"Manual Duplex" Scanning?

Hi All,

 

Brand new G7020 in place and playing with it to learn how to use the features.  What on earth is the "manual duplex" mode I can select in the IJ Scan Utility Light software?  Does this mean that I put my stack in the ADF facing up, and then turn it over and scan again to complete the process?  Since this places the last page on top after flipping, there must be a built-in correction to sort the pages properly?  Really disappointed that there is no auto-duplex scanning (some of my older Canon printers were excellent at this feature that seems to be GONE in IJ printers now), so need to figure this out.

 

Thanks in advance!

 

Bill

Greetings,

Manual duplex means you have to manually feed the two-sided document, one side, then the other during the scan operation to capture both sides of the page. 

 

Automatic duplex scanning is not gone, its still alive and well.  Unfortunately, not on your G7020 which I'm surprised as well since its currently the flagship in the MegaTank line.  Must be some type of design limitation.  (Manual 2-Sided Scan)

Re: "Manual Duplex" Scanning?

Thanks for the comment. So you’re implying that this would be done one sheet at a time, yes? Four two-sided sheets equals eight separate single sheet feeds, no stacking in ADF?

Re: "Manual Duplex" Scanning?

I just found this set of detailed instructions for another printer: 

 

https://support.usa.canon.com/kb/index?page=content&id=ART171047

 

This will make it MUCH simpler to scan a stack of duplex documents if it works the same on the 7020!

 

If it works, I will mark this comment as the solution.

Re: "Manual Duplex" Scanning?

I completely agree that it's crazy to pay so much for a printer and not have it be capable of duplex scanning.  It's very disappointing.  Having looked at the solution given, that printer does not perform duplex scanning either.  Hopefully, it's something that can be fixed with a software update.

Re: "Manual Duplex" Scanning?

I looked up your recommended unit for substituting.  If it did duplex scanning before, then it doesn't anymore.  I wish this wasn't such a hard-to-find feature.

Re: "Manual Duplex" Scanning?

So how does the manual duplex scanning work when your document has more than two pages?  I can find no reference to multi page manual duplex scanning in any Canon support articles or manuals.

 

Can you place a 10 page 2-sided document (5 sheets of paper) in the ADF have it scan the front of the 5 pages, reload it to then scan the back of the 5 pages and in the end have a PDF with all 10 pages in the correct order?  If so, I can live with this.  However, if it instead requires each of the 5 pages to be individually scanned front and back to acheive a 10 page PDF in correct order then I may look for an auto deplex scanning model.

Re: "Manual Duplex" Scanning?

The way duplex manual scanning works is by you scanning one side and then manually flipping it over to scan the other side. It doesn't matter if you use the ADF or flatbed, it's the same for both.

You could do what you say, but you wouldn't be able to rearrange the order of the pages for it to look right. The scanning program is extremely basic, aka circa 1995. From the perspective of someone that handles a lot of paperwork, I honestly wouldn't bother with this unit. The G7020 seems to be designed for almost exclusively printing pictures. As an office machine, I would look elsewhere.

FYI, duplex scanning is the "blue unicorn" of features. It's near impossible to find because the vast majority of printers don't have it. I don't know why industry hadn't figured it out yet, but I thought I should give you fair warning. Good luck and reply here if you find it because I'm still looking.

Darklunaria, thanks so much for the quick reply! 

 

I was actually asking for the MB2120 but assumed that the manual duplex is probably the same since the softare (IJ Scan Utility) is the same.  You have saved me the disappointment of unboxing an MB2120 to find out the hard way.  I am instead going to spend an extra $100 for the MB5120 which has the ADF auto duplex scanning.

Re: "Manual Duplex" Scanning?

Update-- I ended up purchasing the MB2120 and turns out the manual duplex actually works the way I was hoping it would!  Compared to the auto duplex scanning, the manual duplex scanning requires just the one extra manual step of moving the stack of scanned output back onto the ADF flipped over.


The on-screen instructions are comically incorrect in that they instruct you to copy the same side rotated 180 degrees rather than flipping the stack of pages to scan the backs. After you figure that part out you are good.  It actually first scans the fronts (E.g., page 1, 3, 5, 7, and 9), prompts you to scan the other side where you just move the stack of pages in the order they came out but flipped over and it scans the evens in reverse order (E.g., page 10, 8, 6, 4, 2) and when you exit it resequences the document page scans into a correctly ordered single PDF. You do need to change the data format under Save Settings to PDF (Multiple Pages) to get this behavior.
