MFP 29w Scanner Issues

[User5555]

I am unable to consistently scan using my HP LaserJet MFP M29w.  I think the latest driver update may have broken it.

Issue:  When I first open HP Printer Assistant and scan, HP Scan opens.  HP scans (for a PDF), and the first scan appears in the left hand panel.  If I try to add a page, the scanner physically scans the page.  No page appears in the left hand panel.  I can save the one page that scanned and exit and try to scan again.  The second scan does not appear even though the "Scanning" popup progress bar appears and the scanner physically scans the flat bed.  A blank scan doesn't even appear, nothing comes up in the left hand panel of HP Scans.  No error message, no message at all.  Just no scan.  Screenshot of HP Scans after scanning attached.

If I wait long enough, cycle printer power, or restart the HP software, I am able to scan one more time before having to wait again.

History:  About a month and a half ago, I could print and scan with no issues.  I tried to print and scan after being gone for a month and a half.  The MFP29w printed with no issues, but HP Scans said it couldn't detect any scanning hardware.  I uninstalled and reinstalled the driver and HP Printer Assistant software.

The HP Print and Scan Doctor 5.7.3 returns all green checks that everything is set up correctly.

Hi Elohi,

Thank you for the response.  The recommended information did not help with my scanning issue.  If you read the original post, I noted that I ran the Scan Doctor program.  It returned that everything was functioning properly and displayed green checks on all the items.

Other  information:  I rebooted both the computer and the printer/scanner.  I ran Scan Doctor after rebooting both devices.  All green checks.

I tried two different USB cables.  Nothing changed or improved.  The USB port itself works fine for any other device plugged into it.  The printer works fine.  It is only the scanner feature.  The scanner does not seem to be synching to the HP Scan software when transferring over the resulting image.

It ended up taking me 4 hours to scan documents that should have taken half an hour at the most.  I would shut the HP Scan software down, turn it back on and try again.  It might scan one page and then return nothing for additional pages.  It might not even scan one page.  Power cycle scanner, reboot computer, etc.  I'm not looking forward to the next time I have to use this equipment.
