Scanning Weirdness ENVY Photo 7858

[Sparklowski]

Attempting to scan multiple (4 - 3.5 square) pictures at 1200 dpi. Using both/either HP ENVY Photo 7800 series-HP Scan and HP Scan Extended software I experience the following issues:

1. Four separate files are saved with only part of the picture with the rest being a white background - it looks to be the right size of the picture, but captures only part of it the way it is laid out on the scanner.
2. One or two of the files save, the others not being saved.
3. With above, I think, after cropping an image, and then click on another image in the left "thumbnail" section to crop, if I click on the previous picture it will no longer been seen in the viewer/cropping section.
4. I can now tell that when I crop a picture and it stops letting me crop, when it won't let me move the dotted lines anymore - which I don't think it should ever do - the above issue will happen.
5. My favorite issue - I perfect the cropping and click Save, I then get the dialog box to Save As, as I do with all other instances above, and then wait a while - all the while hearing the scanner doing its thing - and then the folder opens up as if something saved, but nothing at all saved. I don't necessarily have the problem as described in 4 above, there are no problems with cropping. It's not an issue with the path - I've uninstalled and reinstalled the printer software and fiddled with the scanner software so many times to fix this that choosing the right path is now second nature. I also know it's not a path issue because...

Any/all of the above problems can happen one after the other. I simply hit Back and try again. HOWEVER, when it doesn't save any images - or perhaps the files are invisible, but I'm thinking that's not it - the scanning software will close itself.

Only once, out of 50 or so attempts to figure this out on my own did it save all four pictures as complete pictures, but in that instance I didn't do any cropping at all. I then tested the no-cropping theory again and was unable to reproduce that minor success - either one of 1-5 would occur.

Tried HP Scan and Capture as well as the Windows scanning software. Neither of those allow you to scan multiple pictures at a time, saving them as separate files. Again, uninstalled and reinstalled the software, even doing the PRINTUI.EXE /s thing, to no avail. Ran Scan Doctor 3.5, and even though it said there was a later version of the software available and it downloaded it, when it came to the point to choose the printer to update, the printer was grayed out. Same experience when I download the latest firmware from the HP site.

So here I am, desperate. Thanks in advance for any new suggestions. I should add I searched through the 8 pages of results on this site when searching "HP ENVY Photo scan," and tried other search terms as well. Tried a lot of the solutions suggested for other issues.

You might have to settle for scanning at this maximum DPI one image at a time.

The maximum scanning ability of the printer is not "just the printer" hardware - there are other factors.

Scan Resolution, Enhanced Short Disclaimer

The maximum dpi at which you can scan is limited by available computer memory, disk space and other system factors.

The "other system factors", though not explained in the source, might be one or more of the following:

Total bandwidth available for the scan - scanning at very high DPI, for example, would be best done using an Ethernet connection as opposed to trying to accomplish the task using a wireless connection between printer, router, and computer.

Scanning depends not only on a very stable and fast network, it is also impacted by your computer's ability to dedicate resources to the task.

Scanning at very high dpi in an attempt to increase the quality of a low density image is not likely to produce the expected results.  I am not saying this is what you are attempting - it is an observation only and not meant to engender any defence.

FYI only:

HP Scan Extended is an older subset of the HP Scan software that does include the nice "detect boundaries" feature that is (was) not always available in the HP Scan software for all printer models.  The HPSE software is likely still compatible with the latest versions of Windows 10.  Having said that, know that the software is now nearly five years old.  It may not provide all the benefits for which it was originally intended.   The software is not as likely as important as other factors - it is part of the consideration.

What to do?

Suggestions / Observations

• Try scanning one photo at a time when scanning at the highest DPI (1200).
• If you have not done so, connect the printer to the network using Ethernet.
• Upgrade your router - this is one of those instances where newer, faster, stronger is better.
• If your computer can only support the slower connection rates, upgrade / replace this component.
• Upgrade your Internet speed - old, slow, data speeds are not conducive to the needs of high grade product imaging.
• Try using Paint (mspaint) to scan at this higher DPI - again, one image at a time and while the computer is not trying to do other tasks.

Example - Officejet Pro 9025 scan high-density image / photo at 1200 DPI - save to computer

Reminder:  The speed at which the scan completes and results are impacted by all the "Players" in the setup:  Computer, network stability and speed, connection type, printer model.

Thank you very much for your insight and suggestions, Dragon-Fur. I was hoping a lower DPI would do the trick since everything else is as you suggested, but I think it's the software that's giving me grief, or at least how its behaving on my particular PC. Until recently I had only scanned documents and 8 x 10 portraits (at 1200 DPI) with no problems, but I experienced the same problems when I gave 2 pictures at a time a try at 300 DPI. I'm picking back up a project to scan old family photos, so it will be important to be able to do as many as will fit on the scanner bed at a time (I previously used another brand of all-in-one that was falling apart after a decade or so of use so was replaced within the last year). The logic of the high DPI is the idea that, should the day come to present a slideshow on an 80" class screen, we'll get a better picture (not sure if my reasoning is entirely correct).

In any event, time to explore paying for different scanner software. And thanks again for your help.

You are welcome.

The higher dpi helps if the original photo / image is also at a very high dpi, else the results are a high dpi scan of a low density image.

This is a relatively modest grade printer that includes a couple of nice features.

In theory, scanning more than one photo at a time at 300 dpi should not overly tax the printer. 

From what I have read, the printer supports dual band wi-fi, which while not necessary for the tasks, adds the versatility to connect at either 2.4 GHz or at 5GHz.  The best connection, of course, for stability and scan performance is likely Ethernet.   For best results, you need a decent computer on the other end of the equation, too.

What happens if you use HPSE (Scan Extended) and let the image boundaries stay as "detected", that is, do not pre-edit or crop the image before saving? 

Yes, you may need different software, or a heftier computer, network, and / or printer capable of the heavy lifting necessary to scan, separate, and handle saving edited photos as part of the process.

I might have missed something.  It happens.  

If I think of anything useful, for example, something I have missed, I will post back.
