I can not access the scanner software PrecisionScan LTX and while trying, the computer is trying continually to access "A" drive. A process hppsapp.exe is running in Task Manager and requires ending to stop the "A" drive accessing. Should "stimon.exe" be there in XP?

I have tested through scanners in control panel where the scanner is listed and tests OK.
Have tried numerous times unloading and reloading software and drivers. I am using sj657en.exe.

I have recently installed a new graphics card (Radeon 9700PRO) which required an up date of MB drivers to Hyperion 4 in 1 v455vp1.

My OS is XP SP2

I would appreciate any help on this.

It appears you have the latest driver.

I haven’t had a HP scanner and XP at the same time, but I think all HP scanners require Still Image Monitor to be active – it shows as “stimon”.

Something that sometimes works:
Uninstall Precisionscan.
Do a search for twain and twunk
Remove any twain & twunk files or folders you find in the Windows folder only.
Reinstall Precisionscan.

Thank you for your help "Slipe", but unfortunately this has not fixed the problem. From what I have been told, Stimon is not a function of XP.

If no none here can figure it out then post at HP message boards The scanner boards are under digiral imaging on the left at the bottom.

I have a HP ScanJet 4470C scanner, and it works just fine with STIMON disabled in the MSCONFIG "Startup" tab, whether I'm using it with my 98SE desktop or my XP SP2 laptop.
