This actually occurs on other scanners as well.  I had an S1300 that was working fine and then I updated my trend.  It didn't work, so I thought it was my scanner since it is over 10 years old.  I upgraded to the ix1600 and it still didn't work.  Now I wonder if I didn't need a new scanner at all?  Check your updates Trend and find out what changed.

What I ended up doing was adding the program file to my exceptions list on Trend.  Now when I start my computer, I can use my scanner.  To do this, open up Trend Micro, click on Device, Click on Configure under Security Settings, Click on exceptions list, click +Add, find the PFU file under Program Files (x86) and then click open.  Click Apply in bottom right corner.  Then restart your computer.  It should allow you to open the ScanSnap Home program and allow you to scan.

For now, I'm bypassing this problem by scanning to the cloud and sometimes to my mobile.  Right into my Google Drive folder

2 days ago I did that as well, and it works fine now. However, Trend still needs to write a fix to allow the program to make it seamless for all.  I'm pretty sure I needlessly upgraded to the iX1600 when my earlier model Scansnap model stopped working without warning and without any way to discover this problem since it had worked just fine along with TrendMicro for years previously. 

@klaeder18​ 

What is the full name of the PFU file?

Hi @jkazan 
 
We already have a live case and managed to collect the necessary logs so Trend Micro Antivirus won't block SnapScan.
  
As of this moment, it has been submitted and is being analyzed by our developers.
  
Rest assured that we will provide you updates regarding this and will be integrated for future software updates.
  
For the meantime, adding the application to the exception list is the temporary workaround.

How do we get notified of the issue? I have 3 Scansnaps.
