WIA Windows Image Acquisition Service won't start - Scanner won't scan - help?
THis is similar thehp officejet 8500 wireless A909g printer with scanner project you did.
I have an hp officejet 4620 wireless printer with scanner, and its software installs OK but can't scan. I am told This is because WIA which it relies on will not start and function properly. I to have have paint program "from scanner or camera" is greyed out. I can't scan in paint either.
I spoke with an HP tech support highest Tier level.. who boiled it down by saying that "the scanning drivers built within windows are not working properly." He goes on to mention TWAIN_32 and C:windows scan folder wain_32, out of context, as a possible problem source.
I have also gone into
I go into [url removed, login to view] and enabled all supporting dependencies DCOM, and RPC services which work with WIA Windows Acquisition Service. I was even able to enable service status: WIA which "SAYS" started, but when I refresh it it says stopped. All related services are set to automatic. In the recovery tab of WIA, all failure attempts are set to restart the service, and reset fail count after 1 days, and restart the service after 1 minute.
The error message I received when I try to scan is "HP officejet 4620 was not found"
I do not understand all the aspects of the WIA system, and am looking for someone with more experience in operating systems, to troubleshoot this issue and where it leads. Final resolution of this project would be to successfully install the HP software (which I've uninstalled and installed 10 times already)
remote access to this computer for resolution is OK.
