MAXIFY GX7021 No TWAIN Dialog for Duplex ADF Scanning


Apparently the automated assistant doesn't know the product name.  I get caught in a loop being asked, giving it, prompted to select a product category, told where to find the product name, being asked for the product name....endlessly, until it says please find the name and call us back.  It's "MAXIFY GX7021"- says it right on the front of the machine, on my sales invoice, etc. etc.

YES- I did register it after slugging it out with Canon's website and finally being allowed to register the machine.  (Took about 30 minutes)

I get no TWAIN dialog asking me whether to scan duplex by the ADF, or set any parameters.  I can't find a driver specifically for this (apparently unknown) machine.  Windows 10 is using the generic MS driver.  I'd like one from Canon designed for this machine.



Type the circled web address and you should get to the indicated page.

Found it by searching maxify gx7021

Canon support told me that there is no Canon scanner driver- just the scan utility that comes with the printer driver indicated above.  They use the MS generic TWAIN, and WIA drivers.  I write this in hopes that it will save someone the time of reinstalling something they thought they'd already installed in hopes of finding a missing scanner driver, which is what I did.


Canon makes and sells stand-alone ADF full-duplex scanners.  They provide TWAIN and WIA drivers for at least some (all?) of those.  Why not for this?  (You probably picked up that now I am looking to buy an actual scanner.) My under-$300 Brother B/W workstation printer/fax/scanner came with a full-featured scanner (that could scan in color at 1200dpi), ALL the drivers, and the software.  Why didn't I buy another Brother?  Because the ones comparable to the GX7021 are out-of-stock at every retailer I trust.


Thank you- I first tried downloaded and installed all of those packages. And no Canon TWAIN driver is called when I try to scan from Paperport.  Trying WIA locks it up.  Device manager shows the MS drivers are installed.  And I can 't get support to recognize the Model Number by phone.  That's a big problem affecting product value.  I don't want to waste much more of my time as I have an immediate need.  Brother stuff is reliable, and they offer support you can actually access.

Understood. I will stop trying to help.

Honestly, I appreciate the time you took to try to help.  As wonderful as the hardware is, the software is just super-frustrating.  I have much to do, and have spent many hours messing with this.  The hardware is polished.  I wish the software (and Canon's website, and their phone support) were also.  Thanks for trying.


Please click HERE for more information about scanning with the WIA driver. If the issue persists, it's recommend you use the IJ Scan Utility software that came with the printer.

Thank you for the suggestion.   I was able to get to support by calling Canon's customer service  dept. number, choosing sales, then explaining that their IVR system doesn't understand "Maxify GX-7021" as a model name.  Canon doesn't provide a scanner driver.  They use the MS-provided driver.  Their scan utility is the ONLY way to access all of the scanner's features.  They wisely chose to provide a printer driver so that we can print from other third-party software and get good results.  I wish they'd see the light with the scanner.  Using it is not too unlike trying to get support for this wonderfully designed device's software.  It's very convoluted, and incompatible with an efficient workflow.

I do appreciate you taking the time to help as you could.   I know if I have a printing issue, this is a great resource.

Now I have this eMail from Canon: "Thank you for your call.  We highly recommend that you register your product, which will help you take advantage of all your support options using our MyCanon Account system."

My product is registered, according to Canon's wesbite (and the fact that I am allowed here), the Sales guy who transferred me to Tech Support, and the Support Tech I spoke to.

C'mon Canon- try to get it together.

If by “here” you mean this forum, it has nothing to do with product registration. One doesn’t even need to have a Canon product to register for the forum.
