Instead click on the red X to close the window.
When running the above it will identify your printer, and prompt you to install the latest HP Smart Software. Instead, look under "drivers" and download "I nstall HP Easy Start".
DO NOT GO with the recommended "HP Smart App". but it may differ for other models (although I doubt it, the software looks like it's intended for all HP printers). The link here happens to be for my printer. Go to the HP website to download drivers. Go to System Preferences > printers&scanners and remove the printer. scan tool shows preview, but then when scanning in color complains about color format. I was suffering from the same issue with an HP LaserJet: I am on a Mac and this is the only solution I have found so far that works well and allows me to scan in color. Of course this means that Adobe has already fixed this exact issue for Photoshop years ago, and just hates their own Acrobat customers for some reason. the PDF file(s) in Adobe Acrobat/Reader as normal. You should now be able to open, edit, etc. Then just click scan and just close each photoshop document as it opens up.
I also recommend using the document feeder if your printer is equipped with one, as it will automatically pull in the next sheet each time.
(You can also tell it what to name the file(s), where to store it on your computer, and whether to store each page together as 1 file, or each as its own file). If you happen to have Photoshop installed, you can fire it up and use the "File -> Import -> Images from device" feature, and change the "Format" to "PDF". Since Adobe insists blantantly ignoring a not-so-rare issue for the better part of a decade, I figured I should at least post this for the poor souls doomed to deal with this issue forever so that they at least have a chance.
I found a workaround for scanning into PDFs ( if you have access to Photoshop)
