HP M477fdw will not scan to network folder (anything above 75 dpi)

[jdslaw]

I recently changed my work computer from a Macbook Pro (running OS High Sierra 10.12.6) to a Mini Mac (running Mojave 10.14.1).  On my Macbook Pro, I was able to scan documents from my m477fdw to a network folder on my laptop without any issues.  Now, on my Mini Mac, I am unable to scan anything above 75dpi to a network folder.  I keep getting the following error message: "Cannot write to \\192.168.1.105\scandocs. Destination folder is read-only, has the wrong permissions, or is no longer available."

My firmware datecode is 20180201.  I downloaded the latest update directly to my printer/scanner this morning, and still having the issue.  I have also downloaded the latest driver I could find on HP's website for my OS.  Also, I ensured that my file sharing permissions are identical to those on my Macbook Pro, so there I'm not sure what the issue is.  Please help.

Same problem here on Mojave (10.14.2).  I can scan to network folder at 75dpi, but 150dpi returns the same error you reported.  I have been unable to solve the issue but will note that many others have posted similar issues.  One user reported luck on the similar M277 printer with an unreleased firmware (20180321SC) so HP must know how to fix it.
