Hi - Just installed a new Canon multifunction printer/scanner/copied (TS8250). Latest software installed. Using it on: iMac - Mojave MacBook Pro - Mojave On the iMac - I can print fine, but I can only Scan if KIS is not running. Both Canon's IJ Scan utility and Apple's Image Capture report they cannot communicate with the scanner if KIS is running. As soon as you quit KIS - Scanner works fine. Interestingly, if KIS is running, even if protection is fully disabled - the scanner does not work. KIS has to be fully quit for the Scanner to work. MacBook Pro - print and scan's fine (but does not run KIS at all). Any ideas what the problem could be here and how to fix? Many thanks in advance for any help!

Hello snaxo, As well as the advice from richbuff, please tell us: (1) KIS (free or licensed? - see below for this question), version? patch(x) x= letter (2) iMac, Mojave version? release? (3) How is Canon communicating/attached with/to iMac? (4) When the Canon Scan fails, is KIS application logging any events? Reports (guide is for KIS20, however, REPORTS feature is identical for KIS18, KIS19 & KIS20) (5a) If "yes", please export the report, save & upload, using the "upload" icon in your reply? --- (6) MacBook Pro - print and scan's fine (but does not run KIS at all), please explain this a little more please? Does this mean, KIS is installed and you're unable to activate or ?
  1. If KIS is installed and unable to be activated, please provide:
(6a) KIS (free or licensed? - see below for this question), version? patch(x) x= letter (6b) MacBookPro Mojave version? release? (6c) How is Canon communicating/attached with/to MacBookPro? (6d) KL Logs Gather tool for Mac OS (OS X) Please post back? Thanks so much. Kaspersky free has limitations, if we know the software in use we are able to provide more accurate analysis, information and solutions.

Hello snaxo, Thank you for replying & the information.
  1. May I know the Canon IJ Scan version please?
  2. If you connect TS8250 direct to Mac, via usb, does the scanner work?
  3. Can you check Canon IJ Scan (application) is in the trusted zone?
  4. When TS8250 was installed, was the Mac powered off/on at any stage during the printer install process?
Please let us know? Thank you

FLOOD
  1. 3.2.0
  2. I haven't tried to be honest, and trying is tricky at present (sorry)
  3. There was nothing in the trusted zone at all. I added the scanner ip address ( as http://192.168.1.146) - that didn't make a difference (but is that what I'm supposed to do exactly?)
  4. Nope
Thanks! :)

Hello snaxo, Thank you for the feedback:pray_tone3:. (1) Is IJ Scan Utility Ver.2.3.5 installed? Caution - For scanning, be sure to install this software (Canon IJ Scan Utility 2). (2) When you're able, try connecting TS8250 & Mac via usb - testing scanning using IJScan app? (3) Try adding an exclusion for Canon IJ Scan application - Edit the list of trusted files, folders (4) If Mac has not been powered off/on, since installing printer, please do so. (5) Now that TS8250 is installed, you could also try uninstalling KIS and reinstalling - reference documentation - Install and uninstall Kaspersky Internet Security Please let us know? Thanks

FLOOD Thanks again for your help. So to your points: 1) downloaded that - but that's worse - that won't even work when KIS is not running (!) 2) tried USB - did not make any difference 3) ok tried - no difference again 4) It has been, I've powererd it off / on several times now since with no luck 5) tried that. De-installed KIS 2019 and installed KIS 2020 at Tech Support's request. Still no change in behaviour unfortunately. Situation remains the same. Completely quit KIS - scanning works fine. As soon as KIS is running (even with protection disabled) - iMac has comms errors with the scanner.

Hello snaxo, Thank you for the update. Are the comms errors logged anywhere? Please retrieve that data and an image of the error/s? Please keep us updated with progress as Tech Support work thru this with you? Best regards.

Hello snaxo,
  1. Does TS8250 have a web interface?
IF "yes":
  1. Check 'Network' or 'Network protocol' tab, switch 'Enable IPv4 only' instead of 'Enable both IPv4 and IPv6.
  2. Power off TS8250 - leave it off.
  3. Power off / on Mac.
  4. Make sure KIS is active
  5. Power on TS8250
  6. Test scanning.
IF "no", check TS8250 - printer settings, follow 1 to 6 Let us know? Thanks Reference TS8250 Manual

I was able to disable IPv6 via the printer's web interface. Unfortunately, this has not made a difference.
Hello snaxo,
  1. Were steps:
  1. Power off TS8250 - leave it off.
  2. Power off / on Mac.
  3. Make sure KIS is active
  4. Power on TS8250
followed, after changing TS8250, IPv6?
  1. & have you checked TS8250, IPv6 setting, since powering printer on?
Please let me know? Thanks

Hello snaxo, Firstly, thank you for your absolute commitment to sticking with this and reporting back, I really appreciate your efforts:clap_tone3::pray_tone3:! I'm delighted the issue is fixed? Don't forget to tell the Lab it's fixed, IMPORTANTLY, they could document the fix so the Technical Specialists have the information available in their databases.
  1. If the issue returns, please let me know asap?!
Thank you, my very best regards and happy scanning! --- Re: "why does Canon/ TS8250/IPv6 being enabled cause the issue?" It's a known (Canon) issue, please seek information from Canon Technical Experts. -- Re: documenting as a Knowledge base / FAQ, I have no control of that "feature" of the Community Portal. That's a MODs domain exclusively. I once asked a MOD to upload an important FAQ and was roundly told off! Once bitten, twice shy. Maybe a MOD will read your post and upload the import fix information, or, you could ask a MOD, hopefully, not the same one I asked, otherwise you'll end up feeling:head_bandage:

snaxo, I'm truly delighted the issue is fixed, really, really happy:grinning::smile::laughing:. Please mark your post "answered" "Oh dear" is one way of putting it, not the words I used at the time:wink:. I mentioned it as a "caution", you may receive a completely different response or a MOD may proactively extract the relevant info and create a FAQ... My very happy regards:pray_tone3:
